Rebuilding 4X4 labs swing out - rusted on. (1 Viewer)

[unclegit]

Trying to rebuild the swing out on my truck - the cap and castle nut came off easily enough , however it's all rusted to heck and the top bearing inner race appears to have rusted to the spindle.

Some things I've tried -

Percussive persuasion - no dice - but the screwdriver did slip and chew up the top of the bearing cage.

Tried getting a 2.5 ton gear puller under the lip, but the jaws won't get under the lip with the sleeve so tall and close.

I tried putting a hi-lift under the arm right at the closest point to the pivot point - but I just ended up with the ass of the truck in the air.

Tried heat, but it was just a butane kitchen torch and didn't get hot enough.

Anyone got any other ideas ?

I think the next step is just use pliers to pull the bearing case apart, head to the store for a 3lb brass sledge and cold chisel and punches, and just hammer the rollers down and then take a cold chisel and try to split the inner bearing race - just a little concerned about destroying the spindle.

I've dealt with this. You need more heat. Lot's of heat.
Go get a MAPP torch at the hardware store and get after it.
I did as you did. High lift jack on the arm as well as cold chisels wedged around the base. Heat and penetrant, then a 3 lb sledge to the top of the spindle. Make sure the nut is on to protect the threads.
Do you already have the rebuild kit from Luke?

Yea rebuild kit from Luke is sitting on the toolbox - good call on putting the nut on to protect the threads.

Did the chisels etc work or was heat the key ?

I wedged the chisels opposite of the pressure from the high lift just so the upward force would be even and straight up and not twist the spindle. I hammered the chisels under the spindle as I cranked on the high lift.
I wouldn't try to cut the bearings or races. I'd just be persistent with the heat, PB Blaster and pressure.

Try an air hammer. I did mine a couple years back. Wasn’t as bad as yours. I put the cap on with silicone to seal out water.

Victory is mine.

If anyone else runs across this thread with the same issue - here is what worked for me.

Constant pressure from the hi-lift didn't do much in my case - what did work was I put a block of wood under the swing arm as close to the spindle as possible and applied violence with a 3lb persuading stick from below after having heated the top bearing with the MAPP torch.

Felt like it really needed the shock load to break it free.
