Rear Ring and Pinion '98 TSi

I BELIEVE I've got the Dana 35 with 3.55 gear ratio (will have to call the dealer and verify this with the VIN). The pinion has pretty bad play in it (I can wiggle it by grabbing the drive shaft) and it howls on decel. I've opened the cover and confirmed this by the wear pattern on the ring gear. Had a good amount of metal shavings in the fluid. I put the cover back on and filled it with fresh gear oil. Now just trying to decide what route I need to take to rectify the situation.

Should I change the ring and pinion gears (along with all required bearings and seals)? Or can I get away with changing the bearing kit on the pinion?

AND does the pinion have a crush sleeve or will it need shimmed? I cannot find clear answers on this.

Thanks in advance for any input you guys have!!!

The axle needs a full rebuild including ring & pinion and master rebuild kit. I would also replace the spider and side gears.

Sounds pretty rough. It may be a cheaper route to find a complete replacement axle instead of replacing your internals

Thanks for the replies guys. I called a friend who runs his own shop. We are weighing out rebuild vs installing a whole used unit. I left a message with the best axle guy in town for a quote on a rebuild, and my buddy is going to search his suppliers for a used axle assembly. I think the rebuild will come in cheaper. On my old XJ, I had a quote for a TOTAL rebuild AND trac-lok upgrade come in at around $900 or so. I am not going to upgrade the rear on the ZJ, just want it on the road to get some more life out of it until I can get my situation in order and get a better vehicle for work use. As this ZJ is strictly a work and ****ty weather vehicle.

Thanks again guys.

For a project vehicle a total rebuild is definitely the way to go. If you are just trying to extend the life a little then rolling the dice on a junkyard axle should be cheaper. These axles can often be had for $200 or even less. Bolt it in. Drive.

^ this. A pain to pull yourself for sure, but it's probably the most economical way.

I've found a used axle assembly that I am going to buy for $275. It's got a 90 day guarantee... I should know by then if it's going to be trouble.

Speaking as a first timer{and a last timer hopefully} it wasn't one of my favorite things to do. If a salt belt vehicle it might be a bit tougher than mine was.It wasn't a balls to the wall pain,but it wasn't particulary enjoyable.

I'll be using an air impact gun and breaker bars. Shouldn't be too bad. I'll also get Seafoam's penetrating oil, it's probably the best stuff out there. Really, the job doesn't look TOO bad. I am preparing to have to replace brake lines...

Before going on a full-on rebuild, try resetting the pinion bearing preload and possibly changing the crush sleeve/pinion nut/pinion seal.

This had magically saved my front axle, which was starting to whine around 60 mph.

Second cheaper option would be junkyard axle with changeover warranty, $100-200 on most junkyards.
