BEFORE





AFTER
this is wat was left afther just cleaning the obvious rust




the diffe was literaly caked in with rust, took about whole can of pb to remove it, and most of its still there

\

 

I actually just finished doing my frame. All i did was go over it with a wire brush a few times to knock off most of the rust. Then i used rubberized coating on it. It cost about $10 a can.

 

A new rear diff cover is about $15, plus the cost of the replacing the gear oil. Just FYI for future reference.

EDIT: Sorry and a new gasket, but most covers come with one.

 

actually i planned on one lol, just wanst sure how much it was
how do you add oil? like when i added the new cover, how do i put new oil in
?

 

There should be a plug on the front side of the differential that takes a large allen key to remove and then you fill it there!!

 

Negative. It's a square drive hole. The 1/4' drive extension from any socket set works fantastically if I remember the size right.

 

Rust is not my friend! I cut it out and welded in new panels. Make sure that you seal your work right away or it will rust fast.

The rear diff plug can be removed with a 3/8" ratchet and short extention.

Ahhh 3/8. Couldn't remember the size. Thanks Chevy Lover! And I really need to learn to weld...that looks great!

 

woah Ineed toget a tetnus shot just looking at these pics! have you looked into soda blasting?

 

Yeah I did mine, too. you might want to look into the rear differential cover. I know of 2 ppl and me that theirs rusted through. For future reference, I would be sure that your fill plug will come out ok, I broke a snap-on extension off in mine and couldn't get it back out. I ended up tapping a hole in the new cover(After it was installed, which is why I say check the fill plug first, much easier to do if the cover is on a bench) and installed my own fill plug. It is at the same level as the original. My blazer came out of Ohio, down here I really don't have to worry about rust unless I go to the beach alot. Oh! and I could only find a cover at the dealer. I think it was around $20
