thanx for posting this... I really need to do this myself, when I bought my Dakota the rear Dif. plug was MISSING! but the guy I bought it from said it had to have been recent, so I made a a new plug out of a different type of plug, (which is actually more effective than the original) right after I bought it, but was unable to properly top up the oil because of how thick the stuff is.

It's really in order for a dif. oil change IMO I just haven't done it yet because of the gasket, but what is this "mold-a-gasket stuff"?

 

It's a tube of black RTV silicone "gasket maker" you can get at any autoparts store. It does a much better job than the pre-molded gasket you can buy and is a lot cheaper.

 

sweet that will be the next thing i do... thank god for this forum!

 

hate to bring up antique threads.....but thank goodness for google.
anyway, the 'black stuff' or how about permatex sensor safe blue rtv silicone gasket maker for the rear diff cover on my 98 D?

 

Usually I'll use a premade gasket AND the RTV. But RTV blue will work just fine as well.

 

Thanks for bringing up this thread!! I am going to do this now too. lol I didn't know the black silicone would work well.

 

nice maple leaves......oh. whoops. what was my question. glad i brought up this thread now, too. oh yeah, thanks!

while on the subject, is there any retro-fit replacement for that stupid rubber plug???? checked out aftermarket diff covers, but i'm not spending 3 hundred bucks to get a cover that uses a bolt/plug.....

 

Ya I like Maple Leafs too

You only need a new rubber plug? Have you tried Napa, AutoZone, Dodge, or a junk yard?

 

Question, how many liters does the rear hold? I have about 5 of the 1 liter bottles of SAE 80W-90 GL-5 High Performance so that should do?

 

According to the FAQ "Rear Axle: 7-1/4" 1.4L, 8-1/4" 2.1L "
