Question Axle ID'ing

1988 FSB 4X4 auto w\OD 302FI

I need to replace my front shocks, quad shock set-up. Shox are decided by what front axle I have. I have limited slip, but I need to know if it is Dana 44, 50, 60. Can't find anything obvious. Before I buy the shox can someone give me a clue to ID the front? Thanks!

Question Thanks Kemical

Just what I needed! Thanks! So is the rear a 44, 50 or 60? My Dodge PW had a 60 rear, 50 front. Just wondering. Sorry, did I say the D word?

My family knows, when I go, I want them to bury me with the Bronco!

An 8.8" huh, I'll scribble it down somewhere. Thanks!

was the 9" rear an option on the bronco?

the ford 8.8 is an 8.8" ring gear. That axle was run in lots of vehicles in different forms including mustangs. The rear cover has 10bolts holding it on the diff housing. The other truck axle was the 9" but im not sure if it was in the broncos, i think it was an option but im not sure. the ford 9" has a removable carrier, so no rear cover. thats a real easy way to tell. You unbolt the carrier from the drive shaft side and makes for quick gear changes.

Its such a common swap that they probably just ask out of habit.

My 85 has a 9", I think most of your pre 86 broncos had a 9" with a few of the later ones having the 8.8" then 86 and up was the other way with most of the broncos having the 8.8" and the 9" as an option.

This is not correct. For one, Broncos came out in 1978, not 77.5. The 9" axle was developed much earlier than 1977, and was used in trucks and Broncos as late as 1986, and was phased out by the 8.8" starting in 1983.
