    I have one, don't know if it has done anything. I will say the aluminum covers do not have a magnet to catch shavings like the stock one does. Why is this important? The bearings on our axles do not have races so they ride directly on the axle. If and when the axle burrs you won't be able to reuse the original axle since the axle is no longer a smooth surface. Probably prolongs it short term, don't see it helping a daily driver. Not really a straightforward answer huh?

    Some Rear end covers claim to "help" the rear end, but adding cooling fins, some have studs for pre-loading the bearings and some hold additional fluid, over all they just look cool, dont expect them to save your stock ten bolt.

    ^^ Agree. The 10 bolt simply has inherent weaknesses that a cover will not correct. That being said, it certainly will not hurt anything to install an aftermarket aluminum cover.

    I have one. They make changing the rear gear oil easier. They aren't going to keep a 10 bolt from blowing though.

    Very true- I have a really nice Moser one and now I'm looking at replacing my rear. Also have bearing cap studs and they obviously didn't help much either.

    Not quite. When I unbolted my drain plug (after 500 miles) it pulled the threads out with it. Thank you Moser.

    Wow. I pulled the drain plug out of mine yesterday and the only problem I had was the drain hole is so small it takes 15 mins to drain! It's real important on those plugs to use some teflon tape on the threads because the metal that the bolt is made of is not aluminum and can sieze up in the threads.

    I used thread paste after drilling and cutting new threads. The plug was factory installed by Moser and I simply made sure it was snug before installing the cover -- never removed it until 2 weeks ago when I tried to drain the fluid.

    Did you call Moser? Not sure how supportive the'll be...

    I did the same exact thing with a Summit cover I had years ago on my '70 Nova (on a 8.5" corpo 10 bolt). If you cursed half as much as I did, I know it couldn't have been good!

    I was able to fix it. Not worth the hassle to chew someone out on the phone and get nothing in return. Plus, I get to argue all day long at the office -- not something I want to do in my free time.
