Default Differential sludge help.

I just put a new axle in my xj and it has horrible oil sludge. I tried using brake cleaner which worked fine on my 35 but this crap is thick. Any advice on how to get rid of or dissolve this stuff would be very appreciated.

Purple power(?) might work. I would fill the case and mix it around

Ive used Purple Power a ton when i detail cars, the longer it sits the more it gets out. I think Walmart should carry it.

Diesel fuel also works as a cleaner and wont pit the metal bearings like some degreasers.

If you have access to it, an ozzymicrobe cleaner. My dad has one and they're gentle on everything. the microbes actually eat patrolium based stuff like sludge, grease, oil, and crap but doesn't eat paint, plastic, rubber or anything.

Off topic, but I just bought a gallon of PB.

PB worked great. Do I need to wash it out at all though?

Just wipe out what you can and you'll be fine.

A little brake parts cleaner wouldn't hurt.
