I have had quite a few lifted jeeps and now have this 2000 Jeep Cherokee 4.0L 4Dr, Auto, 231 Transfercase, Dana 30, Chrysler 8.25. 180K Miles

I bought the Jeep with a blown motor, it has a 3-4" lift with 31" Tires, it has a fairly decent (interior parts rattle) vibration under torque at speeds 10mph up (not brake torque standing still)

I have done the following;

• Tried just front, then just rear driveshafts (Same either way) and tried different driveshafts
• Replaced both front hubs (they were shot)
• Replaced both front axle joints (they were shot)
• Replaced Rear Axle (Carrier Bearings shot, slop in spider gear pin, and ring/pinion seem effected from all the slop - it got rid of some vibrations and a hum I was getting from rear axle)
• Front spider and side gears seemed slightly worn/sloppy so I swapped them out from another Cherokee I have.
• Replaced Transmission Mount (it was torn completely through) it helped muffle it some, but still got vibrations.
• Tried a completely different set of tires (slightly better but stock tires vs. 31's I think was the difference)
• Checked all the front end parts as far as tire rods, ball joints, etc.
• I jacked it up and put it on Jack stands, had vibration still, with no driveshafts it was hard to tell... if there was it nearly disappeared.

Looking at changing engine mounts now, buddy thinks its the rear axle pinion angle (I have not checked but I think on front driveshaft alone it would have disappeared) .... if the mounts don't fix it my next things is the replacing the TransferCase.

I love Jeeps but this one has been the "Jeep from Hell" !!!!!!

Anyone got any ideas? To say I am frustrated at this point is an understatement, I am not usually a parts changer, but that is what I resorted too as any diagnosing has come to a dead end.

Thanks,

Bryan
