The factory R180 out of my z (it has a non-LSD R200 in it) is absolutely caked with grime. Is there a specific method and/or cleaner that's best for getting all that off? Can the whole assembly be dunked in a bucket full of solvent? Perhaps I could have it hot-tanked?

My first thought is a parts washer and wire brushes to get the gunk off.

How about... wait for it... Gunk.

You can put the diff in a parts washer or a solvent tank, but if you submerge it you'll get solvent in the oil. Not sure what effect the solvent will have on the seals either if that matters. I put my bare housing in my solvent tank and cleaned it that way before reassembly, worked great.

Simple green and a scrub brush will work. It just takes time.

Wire brush, brake cleaner or acetone and a little elbow grease and time always worked for me.

Rinse off and a fresh coat of paint and you'll forget how crappy it looked before.

I had a couple cans of carb cleaner sitting on a shelf, so used that with a bbq grill brush. Worked like a charm.

Ya, there is more than one way to clean your rear-end...

Actually, I was thinking that you have to be careful. If you scrub your rear end too hard with a wire brush, it might keep you from being able to drive your Z.

Ya, NOW you tell me...... :stupid:

Soap and hot water, pressure washer works good. Light enough to bring to a car wash if you dont have these items! Easiest part on the car to clean, IMHO.

As others have stated, no solvent tank!

If its that dirty you might as well pull the rear cover and clean inside the diff.
