Leaking rear transaxle seal

[KeithK]

So i had to pull right wheel to replace battery. When I did I noticed the large nut and inside of rim had oil. Brake drum and shoes are completely dry so I am assuming transaxle seals? Concur? I'll take pics tomorrow if needed.

Could be if it's a Swing axle? Not sure how the outer castle, ("large") nut would/could be wet?

Master cyl. still full?

Pics will help...

Here is the right side axle and inner axle.

I would say your axle nut is loose. The torque on nut should be 260 ft. lbs. When torque in gone, transaxle oil seeps out past seals in brake drum. There is a factory weep hole in bearing cover that allows oil to drain out backing plate so brake shows don't get wet. "Keep-On-Triken" Dick

The nut was hand loose when I took it off, Thank you.

Dick has it exactly right.

Just tightening the nut might not be enough though.

There is an o-ring around the axle behind that spacer that the seal contacts.

If that o-ring is not compressed right it will leak down the axle. If run loose it will likely damage the o-ring and not seal until replaced.

If/when you replace that o-ring make sure it fits the chamfer on the spacer correctly. I have had a hard time with not having the correct crush on that o-ring.
