99 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.
