oil seal & reversing lights

[snowbound]

It's me again, I seem to be asking more questions than a paranoid cop this week, however my "new" RRC has just gone in for rego inspection.
First question, there is an oil leak on the driver side rear back axial depositing oil on the brake pads. How hard are these to do and is it a DIY job or one for the pro's?

2nd question, my reversing lights aren't working. Globes OK, what is the common cause for this. Its an Auto BTW. I've not had a chance to check for a blown fuse, but I couldn't get that lucky!, in any case fuses don't blow for nothing either! No wires hanging that I could see while it was on the hoist. Any ideas folks??

Thanks!

The leak is a nice easy one to do but check the diff breather is clear first I had trouble with this in the past and found it to be a common problem if its the actual hub seal leaking RTC3511 is the seal to fit and there fitted 5 mm below the face of the hub

The Oil could also be the Swivel Housing Seals. Very common.
A not so easy to do job, if you're not confident.
Reverse Lights: I'm gunna say the switch!:)
