vibration

i have a 99 TJ on 35's, 4.5 suspension and 1.25 body lift, sye and tummy tucker tranny skid plate, 4.0L manual trans. 4.88 gears, ford 8.8 w/ auburn e locker/LSD, d30 open. stock front drive shaft.


ok now to my question
recently i have been getting a bad vibration on accel and up hills, feel it in my feet. i replaced the rear u joint that was bad changed pinion angle. and it didn't help
the vibe goes away in 4wd
i have a bad wheel bearing on the right rear
and the front drive line has slight movement at the slip, has alway been like it since i bought it

nothing changed when the vibe started i think it started when i made a sharp u turn, since then its been their


please help its driving me crazy and i don't want it to destroy something

Does the vibe go away almost instantly if you out the clutch down during the vibration? Good test to find out if it is for sure drive line or another component.

Sure sounds like ujoint or driveline related

Feeling it at your feet usually means front driveline. I'd D/C the front shaft and see if it goes away.

yes letting off the gas or putting the clutch in, makes it go away, same with being in sing 4wd drive. at cruising spend its barely noticable and its not really their if i get on it after a like 45-50ish and if i take off really slow it doesn't do it till their is a hard load on the engine/drivetrain

Look at your front drive shaft joints

removed the front shaft didn't change anything, it feels like something is knocking around the tranny area
