2018 grease zerks
 
I just brought my 2018 3500HD home a couple days ago. I have been looking through the docs on the number/locations of the steering grease zerks with no luck. I had 9 on my 2013 HD. I suspect it is the same, but don't want to assume. I have not had a chance to get under it yet to search them out.

Can you tell me how many I am looking for on my '18?

Thanks!

Silver Bullet 10-24-2017 02:40 PM

crickets....

Duratys 10-25-2017 11:01 AM

The 17's were 9 so Id bet the 18's will be the same.

dangerfield69 10-25-2017 02:05 PM

Do you plan on greasing it yourself? If so, you should be able to find them, but I would guess it's the same as the last number of years.

Silver Bullet 10-25-2017 04:34 PM

Yes, I plan on doing it myself. Just hoping to make sure they did not sneak a new one in on me!

carhauler 10-25-2017 06:09 PM

Nice thing is they are all clean cause they are not greased by dealer /factory or anyone that I have ever heard of , first time I greased mine I actually believe I heard the truck "sigh"

Silver Bullet 10-25-2017 08:43 PM

Seriously? No grease in them off the lot???

this was how I found it after the first dealer service , I asked and lubrication is not included in services

Silver Bullet 10-25-2017 10:10 PM

I guess this will get bumped up on the "to do" list.

TruckLover63 11-23-2017 01:49 PM

First oil change mine took quite a bit of grease in most fittings. Like 5-6 pumps, more on some, until starting to firm up. Now it just takes a pump or two. I do them every oil change at around 9K miles.

4 Speed Dave 12-07-2017 06:28 PM

I just saw this post today. I mentioned this exact thing in the L5P section last week. I just got my L5P truck last week and was doing a review of the truck this past weekend and found exactly what those pictures show. Not a lick of lube. I too pumped 5-6 pumps of grease in each one as well. I would have thought this is one of the first things the dealer would do but I guess not.

I'm going to be checking mine this weekend. I specifically asked the dealer about the grease when I bought it and was told that it would have been caught and fixed during the PDI if they were low from the factory. We'll see... :)

What grease have others been using? Anything in particular or just any old chassis lube? I have some JD grease (https://www.amazon.com/gp/product/B00CAXDJOE) up in the garage that I've used for other things, and it claims to work on trucks, but I was wondering what others have been using on their trucks.


Edit: Just saw this on Amazon. I think I'll probably grab a couple tubes unless folks have a better suggestion. It looks to be the standard chassis lube for GM vehicles. https://www.amazon.com/Genuine-Fluid.../dp/B000QIVOMY

Silver Bullet 12-16-2017 05:21 PM

I have been using the small tube stuff that fits my smaller grease gun I can get a Autozone or O'Reilly .

garrett41 12-16-2017 06:32 PM

I didn't get a chance to go over things yet but did glance at the upper ball joint zerks this afternoon. They do have some grease residue on them, so I'll take that as a good sign that at least a little grease was put in by someone along the way. :)

I may have spoken too soon. I wasn't real impressed when I climbed under the truck this evening.

The boots all look/feel pretty empty to me. Truck has about 150 miles on it. Here is the upper/lower ball joint and tie rod boots on the driver side. Passenger side looks the same. They are not firm to the touch at all either.

What do you guys think?

garrett41 12-17-2017 06:34 PM

And here are a couple of the squeaky clean grease zerks (lower ball and tie rod).

4 Speed Dave 12-24-2017 11:08 AM

Those photos were exactly how my truck looked when I took delivery of mine about a month ago.

DieselPro 12-24-2017 12:00 PM

A funny. I worked on a company's newer service vehicle. It was a lube service truck with 15,000 miles on it. Ball joints were shot. They never once serviced the service truck with grease. The truck had tons of grease products on it though.

Yeah. I greased the 6 easy ones the other day just to get them done. I haven't hit the pitman and idler yet as I was waiting on a 90* fitting

I also think I may have put one pump too much in one of the lower ball joints. They are still squishy and didn't start oozing grease anywhere, but I heard a slight "crackle" noise at the end of the last stroke :eek:. I've driven it about 100 miles since then with no sign of any grease coming out of them, so I think it'll be fine, but will be more careful in the future.

The tie rod boots appear to have a relief valve. I didn't put much in them, but noticed a tad bit of the old grease oozing out through a couple openings in a plastic ring around the bottom of them.

IdahoSteve 12-24-2017 07:03 PM

Yep, my 14' looked just like those. Never had any grease until I lubed them!

cwq21 02-15-2018 05:00 PM

I just took delivery of my '18, LTZ 3500 SRW Z71 last week. First thing I did was put it up on the rack and have my guys grease the 9 fittings. They were pretty much dry from the factory/dealer.

carhauler 02-19-2018 09:27 PM

Can you imagine all that $ GM is saving by never putting 1 drop of grease in any GM grease fitting not to mention the cleanup they don't have cause of residual grease around the assembly plants!!!!

davester 02-20-2018 01:10 AM

Don't forget the extra money they earn from you having to replace the parts earlier than if they were properly lubed.

Silver Bullet 03-15-2018 09:27 PM

On a different note...what grease are y'all using? I am looking to switch to something I can use on my truck and camper wet suspension bolts. I am hoping to consolidate and clean up my grease gun collection. I was looking at this...

IdahoSteve 03-16-2018 11:54 AM

^^That's exactly what I'm using^^

Great for my D'max and my tractor :thumb:

DuramaxEric 03-18-2018 12:45 PM

Have very good luck with this grease.

johnjr 04-08-2018 07:30 AM

I just had my free service done at the dealer last week, so yesterday I crawled under it to look at grease fittings and they are covered in road grime! They never greased it. Truck has 9500 miles on it and it probably has never been greased.

