Feeling Vibration and Jiggles in 2024 HD Gasser Steering Wheel

Texas Gasser · July 6, 2023

I have reviewed all the threads on this issue and it seems that the problem is being noted by the folks that own '20 and '21 HDs. My truck is a 2024 LT with the 6.6 gas engine. I now have 2900 miles on my truck. Since day one there have been vibrations and jiggles that I feel at speeds between 5 and 40 mph especially when turning left. Its not horrible but very annoying. At highway speeds the steering tracks straight and the vibrations/jiggles are nearly nonexistent. The jiggles feel exactly like you would feel if the tie rod ends or ball joints were worn out. I have greased all of the 9 fittings on the front end and installed a steering damper and neither have helped. I installed the damper primarily because on rutted dirt roads the steering wheel was jumping around more than I think it should. I have tried to move all the suspension parts and steering shafts by hand to see if something was loose, and everything was tight. I have read that there is a steering shaft bearing in the firewall that may be the culprit and that makes sense to me but I have not read of anyone having that replaced and the problem resolved. It seems my only option is to take it to the dealer and see what they say. I have driven half ton 4x4's a long time (both IFS and solid axle front ends) and have never felt this kind of feedback through the steering wheel. Any thoughts out there on what I should do? I love the truck otherwise.

Have you tried rotating the tires to see if the problem goes away? Perhaps you have a tire that is improperly balanced. It is also possible that a front tire has a bad and/or broken belt that is causing the problem.

If you are feeling it on rough roads at lower speeds, you are likely feeling hydraulic pulses through the system.

Tire and wheel balance will not affect that low of speed range.

You could try making sure you have the air out of steering system.

These trucks use old school recirculating ball steering not rack and pinion. They have that feel to them. I know what you’re talking about.

Wondering if you have figured out the vibration. I also have a 2024 2500hd gas with the exact same symptoms your truck has. I started noticing mine around 1000 miles. I currently have 1700 miles on my truck. I took it back to the dealership 2 weeks ago and they said they had two techs drive it and said it was normal. I never felt it when I first got the truck. Hopefully someone can steer me in the right direction.

Are you sure it’s not an alignment issue? To me, it kind of sounds like the toe of one or both wheels are not correct, causing it to “jump” when turning because both tires are not in sync.

64BAwagon · August 9, 2023

@Brianibew brings up a good point. Assuming there arent any faulty parts up front a good (non dealer) alignment/frame/heavy truck shop might be able to make some tweaks to the alignment to give you a better "feel"

These do steer different than any 1/2 ton or vehicle with rack and pinion, its old school for sure and they do tend to feel like they wander. Make note of the weight of that tire and wheel if you ever rotate them, they are heavy.

TW24 · August 9, 2023

In my case I don't believe this the alignment. This is a vibration that is coming up through the steering column at speeds as little as one or two miles per hour in Reverse or forward especially on a gravel driveway like mine. The feeling you get is that all of your lug nuts are loose. The dealer told me that this is normal with a 2500 or 3500 series truck. I don't believe this to be true at all. I have owned a new 98 Chevy Dually which had great steering, and I owned a new 2000 F-250 which also had great steering with no vibration. Both of these trucks also had the recirculating type steering like the newer 2500 and 3500. I think GM has a problem that they do not want to take responsibility of and are telling the dealerships to tell customers that this is normal. I hope to get to the bottom of it soon as I only have 1700 miles on my truck and don't even enjoy driving it anymore.

Sounds like you need a new dealer. I would start with contacting the service manager and see what he or she has to say. They have a network of technical assistance available. What youre describing is definitely not normal and borders on insulting when they try to tell you it is. Theres many things it could be and the only way to find out is by diagnosis, which btw they usually dont get paid much for.

A bad tire, a bad CV shaft, differential issue, U-joint issue, transfer case issue, trans issue and on and on.

Thanks 64BAwagon. Totally agree with you. Will keep you and others updated as things progress. If anyone else has had this issue please let me and others know of your findings.

I wonder if this had something to do with the recall Gm just issued for "fracturing steering shaft gear" #N232414720

TW24 · August 10, 2023

Haven't heard about this one yet. It's definitely worth looking into though. Thanks for the info

Nothing to do with that.

What's the best way to get the air out of these systems? Can you just turn the wheel lock to lock a bunch of times with the steering fluid reservoir cap removed? My 2024 is making that nasty pump hissing noise at idle that the GM TSB says is normal and I'm wondering if trying to remove air will help...

Yes call GM with your VIN and check for this recall.
