GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hi there, I am Cam. Can i get your first name please?
With your vehicle, how long has this been going on? Any recent repairs to your vehicle?
OK Ken. I can only assume this was not there prior to the tie rods and alignment, so with that in mind I would like to start by checking the work that was done. Is everything tight? Any damage to the wiring for the front wheel speed sensors?Look at your Toe setting. With the wheel straight you can eyeball down the sidewalls of the front tire and see where it lines up on the back. It should be almost perfectly straight. The toe in spec is very small, almost non existent. IF that’s good then we need to see if a wheel bearing is failing. Lift the front end and see if there is any play in the wheel bearings. Check the axle shafts.I know these are straight forward things, but I feel they are needed as this sounds like a mechanical issue.
Ok, did you have the alignment done at a shop then following the repair?
Something could have happened on the alignment machine. I know ours is a pain at times. Check out that toe as I mentioned and see what you find.
Can you demonstrate it while driving? It sounds like the front is binding.
Is the abs or traction system activating?
Ok after you verify everything is good, see if disabling the traction helps it. If not then I really think we need to revise the alignment.
The switch disables the traction system, nut not ABS. See if its different if you turn one way vs the other. If not then look at the alignment. IF so, then we look to a wheel speed sensor issue.
Ok, so not ABS. Then thinking alignment. Since that was just done and it started after that, lets revisit that and see where that takes us.
It should not be, did you just change tires over then?
I meant to replace. If no then let's explore the transfer case. What's the condition of the fluid?
Ken, let me think about this while I go to the Gym. This is something odd.
Sorry Ken, I got side tracked with a personal matter. Why this happened after the repairs you did is strange. I would say its because of the alignment, but because that tests good I have to wonder why. Does it happen more when its hot?
When you replaced the tie rods, did you remove the Center link that the tie rods go into?
If so, then it's possible to put it in backwards, meaning the curved part going forward rather than rearward and it would change the toe on turns.
