I have an 05 2500 crew duramax with an allison 4x4. I have the banks 6-gun with the PDA, monster exhaust and volant cold air. I am running 285/75R16 tires. I love the power and really like the truck. I am now having problems with the steering during parking lot maneuvers. Going slow the steering wheel will not move. You really have to work the wheel to get it to turn. My dealer replaced the flow control valve in the power steering but it didn't help. Now they are saying the tires are too big. Well the problem is for that to come in to play you must know the contact patch, type of surface and rubber compound. It just seems like a cop out.
What I am trying to say is that GM needs to wake up, I am exactly the type of customer you are loosing to Toyota. I owned a 2002 Tundra ext cab V8 and loved the truck. I can't comment about Toyota's service department because I never had to use them. The fit and finish was years ahead of GM. As soon as Toyota comes out with a 3/4 ton truck with a diesel I will switch and probably never look back. GM should be worried about me, I am your target market 34 yr old married with 2 kids and a disposable income. There is a reason they are close to going bankrupt. By the way my Tundra also had 285/75R16 tires and turned just fine. Just imagine a lighter truck built with better steering.

when i first bought my truck i asked the dealer if i put 265-285s on
my truck would it void my warranty they said no.the first time i brought
it to the dealer i noticed my tires feathering they checked it out and came back with its the bigger tires that are causing it.well i worked with
suspensions and tires approx 15 years now and never had larger tires feather like that o did i mention it was only the rear tires that were feathering fronts were great.my opinion is that if they make a truck to haul that much weight and to say tires are going to damage it is a crock
of chit. dont get me wrong though i love my truck and would not trade
it for another brand. i figured out the tires feathering were caused by
the rear being so light and how hard i accell. seen it on other bigger trucks also.

The new Tundra (saw pictures from the chicago auto show, will be a true full size truck with a 10k towing capacity. I'm curious on if and when they will bring a diesel to the tundra.

Back onto the subject, I had a tacoma and had serious issues with my dealership despite the truck not missing a beat. I truly love my current truck and don't regret it one bit.

But I do know the FHA DOT rule says they must fix Steering and Brakes the first time. But you might want to remove the 285's and go to another dealer asking if they can find and fix it.Stock tires on ebay are cheap

Have you put the stock tires on it to see if it repeats when bringing it in for service?That's what I would do.



Good luck

I had the same problem on my 01 Chevy as I do now on my 05. Same size tire and same problem. It seems the power steering is really weak on the Chevy trucks. Backing my toybox into it's spot can be really difficult, do to steering whell locking up, even though it is almost a straight shot!!!!!! The power steering is a JOKE!

Great.

My steering just started whining if I try to turn the wheel fast at 0 or 1 MPH.

I've had two steering shaft replacements, the speedometer just broke, and all this after fighting for a year with the dealer to get it running right.

46,000 miles, stock tires. Worst GM vehicle I've ever owned.

Toyota is going to have a diesel you say?

be sure to air up the big tires to 50 PSI.

One of my front 285's has a very very very slight leak...so like every 3 weeks if loses enough air to drop PSI down to 30 and the wheel becomes hard to turn when not moving. I air it up to 50 PSI and all is well again.

I received a very long survey from Toyota, asking what I like and disliked about my truck ('02 3500). Also, wanted to know how it could be improved. I think they are real serious, and yes, it seemed to indicate diesel power.

I don't understand why Nissan dosen't have a diesel. They used to run the smaller diesel engines they made in the old International Scouts.

Hey,

Nissan does, just not in North America. They have diesel powered Patrols running all over OZ & NZ!!

Mine has never done this until it hit the 30s here. Now every once and a while when backing out of a parking spot steering is almost not there. I feel like its 100% manual steering. I thought I had a flat it was so bad.

I Have 35x13.5's On Mine And It Also Gets Hard When Backing Up A Trailer Every Once In A While. I Just Apply The Brake Give It A Little Gas And It'll Turn Anyway You Want It To.

I'v experienced steering issues while backing my trailer. Was told that the boost pump is not adequate to run both the brakes and steering at the same time while at an idle.

Because the diesel has no vacuum, brakes are hydro-boosted off the power steering pump. paul1987 nailed it, if you are on the brakes at idle you are losing power steering pressure to the brake boost.

