80 series rear axle seals gone.

[bruiser]

As above the rear seals are gone on my 80 series and i have diff oil coming out behind the wheels.

How hard is it to replace these and do i need any speacial tools?

How long would it take to replace them as well as the bearings?
Thanks

inner axle seal, and outer axle seal around 30 mins to do both sides

wheel bearings, add a press and about another 1.5hrs per side.

Remove the road wheels, and then in order to complete the repair as required you need two 8mmx1.25x25mm bolts to remove the rear axles. After loosening the 10mm bolts on the hub flange give the end of the stud a tap to loosen the cone washers. These can be difficult to remove and putting a little grease on them during reassembly will aid you if they require removal another time. The 8mmx1.25 bolts screw into the holes in the hub flange and the axles comes out fairly esaily. After this you will have a large lock nut with three lugs on it. You unscrew the two phillips head locking screws (sometimes very tight) and then unscrew the lock nut. After removing the brake caliper retaining bolts (17mm) the hub will come off with bearings etc. As the 80series is a fully floating rear axle no press is required to remove and replace the bearings.
The whole job is approximately is 3-4 hrs for both sides including replacing and repacking the bearings and seals. If the bearings have been immersed in diff oil for a while the hardening may have gone and the bearings should be replaced.

If the bearings have been immersed in diff oil for a while the hardening may have gone and the bearings should be replaced.

This caught my eye .. are you saying the hardening may have gone die to the bearing getting hot due to running in oil instead of grease ?

(I have heard some wacky stories about some doing all sorts of crazy things to metals in the past)

Couple of points...
* no press reqd for toyota...thats a Nissan requirement.
* oil in polymer is called grease...some heavy duty wheel bearings use oil as std, like semitrailers...
* Go to sbs bearings and buy a kit...comes with inner axle seal, and inner hub seal, plus some handy locking tabs and gaskets for the front as spares...
* I bet your diff breather is blocked, or both sets of bearings are loose or worn...as this is a very unusual occurance...new brake pads on the back would be a good idea if oil got anywhere near them...

ahh, yeah, you can just hammer the bearing seats back into the hub, i never used a press, but i never do, you can use one though

I would also wear safety glasses when hammering the old bearing seats back in, as a mate of mine copped a piece of metal in his face from doing that once.

Buy yourself a bearing cone drift, then you can hammer it or press it to your hearts content....i bet you hammer the seal in thou.....
