Shaking shuddering during acceleration

Just finally got my wheel bearing assembly replaced last week an got new tires, now my Libby started to vibrate under light to med acceleration and above 40 and lessened when taking foot off gas.. Started yesterday an got worse today.. Was not present for first min or two in the car today... Please help. Buddy said he had same kinda problems with bad spark plugs/ dirty injectors but it seems like a driveline issue to me??

Check u joints rear drive shaft and CVs on front prop shaft would be a good start.

what he said

What they said :icon_cool:

you mentioned new tires are the lug nuts tight? Check em again just to be sure. Maybe a bad (I know its new but) bearing?

Check the driveshaft yoke at the back of the t-case for play (up/down, side/side). I had the problem you describe on my Ramcharger and fixed it yesterday.

Transmission mount is something else to check.

A bad new tire is another thing to consider. Just 'cause it's new doesn't mean it's good...
