Hey guys,

I lifted my truck with the 7-9" Cognito kit. Everything turned out great but when you are following behind my truck, it looks like it drives at an angle. It's not that bad but it's noticeable.

My buddies truck is rediculous. It looks way off. Mine's not that bad but i want to know if anybody knows what causes it and if there is a way to fix it. I hope it's nothing serious. Is it being caused by the blocks that were used in the rear instead of new leaf springs?

HELP

Did you get the truck aligned?

Jon

See if you missed the hole on either the top of the block or the axle side. Make sure that "pin" is in correctly.

Sounds like rear axle isnt squared up with the truck causing it to dog leg. If it was mine it would be at the installers shop tomorrow AM.

Yeah I have had it aligned twice.

Rear axle isn't lined up properly, the shop probably set the toe in front based on the rear (being out of whack) and as a result it tracks straight but goes down the road dog-legged.

So what is the best way to fix that because the shop doesn't align it in house. They send it out to Firestone and have it aligned.

I'm gonna take it in tomorrow morning and I kinda want to know what to tell them.

Thanks for your help guys.

Tell them that they missed an alignment hole in one of the rear blocks. You are lucky that it hasnt shifted and caused an accident or Worse!

Measure the distance from centercap to centercap on the drivers and passengers side, if the measurements are different than you for sure have a problem. -Jeff

First off,Sorry you fell into the hype.
You all are wrong. The front track width is wider. It will give the illusion that the truck is "Dogwalking" because you only see one side at a time when following behind. All spindle type lifts will give this illusion because the front track width is wider than the front.

Diesel-N-Dust,

Your comment would make sense but the problem is, the "dog-legging" looks to be at the same angle regardless of which side of the truck you're driving behind when i'm on the highway. That's what convinced me that i had a problem. I thought about your comment first that's why i had my buddy follow me one lane to the left and one lane to the right to verify that issue

Are you fighting the steering wheel?

One lift block in backward is the only reason otherwise.Check them they should be tapered to the front.

how do you truely know if you have this issue or its just like diesel-n dust is saying ?

If the truck drives straight and true, it is an illusion.

I used to get it all the time on my last truck, "your truck is dogwalking"The truck drove straight and true.
I had a Rancho lift. I followed my truck in my wifes car, I could see what was happening. It is an illusion.

I would try measuring the wheelbase on each side of the truck [front wheels straight ahead] and comparing the two dimensions. They should be the same. If they are different the problem is probably in the lift blocks, but it will need to be corrected. Was it a two or four wheel alignment?

I wrote that previously. -Jeff

The truck pulls pretty good to the right. i have had it 4 wheel aligned twice. I"m gonna go measure the wheelbase right now.

If you had it aligned, it shouldn't pull at all, unless the road is banked. Sounds like the blocks on the rear aren't properly set on the pins. Beside checking overall wheelbase, check the front leaf spring bolt to the front of the block, and double check the taper on the block is the same on both sides, left to right.

We are waiting....

? i was told by a gm tech that they are set up to gradually pull right in prevention of head on collisions, ie. falling asleep, etc...

I had the same problem before on a lifted 1/2 ton Sierra and it turned out to be improperly set torsion bars and also the alignment. Just my 2 cents.:blahblah:

I had the same problem. I bent the center pins in the leaf springs. all was better when they were replaced.

Iggle,:confused: what happened? was a block in backwards?

Im curious as well

Diesel-N-Dust is correct. That illusion is just that, an illusion, front track width is greather than that of the rear, so when looking fron behind you are able to see the back of the front tire being further out than the rear. This is most commonly viewed fron the driver seat, and to correctly verfy this, you need to be sitting in the passenger seat of the car behind your truck and look at the passenger side of your truck (in front of you), it will take a minute to see because your used to looking at the driver side and will take you a minute to adjust to the new line if sight. Dont worry, I believe that you dont have a problem, follow any lifted gm truck, and as soon as you get the correct line of sight you will see it. Its something that is hard to get used to, whenever i see my truck driving from behind you automatically think that the thrust angle (technical name for "dog tracking") is off, but its not, just wider front track.

I have had people ask me about my truck as well. The alignment and everything is well, it just the illusion. But I would check everything out if you are concerned with it, just in case something is really wrong.

if your wheel bases are different between the two sides, there is not possible way it will go straight without you correcting with the steering wheel. its like having rear steering. He said he is pulling to the right quite a bit, so i think the "illusion" thing is out.

My trucks looks the same way when viewed from behind. It does look wierd but it is tracking straight. There is an easy fix. Never follow your own truck, and you won't see it.:)

I didn't catch this post till today...

I'm not sure if this is a kit that we shipped out but I now its not our install. If you need more help with your problem feel free to call me and I can go over some things to make sure there is nothing the shop over looked on the install.

Thanks

catch20two , track width, not wheel base.

catch20two , track width, not wheel base.

no, he was right. the trackwidth would be different on most trucks, the wheel base however HAS to be the same from side to side. -Jeff

correct, wheel base has to be the same, but the track width f-r however is different(what i was talking about in my first post, trackwidth not wheel base), if wheel base was different thrust angle would be f'd requiring constant driver correction, I think catch2otwo was refering to my previous post, in which i was talking of track width, not wheel base. we are all correct in what we are saying, just talking about two different things. - Justin

gotcha. :)

I had the same problem. I bent the center pins in the leaf springs. all was better when they were replaced.

have deaver lift springs in the rear. Sometimes I think I am robby gordon in Glamis.
