Rear Hub Seal

[Jock The Rock]

Gday

I'm just about to embark on replacing my rear inner hub seal in the Defender.

Defender=1st was going to give me a hand but I doubt he's out of bed yet :o :D

So I thought I would make a start

Does anyone have any tips or tricks?

I have a couple of Workshop Manuals so hopefully they will help

Thanks

chock it
jack it
clamp the brake line hose
remove the wheel
remove the flange dust boot
remove the caliper
undo the flange bolts
remove the flange
remove the bearing retaining nuts
pull the hub (carefull not to get dust in it)
hoik the seal


work your way backwards up the list substituting install/replace and donf forget to bleed the brakes.

easy.

Thanks Dave :)

Probably a stupid question but how do I clamp a brake hose?

EDIT: Dont worry worked it out

There is a correct pinch off clamp that has rounded edges to the "jaws" so the hose is not damaged, but you can use locking multigrips or a small G-clamp with some short 1/2"rod pieces fitted in before you clamp it up to round the edges off.

Unless you are a Fridgie, in which case you'd probably have a refrigeration pinch off tool in your box.:D

Am I right to wash this off with petrol?

And another thing, will I need to put new rear pads in, because one is coated in oil?

Thanks

Petrol is great for cleaning. Just make sure none of the grime gets washed into the stub where the axle comes out. And yes I would replace the rear pads. Once oil gets onto them they are never as good even if you clean it all of with petrol or brakekleen. small price for good reliable brakes. Must have been leaking for some time to have that amount of oil/muck spread around.....Brian

definitely put near rear pads in. The only other thing i can recommend is taking the stub axle off pulling the axle oils seal out of the diff housing and putting the stub axle back on, put a bit more diff oil into your diff housing and run your bearings on oil instead of grease. I did that in the back of the disco and havent had to touch them since. They probably are due for a check now, will do that soon, but its much better. You just need to make sure your hub seal seals well on the stub axles so it doesnt leak the oil. matt

Well it's all done :) sort of. Bit of bad news about the stub axle which is a bit pitted so thats why the seal probably went.

And then the diff pinion seal is leaking as well, and the swivel housing is leaking too :mad:

Thanks for that

I'll order myself a new set

It's running Maxi-drive axles and flanges so they are already converted to run in oil. I think you have also answered my other question which is where to top up the bearing oil. In the front there are the filling and drain plugs, but nothing like that in the rear.Does it just run straight from the diff oil to the bearings?

Also does anyone have any idea what grade of oil to use in the rear diff?

Thanks

[Jock The Rock]

Just one thing I want to check before I drop it off the chocks.

Am I right to just stick the wheel back on a drive off? Will the oil run from the diff into the bearings or will I need to top up the hub individually?

Thanks

EDIT: Thought I might speed up the oil flowing into the hub :)

personally I pack the bearings in grease regardess on if they are going to be oil filled or not.

80/90 oil is what your after for the diff.

yep new pads.

yep wash in petrol.
