Removing diff gaskets. . .any tips or tricks to make it easier???

Do any of you guys have any tips or tricks to make getting diff gaskets off of the diff cover?

I get so tired of sitting there with a razor blade trying to get all of it off. . .I've tried spraying/soaking with de-greaser, wire brushes (haven't tried it with a power tool yet, I'm out of wire wheels), razor blades, even tried 150 grit sandpaper and that didn't work either.

I just finished getting 90% of it off of my D60 front axle and I'm hoping somebody will have a tip to speed up the process on the 14-bolt rear axle.

Thanks!

I usually just use the wire wheel on the grinder lightly. Takes all of 30 seconds.

But using a razor blade isn't too bad.

I use a wire wheel also,i also have a plastic type grinder wheel with little nubs on it,works PERFECT for old gaskets,but i don't where to get them,i've been fortunate enough to have a Millwright give me a box.
In the past if i didn't have a wire wheel,i've used paint stripper and it works wonders,softens the gasket up and scrapes right up.

Try a sharpened putty knife. This usually works well on both the lid and the axle housing.

I use a razor on the diff itself and a wirewheel on the diff cover, stupid easy to get it all off. The wire wheels I use aren't hard enough to really gouge the cover but it takes the RTV off with ease. I've used the plastic nub wheels as well at work and they work really well but they will take away metal from the diff cover, more than the wire wheels would. I was surprised to find this as well.

Try using silicone/adhesive only on the diff cover. The gasket will only be stuck to the cover and can be moved to the bench for removal with a wire brush equipped grinder.

Enjoy!

...a well prepped, well driven, vehicle should do well in any terrain, including the highway.

Carburetors became obsolete during the last century... do what ever it takes to get fuel injection...It makes bigger grins off road.

Thanks guys. . .I figured a wire wheel would work, but I didn't want to damage the sealing surfaces and I was out of wire wheels.

This isn't something I was messing with a ton when I was working on musclecars, but now that I'm in the off-road world I'm thinking that I'm gonna be doing it a LOT more often. Taking the time to do it with a razor blade wasn't too bad when I was only messing with a diff maybe once a year, but any more than that and it's just a waste of time.

I think you can get those plastic nub wheels at Eastwood.

Back from the dead (maybe)..

A buddy told me to stuff some papertowel into the diff itself, to prevent crap from scraping getting in the gears. Wondered if anyone had thoughts.

I do this as its easy and does keep stuff out, although have always wondered realistically what harm would RTV scrapings do if they got in the gears?

Not trying to hijack this tread but honestly it's been dead for a year so what the hell.. I guess I am.

Removing the junk from the differential and noticed some rust was removed and it doesn't look too good. I got that lube locker but is this going to be a problem?
