I am going to be doing some work on my rear end, I went under it to see if I could get any info to help my identify the rear end with no luck. I then looked at a parts mag. that shows most of the rear ends from Ford and others and my bolt pattern does not match up to what I though i had (8.8). I could not find the bolt pattern that I have, so is there anyone out there that can help.
ok this tells me that my ratio is a 3.55 but i still dont know what rear end i have. Through the site you gave me, I still cant match up the bolt pattern to know what type of rear end i have. it did show a 9.75 for 97 and up expeditions but the bolt pattern is way off from what I have.
My bolt pattern matches up the the 9 but that actual rear end was not used unless i read some wrong info.
ok, thanks for the replies and help. Its nice to know what rear end i have, how is the 3.55 anyways, I mean where does it stand among other common ratios. I hear alot about a 4.10, 3.73 and a few others.
