    2002 Yukon 5.3, 2wd. Rebuilt transmission and new TC around 25k miles ago. Recently put on new tires (Yokohama Geolander) about 10k miles. Warranty is up on transmission rebuild of course. Tires have been rotated twice, and rebalanced twice. Front end has been looked at twice, finding nothing wrong.

    Yukon has developed this shudder at the speeds of 45-55 mph which unfortunately is my majority speeds. If I quickly accelerate through it there is not always an issue.

    I’ve searched and I find out of balance, people needing new transmissions, TC, or ??? Am I really going to have to put a new transmission in this again?

    My other issue is a seal (the animal) type noise (as my youngster calls it) coming from the area of the passenger rear tire area. This has been recent and is noticeable at a stop, but not at speeds over 15-20 mph. Any thoughts? I’m not sure if it’s related.

    U-joints? Have you had anything behind the trans (driveshaft, rear end, pinion and wheels bearings) checked?





    I'm sorry you don't like my "noise" coming from your Yukon.

    the seal barking at you could be shot back brakes.

    I will ask to get all that stuff check on Monday. Thank you as I didn’t know any of those could be contributing factors. And lol at Seal.

    I’ll have back brakes checked as well. It’s noticeable when the vehicle is actually stopped. I was able to record it today thankfully so none of this “cannot duplicate problem”.

    Thank you for insights!
