  • Rear axle maintenance / oil seals / bearings replacement

    Hi all,

    I've had a rather loud clanging sound when going over bumps coming somewhere from the rear right for quite a while... When I finally decided to have a look at the virtually non-working hand brake (I've always been able to find some rocks to put under the wheels when parking on a hill so I didn't think it was that important ) things started to make sense.

    First of all, it was clear why the hand brake didn't work.
    a bit worn..

    But I also noticed that the two brake shoes were moving front to back freely, so that also explained the clanging I'd been experiencing! Removing the brake shoes revealed a bit of damage
    loose ring in rear axle assembly
    I'm trying to figure out what this loose ring is to order a replacement (red circled in above picture). From the parts diagram I got it appears to me that the "brake drum oil deflector" has split in two, probably because that hand brake shoe was rattling around in there, banging on stuff.

    I'd be curious to hear anyone else's opinion on this?
    Also, how hard would it be to replace that brake drum oil deflector and the axle oil seal?

    It looks like I'd have to remove the axle bearing, assuming I'd need to use a press? Could I reuse the old bearing when putting it back toghether?

    Thanks for any advice!

    I found the workshop manual for my prado and according to that every part except for the oil deflector is non-reusable. That would include the bearing assembly which goes for about $150 each, best price I found. Essentially if I disassemble the axle shaft to replace the oil deflector, I would also have to replace axle bearing inner retainer, washer, hub and bearing assembly, ... That seems a bit over the top. I don't know if that's just Toyota being pedantic or if the bearing assembly really might take damage when removing with a press..?

    I think for now I'll just replace the rear axle oil seal and o-ring. The workshop manual diagram suggests I should be able to do that by just unbolting and removing the rear axle shaft (with parking brake plate).

    This thread for the 120 seems to suggest otherwise though. But according to my workshop manual the Prado has a setup like the FJ Cruiser and the procedure should be pretty much exactly like shown in this video. Any thoughts?
