New Front Diff

[jrod332]

After much troubleshooting. I found out today that my front diff is shot. I was lucky enough to score a new one at a salvage yard for 250. Not a bad deal at all in my book. Only 15,000 miles on it and comes with a 6 month warranty. Just need to get a couple cases of beer and get this thing in. Hopefully goes in without a hitch. I have read that it takes 75-90 synthetic fluid. Anyone know if thats right? And how much? Until it comes out the fill hole?

you made sure the gear ratios match right?

I was just getting ready to post the same thing till I scrolled down Better make sure there the same ratio before you bolt everything in or you will look like this if its not.

oh i triple checked, believe me i would not want to go through all that to find out it was wrong. I double checked the rpo in my glove box even though i knew it was 3.42. My friend at the shop I go to called the salvage yard to make sure and I checked it again when i went to pick it up.
