Roush Diff Cover Girdle Issue

gsjohnson · November 8th, 2007, 09:03 AM

I installed a Roush rearend girdle cover a couple of months ago and it continues to leak gear oil. It appears to be leaking thru the holes for the support screws that go thru the cover. I then sized up a couple of copper washers and installed them underneath the jam nuts on each side. Still no luck, it still leaks. Anyone have any experience with these and have a remedy to cure the leaks? Thanks in advance.

Anyone?

did you torque them down correctly. is it used. maybe just use some gasket glue.

sounds like a bad gasket.

you need to pull the cover and make a new gasket.

didnt know their was a gasket on the support bolts?

it's supposed to be around the entire diff plate.
it was probably tightened down wrong.

you need to let the gasket get tacky before you hand tighten it.
then wait another half hour or so before you break out your ratchet set.

im confused??

i thought he said it was leaking through the suport bolts?

how would the diff gasket cause that?

unless I am mistaken I believe that he is talking about the bolts that "bolt" the diff cover in place.

the only other holes i could think of are the drain/fill plugs or the rear seal.

i think hes talking about the bolts that preload your maincaps. its a diff girdle not just a diff cover

mattstang · November 9th, 2007, 09:35 PM

no its a roush one stupid

It is a Roush unit and it is leaking thru the girdle support studs that go thru the cover. The cover gasket is not what's leaking. Yes, it is torqued properly. It is just bleeding thru the holes slightly. It is similar to the one in the pic except the studs/bolts are not counter sunk.
