I bought my 2004 4x4 XLT Screw in June of 2004. Because my 3-yr warranty window is coming to a close, I'm going to bring it in and have the rear-end shudder taken care of once and for all.

I think it's been a while since this problem has been discussed but it was "forumed ad nauseum" when the 2004s first came out. Between 55-65 mph, and especially when accelerating, and especially when accelerating uphill at those speeds, the bed of the truck starts its hop and shimmy, severely at times.

I was wondering if I could get replies to this thread on what different things the dealerships did to fix this problem and what success stories you might have.

Thank you in advance!

Replace driveshaft and rearend clutchpacks. I had both done on my 05.

i belive there is also a TSB for correcting pinion angle
