I don't know what info you're after but the gear ratio is 2.75 I think. What is it out of??

[crawlinTJ]

Does anyone know what type of 9" housing this is, big or small bearing?



Thanks.

I don't know what it is out of, I would like to try to find out. I am wanting to narrow this.

I don't know whether it would be helpful or not, but the information I was able to collect about the Ford 9" rear axle I've put up on my 9" swap page (I replaced the 8.8 in my 89 Bronco with a 9".) Mabye some of the information there will help you.

Anyone have any idea if this is a big bearing axle or not???

Measure the bolt spacing on the flange. If it's 2 3/8" center to center on the short side and 3 1/2" on the long side, it's the big bearing version.

What about the bolt size????

[bsoder]

of the three sizes, both the larger two generally use 1/2" bolts. I've heard of an odd duck or two tho, where it's the big bearing pattern but uses the 7/16" bolts. Seems like they made almost every conceivable combination at some point... <IMG SRC="smilies/frown.gif" border="0"> Makes it kinda difficult.

Anyway, if yours has that pattern and 1/2" bolts you're good. If it has that pattern and the smaller bolts, I believe you can just drill them out to 1/2" and it's otherwise identical. I can't say that for abosolute certain tho, this is all just what I picked up while working on my own swap.

Thanks, I have got 2 housings one from a 77 EB that is for sure a big bearing(1/2" bolts) but it is too narrow, the 2nd housing I picked up from a friend, It said 78 Ford Van, F150 on it . The axle tubes look the same as the EB housing, the flanges are the same, the bolts though are smaller. That is what has me puzzled.

if your gonna narrow it, it wont matter as you can buy big bearing ends to weld on from summit

[bsoder]

Be careful... from what I found out, there's a difference between the 9"s that came under the E-150 vans vs the ones that came under the F-150 or Bronco. Apparently the spring mounts are in a different place (may not matter) but also the van diff is offset, where the truck diff is centered.

Just worth checking.

But if I am narrowing it, I can center the diff. Also this is for a TJ so I have to weld on new brackets anyway????
Thanks

Yeah, I'd guess you'll be fine. Are you narrowing it yourself, or having the work done?

I am having the work done by someone at a Race shop who specializes in 9". Thanks for your help!!

Sure, no problem. Take pictures when you get it back, I'd like to see how it comes out.

I will do that, I have reading alot lately about full width axles? With 6" of suspension lift and a 1 inch body. Would it be wise to go wider than stock, if so what would be a good axle to swap in to the front of a TJ?

You're getting into stuff I don't know about, since my truck is a fullsize - I already have full width axles. <IMG SRC="smilies/smile.gif" border="0"> My gut tells me that with a chunk of lift like you have, having wider axles would be a good thing... You could use the same axles I'm running, a 9" rear and D44 solid in the front, both from a 78-79 fullsize Bronco.
