Whilst I was checking out the site of the busted rear O/S spring earlier today,I noticed quite a build up of oil on the rear diff.

Now having the rear diff pinion seal fail on my previous Elite I knew the area wasnt the same here as oil was only on the bottom part of the diff body/cover plate and slight marks around the drive shaft entry points.

As I need to drop the diff to remove/replace springs I intended removing the cover plate and renewing the diff oil as I half way there anyway and have diff oil etc from previous job.

Is it only really likely to be a failing seal on the cover plate causing this oil sepage or do the drive shaft seals fail
albeit the pattern of the oil leads me to believe its comimg from the bottom.Its definitly not rear pinion seal though

Why do you need to remove the diff to replace the springs??

Why do you need to remove the diff to replace the springs??

You don't, you lower it slightly on the mounting bolts so you can get enough clearance to get the springs out. Not usually a problem with lowering springs.

I see... Its my intention to change shocks and springs this Friday and wasn't aware of slackening off anything else.

Ensure that you can undo the filler plug before removing the diff cover!

Good point..are they normally Ubber tight ?

It just seemed like a good time to do abit of preventitive treatment whilst I was in that area.

Re oil leak...do the drive shaft seals fail ??
