Shocks are great. Truck rides smoother (and softer in some cases) then my dad's 02 with IFS.

It only happens around 45 and when it does it the t-case lever kinda rocks back and forth. Slower or faster it quits. lol



To OP, sorry for threadjack.

 

Does it get better if you turn off overdrive?

 

Yeah, a bit. Still does it.
And it's not a shake like a misfire, it's a BOUNCE. Like the tire bounce I had before they were balanced.

 

Rotate your tires and see if anything changes.

 

You know, funny thing is, I just drove it...and no bounce.
I guess I never noticed that it left.

 

Mine is doing the same exact thing. Mine is a rebuilt trans with all new internals. It starts when the rpms go down and you try to start cruising in that gear but if you give it gas or let off completely its fine. What did you do to fix it???

 

Resurrecting ancient threads isn't going to help you......

Please start your own thread with your symptoms, any work that has been done on the truck recently, and anything you have tried to solve the issue.
