front driveline vibrations.. time to fix it.
my 98 xj has had some front end vibrations for quite some time now and it is time i fix this issue. i know the vibes are in the front end because they go away when the front shaft is out. When the shaft is in the vibes go away when i have it in 4wd and am on the gas. as soon as i let up on the gas they return. all the vibrations seem to happen at highway speeds. the jeep has a 6.5in lift on it. i know i cant expect perfect out of a Cherokee with 6.5in lift but i know it can be better than it is. my drive shaft angle is 10.5 deg down and my pinion angle is 7deg up. does this sound correct for the pinion angle? when i set it a while back i did some research on here and thought i had it figured out. the drive shaft is re built, as is the t case and the front axle was re geared and re built less than 2 years ago so i dont think the problem is there. any suggestions help. here is a couple pics of the drive shaft/pinion angle. (i just put it back in for the pic that's why there is no bolts holding it in) thanks.
