Violent "clunk" after letting off gas?
Well, if its not one problem its another lately. I picked up my truck from the dealer today after getting my MAF replaced, and I noticed that when I hit the gas and rev past 2,000 around 40-50 mph, and let of the pedal quickly, there's a big "CLUNK" and relatively violent shake right under my truck. Maybe a tranny or driveshaft problem? I'm going to go get the driveshaft lubricated tomorrow to see if that helps, any other suggestions/ideas?
btw, i just put 300 lbs. of sandbags in the bed a couple days ago, dunno if it relates to it or not. Didnt notice it before putting them in though.

If it is your U-joints, greasing may quiet it down a little, but it will still fail. You don't mention whether you have a 5-speed or an automatic. Manual trannys and exuberant drivers are kinda hard on U-joints. Autos tend to soften the hammering and the shock on the U-joint. Popping the clutch is bad. But usually you don't even know why they go out...maybe some dirt from a mudhole, or rust from a water crossing. Check them out or get someone to check them out.
Oh, and give my best to granny...

By "hanger bearing" he might mean the center bearing on a 2-piece rear DS.

Well, I got my U-joints greased today and that seemed to fix the problem for about 5 miles....then it slowly came back, now its just as bad as before. I guess that helps narrow it down a bit but since I'm not mechanically inclined, I made an appoitment with the stealer on Monday to have it checked out. *sigh* Hopefully its covered under my extended warranty. Thanks for all the input!
