Hi guys, at around 40mph, I can feel my steering wheel vibrate. It continues to get worse and the whole truck shakes past 55mph. However, it becomes smoother after 65mph. I went to two mechanics and both said I needed an idler arm & bracket, pitman arm, and tie rod ends. I got all that done including an alignment and my steering is tighter but the vibe is still there. Good thing I didn't pay them to do it! I'm thinking imbalanced driveshaft or bad u joints. What do you guys think?

I had this SAME EXACT PROBLEM. I had went and got all the alignments and shit... And guess what... it still shook. There was a lump in my tire... you couldnt see with your eyes but you could feel it. I BET its your tires.

Definately have your tires balanced before you do anything else. A good balancer will know if you have a broken belt in the tire, the lump that Alen is talking about. It's cheep and anytime you have a vibration, especially at higher speeds, check balance. Even if it has been done recently, a weight could have fallen off or the right pot hole can damage the tire causing an imbalance. Driveshafts on newer vehicles rairly become unbalanced but I have seen the weights on those fall off too. A bad u-joint can also cause a bad vibration, to properly check them the driveshaft has to be removed and feel for "flat spots" when turning the joint in all directions. I have seen u-joints cause some strange vibrations, WITH OUT making any noises. Good luck!

Tires were actually next on my list for they are pretty shot. I was guessing drive-shaft also because i hear a couple clunks on take off. Maybe its both! lol. I'm gonna get some new used tires put on tomorrow and will let you guys know!

Well, replace your tires...seeing you need them anyway..and if it doesn't fix the issue, it could be a bad U-joint But U-joints usually give a loud clunk when you shift between PNRD with your foot solid on the brake. Also...they start to vibrate at 40 and its almost totally gone by 70...so I see why you could have been thinking U-joint.

 

Like was said...replace your tires first...you have to anyway...so it wont be a waste of money or anything.

Some GM trucks have a service bulletin about driveline clunks. A new nickel plated driveshaft yoke at the front of the rear shaft is availible that is supposed to allow smoother slipping in and out of the transfercase or transmission. Have seen this a few times, clunks at the end of a stop or take off, and between PRND. First time we tried just cleaning old yoke and greasing the hell out of it but the truck was back in a few months. The new yokes aren't cheap either, over 200 bucks if I remember right!

He has a vibration issue man....

Also, the driveline clunk for u-joints and slip yoke is a very different sound....and u-joint clunks also present with a vibration accompanying the clunk.

 

Good Info though none the less.

And I can only speek for myself here, I have been a licensed mechanic for over 10 years and I have seen several u-joints causing a vibration and NO noise what so ever.... besides your teeth rattling, lol. Had one in last week.

Ahhh...guess I'm starting to go blind too with the deafness...LOL

Yeah I have seen lots too....depends on how bad they get. If they vibrate for a while though...they will inevitably start clunking.

 

And yeah...could be both.

No worries Nytemare, you're totally right... One note about u-joints, FIX THEM ASAP!!!! My father has a 2004 K2500 duramax/allison and at 65,000 miles on the way back from Florida he noticed a slight vibration. They got home, dropped the 5th wheel and came to see me. I told him leave your truck and take mine I'll check it in a bit. Well, he decided to get back on the expressway and find out at what speed it started and how bad it was w/o the 5th wheel attached. Long story short, 5 miles on the e-way and BANG, u-joint failed, and cracked the Allison case 3/4 of the way around it. OOPS!!! Should have listened to me. 4500.00 later, normally probably a $8-10,000.00 job, he got a reman Jasper in it with a heafty core charge...

Newer tires put on and still vibrates. Looks like its the u-joints. I'll let you guys know what the shop says!

More than likely...yeah...let us know.

Well the vibration is gone. We first pulled the shaft and checked the u-joints. The rear one had a flat spot and was missing a clip. The rear pinion yoke has a groove dug in it from the pinion seal wobbling and caused a rear dif leak. The mating surface on the yoke wasn't smooth either. So after a new u joint and yoke the problem is gone. Now I can hear that I have a bad tire or wheel bearing lol. If its not one thing its another!

      2013 2500HD 6.0L intermittent no crank no start

      By linc45bn · Posted

      I've got a 2013 2500 6.0L Flexfuel. Drove the truck earlier today with no issues. Went to run an errand tonight and noticed key fob wouldn't work. Figured battery was dead, so replaced fob batter. Still wasn't working. Grabbed my other set of keys with the other fob and that one wasn't working either. So I manually unlock truck and insert key. Interior lights come on, dashboard lights up, turn key and truck starts. Turn truck off, like a moron, and try starting again. This time no crank, no click, no nothing. Lights still come on and dash lights up, but now I'm getting a service 4wheel drive, service tire monitor, etc. Check voltage on battery and Im showing 12.2v. Throw my battery charger on it and give it 15 mins and try starting again. But still no crank no start. Decide maybe its a bad battery, run to autozone grab a new one and put it in. Same issue. Disconnect battery and let it sit for 15 mins. Try again and still nothing. I had manager to roll the windows down earlier as its a humid night, but now I can't get them to roll up. Power locks are also not working now. Then randomly I try the key again, and it fires right up. Immediately I roll up the windows as we have nothing but rain forecast this week. I shut it back off wait 30 seconds and start up again. Worked a 2nd time. So turn it off, start putting things back together. Try one more time, and back to no crank no start. And now the car alarm starts going off. Had to disconnect battery and leave it that way for the night as I don't think my neighbors would appreciate my alarm going off again tonight. Any thoughts or help would be appreciated.

      GMC 1500 Illuminated Front Grill Emblem REPLACEMENT.

      By Peoplemvr · Posted

      Hi there.  Long time lurker, first post.    i have read the previous posts regarding the water ingress problem with this emblem.  I bought my 1500 SLT the  summer of 2025 new and after reading the MANY problems with these emblems failing I decided to install one anyways.  As per a YouTube video, I sealed ( or tried to) this sign with silicone sealant around the outer perimeter joint and the holes that were already somewhat sealed on the rear plate of the emblem.  And installed the connector assembly using dielectric grease on the connectors. The installation looked great and worked well for about 4 months……then FAILURE.  Grrrrrr…… I live in the great white north and wash my truck weekly in an automatic car wash  to keep the salt off.  Let me tell you that removing the old, failed emblem is a whole different animal than removing the OEM individual letters without removing the grill assembly. Mainly because the illuminated logo is built differently than the original letters which  you can remove the red surface lettering with a knife or some kind of blade which gives access to the tabs which hold the logo onto the grill. So I had to essentially destroyed the old emblem to remove it. Doing so killed my chance of doing somekind of autopsy on the failed , old logo.  But there was plenty of water inside when I ripped it apart.  Prior to installing the new assembly I tried it with the old harness and it works fine.   Does anyone have any insight as to where the water is getting into this emblem? I intend to seal the new logo with slow curing epoxy this time around using a syringe.  I think this newer emblem may be an updated unit which I hope GM got the vendor to fix. It has an October 2025 date on it.    If this one  fails,  I am just going to revert back to the non-illuminated letters….AFTER PULLING THE GRILL.    Any thoughts on sealing with epoxy would be appreciated. Thx!   Doug

      PS: Here's pic of the 2014 wheels I'd like to run when it's not winter. Stuck my finger around new wheel caliper setup. Very little clearance. I suspect these won't fit, but won't know for sure till I try.   Edit: And my first mod. Stubby antenna from the old truck.
