The rear-axle hub seals appear to be leaking. 1995 Discovery with ABS. My question is what tools are needed to do this job, and what parts are required. The truck has 134,000 kms on the clock.

 

1. Check banjo bolt on the axle that has a line that runs out of it forward to vent the fumes that evaporate from the diff oil. Bolt can get full of mud like mine did (too much wading I guess), and pressure can make seals leak. Bolt has holes drilled in the threaded area.

2. If doing the seals go ahead and do wheel bearings.

 

Check the axle breather first, if it is clogged it will cause leaks.
It is a small hole and it clogs easily with rust.
Take it off, take it apart, reem it out with a drill bit by hand, clean it with carb cleaner and put it back.
See if the leak goes away, if not you will need new seals.
Here is a kit, your not in the US so you cant buy the kit but it will list all the parts needed.
Make sure you do both sides.

Pix of what to expect

 

And it can also be leaking because the seal has failed, when was the last time you cleaned, inspected, replace the wheel bearings and seals, probably way past due. This should be done every 20,000 to 30,000 miles depending on the type of wheeling you do.

 

Thanks for the quick replies, everyone!

I recently bought the truck, so I don't know the history of the repairs/maintenance.

I pulled the wheel off the truck and to my horror realised that the axle bolts were all loose! Looks like the last mechanic that had done the bearings didn't torque the bolts up.