I run my 285s at 40psi and at 50k I have never had any steering issues at any speeds or at a standstill. Something in your system isn't working right because these trucks will turn the wheels on dry pavement with a 1000# snowplow hanging off the front of them. That's a h*ll of a lot tougher than turning bigger tires. As already mentioned I'd put stock tires on and then take it to the dealer.

only thing i can add to this is that gm dealer prices on parts are a bad joke, i can't believe anyone would ever buy any parts from them. If they don't have it at napa or autozone i just call a gm dealer, ask for the price and part number of what i need, and then go on line and get it for 40-50% less and i will continue this practice for as long as i am driving, and i encourage others to do the same. $475 for a rotor when Napa has one in stock a mile down the street for $99?

but that is for any dealer, My 00 Grand Cherokee had a bad tail light, I got one on line for 60$ but te dealer wants 200$. I just expect that from a dealer, GRANTED I've had to go to them for some parts, but that's only on a few items

Idle hit it, you arent making enough power to run the brakes and steering while at idle.

Go ahead and buy a Toy, it will be their first year and your post on the toy forum will be something like this. "Engine wont start tranny smokes and has no forward speeds. I towed 10,000 pounds and the truck felt like it didnt have enough ***."

stock tires and 6000 miles mine would not turn in parking lots. had the pump replaced and now with 57k miles it turns 33/13.5 TSLs like its no problem.

My boss had the same problem with his steering while braking.I did some research for him here on this site and read about a hydrobooster recall or TSB .At first they tried to give him the "tires are to big crap.,he has 35's.Then I printed out some info and they replaced it without a problem.It would have been $900.00 if he had to pay.Certain VIN numbers are covered.They have to fix it because it's brake related.

I'm with you on the whole ***** GM too. I've already decided they will never see another dollar from me for a new CAR,[( Crap they are trying to pass off as cars anyways( excluding the vette.)] and if I get any hassle at all on my truck,the new truck I buy every two years will be from another company as well.Customer service BLOWS.
Anyways try a search on hydrobooster and see if it helps.

JAy

You think your goin to get better, atleast their not cracking down on programmers yet. Oh yeah and if you want to buy a toyota.... go ahead we wont miss you:eek: . Just hook that sob on to 20000lbs and see how she does-:t . BTW i have 325/60/18s. and mine turns just fine, maybe its operator error:eek: :joke: .

We've had 285/75R16 size tires since we purchased the signature truck in 2003(took the tires/aluminum rims off the previous GMC Sierra 8.1 to put on the 2003 2500HD D/A). When those wore out, we replaced them with Revo's - same size. They were too worn to make a Powder Mt. ski hill winter (a 9% grade) so have put Michelin M/S for the season - again same size. Have never had trouble with steering/braking combo even at low speeds. My truck weighs in at 7100# So it sounds to me like a pump boost problem (or canuter valve? ):h )

Banshee42065 - feathering tire wear - had dealer do alignment this last time (brand new tires, new aluminum rims, better than the kid at XXX tire doing it...) the tech, although not seeing the old tires we had replaced, mentioned that they were probably exhibiting those same feathering symptoms, and did not blame the larger tire, but the camber adjustment (was at -0.6 with limits of -0.3 to +0.8 degrees) he also recommended, and set, the caster to 3.4 degrees for better steering, Note: this is actually outside the specs gm states (+3.5 to +5.5 degrees) - any alignment folks agree??

thats my area im in steering and suspension do alignments all day long
on those ferds.i checked my alignment and was dead on still have print
out of it but my issue was that the rear tires were feathering not front
thats why it bothered me so much.

BN, I feel your pain man. My '05 LLY 3/4 4x4 started having the same problems at 7K. Took it to the stealership and the cop outs started. First the 265 tires, then the replacement bumper, and finally I got the GM bulletine regarding "lack of steering" during "parking lot manuvers". Chances are you've got the same one, just as all the other GM owners with these hydroboost systems. Don't know if it will work for you, but here's what I did.....
Called GM rep from Oklahoma City and had a sit down with him and service manager at the stealership. Explained to GM rep that after 4 trips to the service dept., it had not been fixed, nor had they attempted to make any adjustments. That seemed to p.o. the rep. So he told the service dept. to bump up the pressure in the p.s. pump a bit to see what would happen.
Those hydroboost systems, as you have heard by now, are very much known for these problems, and it has been in engineering for years. The p.s. pumps are set at 1500 psi and have an operating range up to 1575-1600psi. They bumped my pressure up 15psi and that fixed it. No problems since and now have 30K. So you might run that by them,and it would be better to go ahead and get the GM rep involved if you can. Customer service seems to be higher when the "big man" is around, if you know what I mean. Sorry for the long reply.

