Vibration at higher speeds.. 50mph+
Got a 96 grand Cherokee 5.2 v8 full time 4wd I just swapped out the front axle from a CV style yoke to a U joint yoke style axle. I drove it around for awhile without the front driveshaft (for different reasons) and it had no vibration problems so I dont think it's my tires being unbalanced.. So I picked a U joint style driveshaft off a junkyard zj and put that on the new front axle and now when I get it on the freeway the jeep begins to vibrate randomly and it comes and goes often.. It seems it vibrates more whenever I let off the gas and begin to coast at high speeds..
Please let me know any ideas might help thank you!!
