9" rear end

[broncobenny]

If you tried to roll a rear end and the wheels had to turn the same direction together and you were unable to roll one forward and one backwards, what would your first thought be??

 

[S_bolt19]

If I am reading you right, you have the rear end up on jacks and you spin one tire and both spin the same way. Correct? If this is the case, then you have a limited slip, locked or positraction rear end. An open differential will have the tires spinning in opposite direction when you do this.

Thanks S bolt, that's what I'm thinking. It came off a donor EB and was believed to be a standard 9" from a 302, AT. I'm not familiar enough, would there be any markings on the 3rd member?? I didn't want to pull it apart. It's on the ground, on wheels,

I just got through sand blasting 30 years of crud off of it. It's not holding up my progress on this project, I've had it for as year but had never roll it. Any advice appreciated.

If it came off another EB, then it will have the possibility of having Ford's old limited slip, I don't remember what it was called, trac-loc or something like it. Do you know where the original frame that it came off of is? If you do, get the VIN off the frame and you can look up what the axle code is and it will tell you what you have. But the only markings it will have is an aluminum tag on one of the case bolts that would tell you what gears it has in it. The limited slip will be identified by the VIN or by having someone hold one tire and you turn the other. If your friend gets resistance in the same direction that you are turning, then you have the Ford LS 9"

Hey S_bolt, VIN # is long gone, I found the tag WFP-8 2HE 3JL50 9 6951 --- as best I can make out.

The 3rd member/snout has a lot of casting numbers; 2G13, D2SW, 46681, 2H10, then the little circle of numbers clockwise from 11 o'clock are #'s 1, 3, 5, 7,6.

I'm trying to cyfer' the tag. I'll get me a helper this weekend and try some spinning techniques!! I had about 3-4 opinions, my fear is that some good ole boy borrowed his buddy's welder!!

 

[S_bolt19]

Just by looking at those numbers, it looks like you have a small bearing carrier with 3.50 gears & limited slip with 28 splined axles.

WFP-8 (or possibly B) - Bronco axle 70-71

2HE - I don't know

3JL50 - 3.50 Gears w/possible limited slip

9 - I don't know

6951 - I don't know

As for the numbers on the 3rd member & pinion housing, I don't know anything about those. I will keep looking to see if I find anything further on the axle codes and if I do, I will post it up for you, but I feel fairly confident in what I have given you.

 

[broncobenny]

S bolt, yes sir you correct! Everything I'm finding is right along those lines. The "8" could be a "B" . The "9" is the 9 inch. The "L" is a Positive Traction of some sort?? I have not been able to cyfer all the numbers, I've been to 8 or 10 web sites, they're not all exactly the same.

The 3rd member markings are casting dates, etc. nothing that relates to the inards.

Thanks for you help! I think I may just hook it up and see what happens. That will be 6-8 months down the road.

 

[S_bolt19]

Yeah, I did some more checking and it is a LS rear end. The one thing I would watch with it is that it being out of a 37-38 year old vehicle, if it has any miles on it, the LS might be on it's last leg. The original Ford LS weren't that great to begin with, but they are definatly better than an open carrier when it comes to wheelin'. They have a clutch pack style of engagement system in them that has been known to go out. Just keep that in mind when you do put it in. It will not take the abuse that an Auburn, Detroit, OX or ARB will, but it isn't bad either. Glad I could shed some light on it for ya.

Hey S_Bolt, Thanks again! I got to asking questions before I did my own research (dumb) and when I went back to that little tag

it looked totally different, of course I used a maginifing glass instead of just my bi-focals (getting smarter). I got too many projects going on at the same time, I'm getting gun shy when something (else) don't go just right. It woud appear that someone has been inside that rear end, it's been re-gasketed and the 3rd member had a redish color paint. I'll probably go through it just to "know".

The actual numbers are:

WFP B 2HE

3L50 9 695B

Thanks again, sometime I also need to inquire about your Cage supension

Hey Thanks, that site sure has some good info pulled together!

Broncobenny,

PLEASE, if you could follow this link...

You don't have to register to read it. It might take a while so if you don't have the time, I understand. However, if you do have the time, watch the two movies I posted. The first one almost fits your description to a tee but the second clip has thrown me for a loop...with the tires off, the axles don't spin freely like they do with the tires on. Very strange. If you resolved your issue, let me know.

There is a breakdown of the codeing for your vin tag in your glove box as well that someone posted for me which was real helpful.

Thanks and I hope you figured it out for my sake. [-o<

Hey Dude, I don't know how large that town you live in is but you got two fellows there, broncoformudv and oddball that sound pretty sharpe on 9" er's. I read through most of those posts twice and they're dead on with their info. I'd bet money some PO

"fixed" or "patched" something just to get by (which we've all done at some time).

The computers at the fast food auto parts houses are fast & easy but not always accurate, but then I ordered a radiator from a major Bronco house and it didn't fit, the one from Advance auto did, the Advance harmonic balancer had 3 holes, mine had 4 and they told me I was wrong!!! The Bronco house balancer bolted on. So go figure.

Oh yeah the Bronco houses also tell me I have the only 2 - 1974 302's with points ignitions. "ALL" 302's from 74 on have

elecrtronic ign.

Oh yeah again good looking kids!!

Go get'em!!!
