Well all fixed. Got it back at the end of April. No issues, drives super smooth. Zero noises. They had to put a new rear end in the truck.

Possibly...Hopefully not. Either way, they're fixing it all no cost.

Took back to the place I bought it. They are going to tear the rear end apart. Funny, when I dropped it off, the sales associate (she has no clue what vehicle has what in it) said "they fixed a pinion seal leak and the owner was hoping that was going to fix it." I told her once it's done, I'm going to drive it to ensure it was done right and have my mechanic look at it again. She reiterated that it will be done right. Thanks for the assistance!

Hello. Bought a used 2002 GMC Sierra 1500 SL Ext Cab Stepside with 4.8L V8 last week. Owner of the shop advised that they had the pinion bearing replaced as well as tie rods. Said if I feel vibration it should go away. I noticed at deceleration, under 30 MPH, I get a howl and slight whine. I decided to test drive it and closed the deal. I took it to a shop I'm familiar with and they said pinion bearings are bad without taking it apart. Called the seller and they said there's no way thats it but to bring it back and they'll check it out. Could it be the bearing in the yoke area (think that's whats its called)? Or as the video describes, the preload came loose somehow. See the video I found, this is exactly what happens. Yesterday, I crawled underneath. Nothing is loose, thinking it was driveshaft or u-bolts. Noticed I have 2 piece driveshaft. Carrier bearing in the middle looks new. Bolts are still steel colored Any help would be appreciated. Also feel a thunk sometimes under my feet while driving and decelerating.
