Rear Axel Removal -last 2 bolts!!!!

99 jeep GC Laredo 4.0 4x4

I'm replacing my bad Dana 35 3.73. There are 4 control arms (or whatever).2 connect to lower frame and axel. 2 connect up to the top (2 ends to the jeep, one end to a single bolt on top of the axel, that upper one is the issue.

I can't get those 2 bolts off. They loosened fine but there is a nut or something still holding them in. They will not retighten either. They just spin, same thing on each both each side!

There is no way to access the top of these bolts that I can fine. I even pulled the carpet from the rear seat and checked.

I'm stumped! Any help would be greatly appreciated.

I will try to attach some pics.

Re: Rear Axel Removal -last 2 bolts!!!!

There is in fact only 1 upper rear control arm, the A-arm. It is held in place with two bolts on the forward side, and a single ball joint on the rear. The ball joint has a single nut, so iīm not sure why you are talking about two bolts?
The ball joint can rotate when turning the nut, so it should be hold with a wrench on the square end. But even if the nut is of, you probably will need a puller to push the ball joint out. Easier is to remove the whole plate which holds the ball joint to the differential housing. 3 Bolts hold it on there. It works easier (but still is a pain in the a$$) to jack the rear up and put it on stands (safety first).
You can then install the ball joint directly on the new differential with its three bolts and donīt have to mess with the single ball joint nut.

Re: Rear Axel Removal -last 2 bolts!!!!

Yes that's the A arm with the Ball joint and bolt in the middle. There is 1 bolt at each end od that arm.

Those are the 2 bolts I'm talking about. That's how they disconnected the new axle I I got from the junkyard.

Each end of that A arm has 1 bolt that goes up into a bracket through an end of the A arm and into the metal below the floor.

It's there the bolt is spinning. They has to be a nut on the other end. I was thinking it was welded and broke loose. But the other sidea of the A arm did the same thing.

Hopefully this picture attached ok. It's the bolt in each end - forward bolts I think you called them.

Re: Rear Axel Removal -last 2 bolts!!!!

There are indeed cage nuts on that side in the body. They must have broke loose from the cage they are in. That will not be an easy one to get to. Maybe that you can drill a hole from the cabin side to get access to those nuts, but you will have to measure very well where their position is.

Re: Rear Axel Removal -last 2 bolts!!!!

If the two bolts are still snug (no axial play), you could decide to leave them as is and remove the A-arm from the "new" axle.

Re: Rear Axel Removal -last 2 bolts!!!!

They are both pretty loose, almost off.

Are those cage nuts attached to anything? If so, I was thinking about drilling a small hole up from the bottom as close to the bolt as possible. Then putting a screw in which would hopefully go through whatever that cage bolt is attached too (or at least stop it from spinning) which should hold it long enough to get the bolt out. But if it's just a nut up there that idea will not work.

The only thing left then would be cutting through the floorboard from the inside to get to the nut. That would be a bummer!

Re: Rear Axel Removal -last 2 bolts!!!!

I never saw it, but expect the cage nut housing to be welded to the beam. Or the weld came loose, or the nut can rotate inside the cage. Eventhough you maybe could hold the nut in the way you described for removal, the question is if it will also hold it during installation. Maybe a one inch hole above the nuts in the cabin floor would be the solution.

Re: Rear Axel Removal -last 2 bolts!!!!

Thank you for the help. Here's a pic, hopefully you will never have to see one again!

I drilled a hole close to the bolt through the floor so I knew where to cut. Then cut carpet and took an air hammer and opened up abut a 2" hole. It is a small bracket I don't know what originally held it in place. But it was rusted bad, worse than underneath! Put a wench on top and bottom and used some old fence post as breaker bars!

PS the holes will cover up good will the carpet and insulation. Be careful on the drivers side because there is a wiring harness there. Just move it out of the way.

Hopefully this helps someone else some day.
