The spider gears are loose in the diff..
99xj almost 200k miles.
The gears on the cross shaft are loose, side gears appear to be ok.
I was just wandering where to buy, local, the thrust washer/spacer to install behind the spider gears. Part# and stores would be awesome or any info..
Figure do a fluid change and general maintenance while i have a spare vehicle for the week.
Have a whine noise above 40mph and wouldn't mind spending the 20$ or so to see if it fixes it. I found spider kits, but not wanting to spend the 80+$ for spider gears.. Maybe its the pinion bearing but would rather swap in a 8.25 or 8.8 before going that far into it. Rear diff swap is in the future.
Ring and pinion appear to have good contact pattern, and appearance of spidergears look good (no damage or chips)
The gears are loose as in the gear can move side to side on the shaft, maybe 1/8"or more. Also up and down on shaft.
If you want, several youtube vids on the d35 spider gears are out. Mine looking the same.
Loud whine any time im pushing the accel, 35+,mph..
It's been loud.since i bought the jeep.. Almost 100k miles ago.
Im certain its the pinion. No leaks, change fluid seasonally..
Abs will be taken care of, looking to go to disks if i do the swap.
I've been waiting (wanting) for the rear to blow, but it's holding on for a long time now..
If you go 8.25 you can use the disc brakes of off s zj d35. Easy upgrade.
I have 3 xjs all with 8.8's. $300 to have them welded professionally. That's including the axle price. I've never looked back since.
