Ok. I know these rear ends are good and highly sought after.
I have a 9" that was either shortened or came from an erly Bronco. This rear end will fit Early bronco's, scouts, Jeep Wranglers, Bronco II's and some small cars. It has been sititng outside in my yard, off the ground, for a couple years and I think it is time to find it a new home. It has drim brakes on it and the housing looks to still be in good shape.

My question is this: What would it be worth? Povided I find the correct buyer. I am about ready to get rid of it for $100(haven't mentioned price yet) but the same guy I am gonna offer it to said he would give me $200 for a 82 F150 2x4 rear end. Should I ask for more?

 

I really don't know the value because I have never been in the market for an axle, but some things to look at are:
31 or 28 spline shafts or?
Locker, posi, LS, or Open
Big or Small Bearing
Gear ratio.

There are probably other items to look for, but I can't think of 'em and some of these you can check without opening the housing.

Also you might check the For Sale section at www.classicbroncos.com to see what they are going for there.

Thank you for the help.

I really don't want to open it up. I do know the brekes are locked up or somthing because I can't pull the drums off it.

 

Get an old lug nut and thread it on the stud about 90%, then bang the studs out most of the way. That will get the drum off. Do you know how to check the stuff I mentioned externally? I can help you if you don't know.

I have no clue how to check any of it externaly.

I am still farly new to the mechanic world. I'm a PC tech and I can fix car stuff if I know whats wrong but figuring out what is what is another story. I work on cars/trucks as a hobby and like it as a hobby. I just have some parts I came across, don't remember were everything came from, and I would like green paper to replace them.

 

place the axle on Jack stands or whatever so you can turn both sides and the pinion (u-joint).

To find out if it's open or limited slip (LS) or locker, turn one side one way by the drum. If the other side spins opposite, you have an open diff. If it spins the same way you have a LS or Locker. I 'think' with a LS you can have a partner hold one side and you spin the other, if it's hard to spin, but you can still spin it without the other side spinning, then you have an LS, if you cannot spin one side without the other, then chances are you have a locker.

If there is a small flange behind the brake backing plate, then you have a big bearing (better). If there is no flange, then you have a small bearing (pretty good). This is the best pic I found of a big bearing.


gear ratio: mark the drum and the pinion or yolk. Now roll one side one full rotation and count the times the pinion turns. If it turns three and a half times, you have 3.50 gears. If it turns a little over 4 times, you have 4.10's. This can be tricky because if the brakes on one side are dragging, it messes your count up if you have an OPEN diff, usually by cutting the yolk turns in half. Make sure both sides are spinning at equal speeds to get an acurate count. If not, I think you can hold one side, roll the other then double the amount of turns your yolk does and that's your gear ratio. I can't say that last one will work for sure, but I have had that experience. We followed these steps 10 times and we kept coming up with 2 yolk rotations for every tire rotation., but one wheel wasn't spinning so that cut in half the yolk rotations.

Thank you for the info. I actually remember hearing the gear ratio thing before with spinnig the tire and seing the yolk turn. I also know about the posi vs regular rear. The holding the other side to see if its a LS is new tho. My problem is I know some stuff but the file cabinet up there is in shambles and unless someone mentiones it I never think of it. I also didn't know about the big vs little bearing thing. All I knoe is that the 9" rear end is fairly bullet proof.

I will try and get all in info on it to aid me in selling. That is if the brakes aren't locked up.

I knew there was a reason I liked this forum over some others. Everyone here is helpful and friendly.

If I can help you with somthing just let me know...

 

That's what it's all about IMO! You help the next guy out, and he helps someone and so on. Just glad I can help.
