94 YJ Mixed part problem

I am unbelievably frustrated with this and I do not know what to do. The axle shafts got replaced in my 94 with some 87 ones from a parts axle.

Because the axle shafts are from an 87 they have different spacing from the backing plate of the hub, and the whole bracket for the end assembly. This makes it so the rotors are jammed up against the bracket and don't let the wheels spin.

The rotor is too deep so I tried a different rotor kicking around that fit perfectly but this one is too shallow. A happy medium would be perfect.

Now I need to find a couple rotors that will fit with the jeep 5 bolt pattern or some type of spacer holds the rotor off the hub a bit.

My idea was some thick solid washers. Two on each stud behind the rotor itself to space it away from the bracket.

If anyone can help that would be amazing, winter is coming and would love to get my barely rolling 91 YJ off the road!

Washers/spacers sound like a very bad idea if I understand what you are saying.

I would rather have a broke Jeep, than no Jeep at all.

Was the old one working??? If so take it to the parts house and match it up. If not I don't think the washers is a great idea so you really need to find some new parts for that thing from the right year. I have worked on a lot of rigs and done god awful sh$# before but not the brakes.

wouldn't it be easiest/safest to just get the right axle shafts?

to use the old axle shafts I believe you need to change to the old style caliper mounts and calipers.

The only options I can see are:
1. A new passenger axle shaft. ($250 with shipping) (also none in any local wrecking yards, no parted vehicle parts kicking around at all for sale)
2. Replace the whole brake, end mounting unit with the ones off the old axle. (Huge pain in the a**)
3. Finding some rotors that will fit nice and clean. (All they have to be is slightly shallower and they will fit perfect with everything lined up.)

Oh boy. I'd say I'd go to my local yard and get you one but shipping for you would be killer.

What about deleting the vacuum disconnect and use a xj shaft? Just another idea

I'm confused. I haven't messed with a D30 in a long time, but I don't see how the length of the axle shaft is affecting the brake rotor. It rides on a unit bearing and the shaft bolts through the center of the unit bearing. The brake rotor isn't attached to any other part iirc.

*Edit* Sounds more like there is an issue with the unit bearing or the way it was installed.

Well the whole assembly on the end of the D30 axle is different apparently. 87-89 is different than the 90-95's. The whole bracket, axle shaft/unit bearing.

The XJ/ TJ shaft swap would work, but I can't find either of those also.. :/

Ah ha! I have an idea

Just for fun look at the other side and make sure all your brackets mirror each other.

Could be something is on the wrong side of the assembly

The issue is on both sides, exactly the same. When the wheels are snugged up the rotor gets pushed into position which is right into the bracket. This is because the axle shafts out of the 87's spacing in 3/4 - 1 inch off. Thats it.. :/

Dd you replace just the shafts, or the sealed bearing/hub assembly as well?

Everything. Its the distance from the backing plate of the wheel bolts and the triangle 3 bolts that attach it to the whole bracket. If i took the u joints apart and used the 94 hub/bearing shaft after the u joint that would fix the spacing issue... I'll have to try that. Now, to get those u joints apart without breaking the damn arms again... lol.
