    Hi, 1st post on the forum.
    I have a 2002 with a leaking rear differential cover plate. Since these are welded on, what are folks using as a replacement cover or fix ?
    As my plan is to cut the bad one away and reweld a replacement cover back on.
    I don't imagine anyone makes a kit for this application.
    Like to hear what others have done. Thank you.

    How is the plate leaking? Did it get damaged? How do you know it's not from the drain plug or the vent or so? I mean, it's possible these things could leak...but something else doesn't sound right.

    These cover plates are/were made out of cheap steel (like the frames) and simply rot away in the northern climates. and yes breather holes do get plugged along with weld spots for E brake holder etc invite corrosion. They really are too thin for welding as you chase pin holes around them. Some guys try epoxy but with limited success.

    OK, got it, it's rusted. Yeah, just weld a new cover on. You can buy covers.
