Œ99 A-6Q 75K miles on it.

I'm just back from shop after getting t-belt, t-stat, Water pump, and other
rolling belt parts replaced.
While the car was up on the lift, the shop owner showed me where the car
picked up a minor leak at the transmission output shaft seal. I went to the
rear differential and noted leaks there also, from all three shafts: the
axle seals, and the ring and pinion seal.

Is this common?

Nothing looks catastrophic, and fluid levels are ok for now. But I¹ll be
putting it in at the next oil change for this repair. It looks like most of
the exhaust system will have to be pulled, just to get to the drive shaft.
There is some corrosion on all exhaust plumbing, I drive this thing in snow
quite a lot, and I¹m wondering if there are any surprises waiting when they
pull all this to access the drive shaft.
Thanks,

Grover

 

Common? Well, lets just say I stock all those seals. Pinion seals
are rare, but I've replaced a few. On the front transmission output
seal, the leak is rarley the seal itself. There is a cover on the
back of the box, above the output shaft, it goes on with two screws.
Remove it, clean it, and use a decent anerobic sealer (Loctite 574,
Porsche case sealant, works great.) to seal it up. If you replace
just the seal, the leak will persist. And it stinks, it drops right
on the cat.
At 75K, make sure you have him check the front arms thoroughly as
well. They usually don't make it this far.

Great heads-up on including the cover on the front box.

I'll relay that request to my local guy when I take it back in for this job.

All three rear shaft leaks looked nearly equal. I took that to point toward
"normal" wear than outright failure of a seal. The front was a bit worse,
with some pooling evident - certainly enough to give Fluffy's fur a hot oil
treatment.

Thanks again,

Grover

Thanks,

The front box does form a drip (sort of ready to, but not quite). Though, I
haven't noticed any on the ground.

I'm going to go to my next oil change for sure, and then likely have both
front and back done - since the exhaust plumbing will have to be yanked
regardless.

In the mean time, I'll keep a close watch on my parking spot.

If it isn't dripping on the ground then don't worry yet!
