88 truck
thought it was my rear driveshaft ujoint at the t case but i replaced it and the vibration got a little better but not much...i jacked up the front end and didn't find anything to be abnormaly loose or anything... stumped... could it have something to do with the t bars being cranked up?

u might wana try greasing all of the fittings in the drive line, i had the same problem a lil while back, and i just greased everything and the vibration went away in like 2 days, i guess it just really needed to be greased, hahaha

it can, if you never had the truck re-aligned afterwords.

as a side note, don't you have to re-balance a driveshaft after installing new u-joints?

I cranked my torsion bars and it didn't make any difference in vibration. When I changed tires however (used), I got a strong vibe from just about the same speed...45-60.

sounds like a bad tire to me.

what brian said could be it, and it could be your tires are out of balance.. id start with getting your tires re ballanced its cheap and easy. i bet you it will help a lot

rebalance tires and get your driveshaft re-balanced too. The weight on it, very likley could have been stripped off while wheeling... Did you hit your driveshaft recently? That can do it too...
