Hola! My son and I just replaced the pads and rotors on his wife's 99 4runner 4x4 w/ 3.4. The dealer told my daughter-inlaw that she needed new rotors (she didn't) along w/ new pads (getting close). I was given this info long distance and they came down for the weekend. Then I was t0ld that the dealer told her her rear axle shaft was leaking. I pulled the drum, and yes it was leaking. Azone didn't carry the seal but Advance Auto (similar) did when I was asked whether it was the inner or outer seals. Is there inner/outer? can I get aftermarket seals? Is it similar to replacing the front wheel bearing seals on an 89 toy 4x4? I replaced the seals on my truck (89) when I replaced the bearings/races in the rear axle. I've never dealt w/ abs but her 4runner has it. Do I have to worry about something SPRINGING out when I remove the abs sensor at the rear axle? Thank you for any infor.
ps I saw a guy at Azone w/ an 84 toy pickup 4x4 w/ a diesel. He's making his own bio-diesel.

 

Inner seal, I believe. Pulls out, tap in a new one in. Most suggest OEM, they aren't expensive. Nothing springs out.
Check for clogged breather and bad bearings while you're at it.

 

Thank you Habanero. Can the shoes be cleaned w/ degreaser and reused or will they have to be replaced along w/ the other side? The shoes show very little wear. Thanks!

 

I was able to degrease shoes and drum, the seal hadn't been leaking long, but definitely had to use some brake clean on 'em.

If they're sticking you might not be able to save them.
