Review on LubeLocker Dana Differential Cover Gasket by Greg Sullivan

If you use this and notice a leak before you can apply some of your favorite gasket glue and be sure. I cleaned and scraped thoroughly, but what if there was a leak before the cover could be flexed? Another 1 star user made it clear that the shim seal is broken halfway through the shim in their ad. Mine didn't leak on city streets at 35mph for a few days, but as soon as I hit the freeway it started leaking. I'll delete/look at this theory and get back to you.
