2021 Steering wheel shake

[JFaust]

I'm new to the site and hope someone can help.  I posted on an older thread but haven't heard back from anyone.  I have about 5,800 miles on my truck and now have a shake mainly above 60 mph.  You can feel the steering wheel shake in your hand and if you let go it really gets to shaking.  I had the wheels rebalanced and no luck.  I see for past years they have been doing a steering system reprogram, are they doing that for 2021's too?  Does it actually work?  Tomorrow the truck goes to the dealer so I'm trying to be ready for them.

Did they do a road force balance to check for wheel issue or tire issue. I believe the sweet spot is 15 or below. I would do that first and then move forward looking for other issues.

Well after the dealer visit my wheels have been balanced a second time in a week and did nothing to fix the problem.

I would suggest trying a different set of tires, if your dealer is willing. I had a set of brand new Cooper tires cause a vibration above 60, even though they balanced out within spec. The replacement set does not vibrate.

If the dealership balanced them twice without resolving the issue then they should still be looking for the source of the problem. Have you told the dealership they haven't fixed the problem? If so, what did they say? if not, that's your next step.

 

I wouldn't let the dealership off the hook yet, there's plenty they can do other than just a basic spin balance, i.e., PicoScope with NVH kit, Road Force Balance, rotate tires, replace tires, etc., etc.
