I have a 98 xj, lifted inches in rear, 5 inches or so in front, RC longarms, 231 with brand new AA SYE, 8.25 open 4.56 gears. Brand new motor mounts and transfer mount. Angle is 1 degree below output. Measured who knows how many times.
At one point I thought the RC crossmember was not aligned properly based on the trans mount I was using. I slotted the mounting holes in the mount, and aligned the pinion perfectly with the output shaft.
I installed the gears about 20k ago. There is no play in the pinions, gears are quiet, no metal in oil, nothing obviously wrong with them.
I have smooth running nitto terra grapplers(road tires) in about a 33 inch size.
Front shaft is not installed.
Originally was using stock front shaft in rear. Vibes.
Totally rebuilt shaft, and had balanced at Driveshaft service Oxnard. They said the slip joint was fine. Still vibes.
Had it re-balanced. Still vibes
Ordered a brand new Tom woods shaft with the long spline. Better, but still vibes.
I have read and re-read every thread on this subject over the past few months(even some posts where I think I know what I am talking about, but obviously don't).
Anybody around Ventura county have a shop they trust that can take a look at this? I am just tired and frustrated with it.
Vibes are felt above about 55 mph in drive or overdrive
Don't seem to vary depending on accel, decel, cruise or coast.
Front axle shaft ujoints are good, one is new other is smooth.
Rear Wheel bearings are new, front are tight.
Hoping for a shop recommendation or somebody that may have some time to give me a second set of eyes on this thing.
Thanks much,
Mark
