Hello, I have done quite a bit of research and performed quite a bit of maintenance to my 1999 Jeep cherokee 4x4 but cannot narrow down the vibration. I have a 4.5" Rusty's lift on 33x12.5" TA's. Recently replaced were both front hub assemblies and both front axle U joints and trans mount. I also had a laser alignment at a local 4x4 shop. They were the ones who told me to replace the hubs/U joints and that was what was causing the vibrations.
Jeep STILL has vibrations from 15-35mph and strongest right around 25mph. It is also ONLY under load that the vibs occur. On deceleration (let completely off gas pedal) there is an on and off grinding noise from transfer case area. Anyone w/ these similar problems out there? My next guess is SYE.
Any help would be appreciated, Thanks.