Hey,

Go ahead buy a Toyota. If thats what makes you happy than do it!! I remember when the T100 was launched. They had it hyped up like it ( just like the Yankees did with Hideki Irabu! ) was the second coming of Walter Johnson of the truck world. And when it actually arrived it flopped. It was underpowered and the frame was about as rigid as wet spaghetti!! But if this makes you happy!!

Me personally am not scared about the upcoming Toyota truck line!! Bring it on, and when the Dust settles the DMAX will still be on top!!

MAke sure when you buy your Holly Grain Toyota,to move to Japan too.

So us americans can enjoy our american products.

Like said before,keep those imports and such. American heavy duty trucks just do it better. When the dust settles,we'll still be on top.

Maybe if the yoda fans wait long enough they can get a diesel/electric hybrid that would be real cool.:eek: :badidea:

I agree with you 100% to buy American. Support those who support you. The only problem is that most of your GMs, Fords or Dodges are made in Canada or Mexico(must be new states). Go look at your doorjams. If you want to drive an American made vehicle it better have a Toyota, Nissan, or Honda emblem on it. There is a reason that up until the early 90's GM owned over 50% of the US market, now GM, Ford, & Chrysler own less than 50% combined. The American worker is still making a quality product, it is just for the other manufacturers now.

When I look inside my door it says MADE IN USA.
Flint, Michigan.

Now I know all the parts don't come from the US, but it's made just north of Motor City.

Yep, assembled in USA from parts mostly manufactured in USA. The Hondas and Nissans may be assembled in USA, but the parts aren't produced domestically, there's no Nippon-Denso factories in the US that I'm aware of.

No matter what you say about the big 3 they all bring more money to hard working union americans than any of the imports, thats where my money will go.

Toyota, Honda, and Nissan are made in America but made up of something like 40% domestic materials while the Ford and GM trucks are made in America of 85-90% domestic materials. And I drive another Flint, MI built truck.

Yeah, I like my American made truck with it's ISUZU engine. I really do!

Isuzu but made in Moraine, Ohio thank you very much.

As of 5 or 6 years ago the 2 most american made vehicles (more that 90% US parts origin) were the hummer (h1) and the viper.

The products from the big 3 arent the problem. Its the dealers. Go to a GM/Ford/Dodge dealer looking at cars/trucks. Then head over to Acura/Lexus/Infiniti. The difference in the way you are treated is incredible. And then there is the service. Take a caddy or corvette in for service. A loaner - you must be joking. The japanese companies will set you up with a loaner, possibly even a nicer car than the one you brought in if its for a major issue.

Keep Censored over your customers and then wonder where they've gone :confused:

I've probably purchased my last new car. I'll either lease (for work) or buy used.

Yeah, I like my American made truck with it's ISUZU engine. I really do!

Joint Isuzu/GM DESIGN, but the engines have ALWAYS been manufactured in a single source facility in Moraine, OHIO. You've been on too many Dodge forums with that ISUZU engine B.S.-:t

didn't GM buy all the rights to the DURAMAX? and it was orignally a GM/ISUZU design...and being GM owns part of ISUZU...

I have a 2004 LLY. I had the same steering failure... no steering at a stop with foot on brake pedal. The dealer replaced steering gear & pump. It did it again a couple weeks later, so they replaced gear again. I went to pick it up and it still did it. They had it another 3 weeks and replaced hydraboost. It worked for a little while... now it is doing it again. What is this TSB? Do I need to talk to a rep about bumping up the pressure? Also, they replaced a line that they said was leaking.

I think all you guys are crazy. Who cares where its made, go off reliability.
The perfect truck has--
chevy body and interior(except the wheel wells)
cummings engine--because of mileage to.
cat transmission-- can handle anything you wanna tow.
as far as steering goes all of their systems suck.
Why cant anyone make a decent steering system for a 4x4?

I am running 285's and have been for over 160,000 miles and have yet to have a steering issue. I know lots of guys running bigger tires than that without problems. THat is kind of a crappy problem to be having. I hope you figure it out.

As soon as Toyota comes out with a 3/4 ton truck with a diesel I will switch and probably never look back.To borrow a line or two from Joe Diffie:

"You could set my truck on fire and roll it down a hill, and I still wouldn't trade it for"...anything else!

I would rather throw a chain over my shoulder, hook it to my truck, and try to drag it down the road before I would consider buying any foreign owned vehicle.

I didn't mention before, but I'm running stock wheels with worn tires... I want bigger wheels and a lift (4" because of 7 & 9 year old daughters) but I know how the game will go if I do it before I get the steering figured out.