Dr O 06-01-2018 04:41 PM

I know this is an old thread but I hope someone can help me, for the life of me I can only find 8 grease fittings on my 17 3500.
4 ball joints 2 tie rod ends 1 pitman arm and 1 idler arm joint????

At the top of the idler arm assembly (the one on the passenger side). It is a real bitch to get to.

davester 06-02-2018 02:36 AM

If you are a wuss, you can get an extension hose with a gear nipple on the end to make it easier to gear that upper part of the idler arm. :-)

Silver Bullet 06-02-2018 12:41 PM

I put a 90 degree fitting on the end of my hose..works great! :D

Thanks! I have a gun with a 20” solid pipe. I put a 90* fitting on the end and it was a snap! Thanks Silver Bullet!

Time to get the truck to a reputable mechanic.

Beareair640 08-17-2018 02:39 PM

Looks like a good grease but I've been using Mobil ! synthetic grease for years. The main thing is to grease them on a regular basis.

Kpowell83 09-14-2018 10:02 AM

Threads like this are the reason I joined this site. I dove under my 2018 last night and the zeros on all 9 spots seemed untouched. The older and pitman zerks were harder to tell because I have a skid plate on and will need to pull it, but the ball joints and tie rods are for sure thirsty. Time to go buy a gun and grease. Really pretty shocked they don’t hit these during a regular service and from the factory.

What thread are the fittings. SAE or Metric? I want to replace the 2 that are on top but I don't need to crawl under there twice.

Thanks

68 4 spd 12-18-2018 10:38 PM

Wow am I glad I saw this post. Mine is 2 weeks old and I'm for sure going to grease it this weekend. I'm sure mine are bone dry.

I replaced those for the first time I greased my 2018 front end. I took one out and took that to the local auto parts jobber and they matched it up saying it was metric. Other than that I do not know the exact specifications. I was able to grease the rest of the fittings using a standard grease gun with a flexible hose and a straight end.

slevar2019 01-23-2019 03:57 PM

Unbelievable!
 
I just picked up my 2019 GMC 2500HD a couple of weeks ago and after reading this thread, I had to check the grease fittings on my truck. I couldn't believe it! I can't tell if the fittings are bone dry, by they're not "plump" as described in the thread. Anyone have a picture they can post on what a ball joint boot should look like?

D.Camilleri 02-03-2019 11:16 PM

All of the zerks on my 17 were bone dry when I got it home I greased it. Same with my 2015 and 2018 at work. Today while swapping tires, I decided to grease the old girl since I drove through a lot of water in CA two weeks ago. Idler arm is SHOT!!!! 29,500 miles.:wtf: I also noticed oil leaking from one of the rancho front shocks.

THAT SUCKS!

D.Camilleri 02-04-2019 08:29 PM

To the dealer on Thursday, service write said so how do I write this up? Steering feels loose? How about I was greasing what you guys don't and grabbed a hold of the wheel and saw play where there shouldn't be any..........

johnjr 02-11-2019 04:58 AM

Are they going to warranty it?

SonnyAK 02-27-2019 07:06 PM

Just greased all of mine. Fortunately the dealer had been hitting the easy ones - ball joints and tie rod ends, but I don't think the tough ones had been touched. They have been now!!

Grease fittings 2018 GMC 3500HD

On this one the Allison filter was on far tighter than necessary and took a fair amount of torque to break loose.

I greased the fittings in front and the three center ones were far easier to access after removing both the front shield and the added Z71 package skid plate. None of the zerks showed any side of a grease gun having been near them and the boots were empty. I don't think I will be using any of my "free" oil changes given the lack of proper PDI maintenance.

Someone tell me more about the grease requirements on the 2018 GMC 3500HD. I have not had to use a grease gun on a vehicle for years. This is my first 3500HD.

RDP 05-11-2019 11:30 PM

Would someone post location of the 9th grease fitting zert. Do I need to remove the skid plate in the front to get to it?

RDP 05-12-2019 12:25 AM

Need Upper idler arm pivot grease fitting location on 2017 to 2019 3500HD L5P. Photos How do I access to grease fitting. Do I need to remove any skid plates, special grease coupler?

I remove the front skid plate and have replaced both of those fittings with either a 45 or 90 to allow access. If you don't replace, you will have to turn the wheels to the right for clearance on the driver side fitting. The other side was too close to the radiator fitting for me to get the standard grease gun end on it.

Good luck.

L5P GMC 3500HD Upper idler arm grease zerk is accessed by removing the plastic engine splash pan, 4 each 15mm bolts. Location passenger right front, Use a 90 degree adapter on your grease gun. Mine showed no sign of being greased by the dealer since the truck was sold to me.

Dmetcalf 06-07-2019 12:12 PM

I’m reading this and thinking “really”..!!
 
It’s hard to think and believe truthfully that dealerships don’t go through these and ensure the front end of these very expensive trucks aren’t greased ..! Driving around on dry joints just can’t be good and should cause excessive wear ..! I just had my first “free” oil change and I wish I read this prior to that because I would have been under it checking on that ..!! Wow..!

johnjr 06-11-2019 06:38 PM

They don’t care simple as that! I only use my new truck to go to my house in Maine,and every time I come back I have issues and some will be addressed some blown off, can’t duplicate. It’s just a matter of wearing most of us down so we live with it or forget about it. Mine goes in tomorrow for service Stabilitrak,Service trailer brakes codes. And the second time for transmission lines rubbing on bracket behind grill. I gave up on the piss poor paint on a black Denali.
