The rear end cover on my 03 is "sweating" after only 13,000 miles. I thought of taking it in to get warranteed but decided that it's easy enough to just fix it myself. My questions are 1-do I need to use friction modifier? And 2-does anyone know what size threads are the bolts that hold the cover on? I just wanna reseal it with RTV and replace the fluid while I'm at it. I'd like to know the size of those threads because I want to make 2 alignment studs so that when the cover goes back on, I get it lined up perfect the first time. Thanks.

 

I understand about not wanting to take it in, rear end cover is a snap - yes, the fluid will need the additive, I used high-temp RTV on mine (it was just laying around waiting to be used up). Don't remember the bolt size, but it was common. Used a pump to put the new fluid in.
Wish all of the maintenance stuff was this easy (like spark plugs?).

Oh forgot, I just used 2 bolts in opposite positions (9 & 3 o'clock) and it lined up perfectly.

Thanks for the reply......did you put any RTV or anything else on the threads? I don't think it is necessary as I have never done that before but I thought I once heard someone say to use thread sealer. I dunno. Don't think so.

 

RTV on the threads

Do you mean Lok Tite??

RTV is a liquid gasket maker........it's for sealing the diff housing and diff cover.
