today I made a junk yard run, came home with a ford 8.8 disc brake, 3.73 posi rear axle complete.. price $ 250.00
it came out of an 97 mountianeer. i havent got a chance to check it out in detail yet but it looks pretty good.
I did find out that these ferds have axle codes on the drivers door, makes it easy to find the right one without having to spend time jacking the thing up just to find out its not what you want... from what i learned today the posi units use a letter and a number on the code tag, the one i got was coded D4 ..... the other axles seem to use just numbers, i seen a lot of 42 codes, ... after i found one that i thought was correct ,the guys at the yard picked up the car with the big fork lift ,and on the diff cover there is a tag..
on the bottom line , up close to the bolt that holds it on is the id for the axle,,, it reads ,.....3 L 7 3 ...."L" indicates the posi... 3. 7 3 is the ratio . pretty easy to ID actually..... there is also a tag for the lube type on the housing too. the non posi units i saw only had one tag.... this is just what i learned by pokin around ,it may not be correct 100 % .... the disc brake units seem to be 1995 and newer. 1994 and older are drum brakes , the codes seem to be the same for both.. I found a lot of drum brake units, must have been 5 or 6 of them out of about 20-25 cars..seem to be pretty common.
i got to borrow a digi camera ,,, so i will post photos and more info asap.... hope you guys can use this info......Ron
