bent axle shaft flange

I've run into an issue following the axle shaft replacement write-up. My son and I cannot get the rotors off on either side; they appear to be rusted in place. I tried using my 5lb sledge all around the rotor without touching the braking surface. I sprayed a ton of PB blaster in the log bolt holes and the center hub.

I got the four rear nuts off to remove the axle shaft, but it won't come out and since I cannot remove the rotor, I'm unable to pry it out either.

I was going to replace brake pads only while replacing the axle shafts, but it looks like I might need to beat the actual braking surface from behind to get these off. Any other suggestions?

I've heard about tapping two 3/8" holes into the rotor and inserting a 3/8" bolt to get the rotor to pop off. Is that something that might work in my situation?

I have no problem replacing the rotors if I need to, but I need to get these axle shafts off! :doh:

Thanks!

Try laying a block of wood on the rotor surface and giving that a few gingerly smacks.

Bent axle flange repair options

Look at how to rotor mates up with the lugs. I had one that was centered a bit better than the others. Rotate the hub so that lug is on top. I PBed it pretty good there. Waited 10 minutes. Give it a few whacks, rotate a bit, repeat. The drill trick will work too. No sense in putting old rotors on new axles. Besides, they're bent now if you went to town on them.
 
When I did mine I loosened up the ebrake too. Sometimes u get a rust lip just inside the ebrake that wants to catch too trying to take it off.

If you try to pry on it can u see the lugs moving inside rotor or no? Does the rotor feel likes it's moving but springing back? If so it's the ebrake catching.
 
Thanks for all the tips. I decided to buy new rotors and after letting the PB blaster sit all night, I was able to bang on the inside rotor surface while rotating the axle and both rotors came off. I found the next bundle of rust; is it normal for the e-brake and other stuff to look this bad? Before I install the new axle shaft and rotor, should I clean this up or look into an e-brake replacement too? EDIT: or more correctly, a parking brake shoe replacement?

Glad you got them loose. I would just clean it up real good if it were mine. Make sure and get all rust off the friction surface of the shoes, brakeclean works great. Unless something is sticking during operation or friction part is coming off of the metal backing, I wouldn't recommend replacing it. Ebrake is used seldomly.

Doesn't hurt to change them, and you've already dismantled so you don't have to go through that again...
 
We got everything patched back up last night after trying to find a M12-1.50 nut for the bearing retention plate. Replaced the rear brakes at the same time.

Thanks for all the advice. I appreciate it!

More than likely that's a dealer part

My dealer had to special order them, so I just got on fastenal and they had them. I needed the M12-1.50 bolt for when i install my LOD sliders, but I have a manual so no bolt where the A/T skid plate attaches. Long story short, that size /pitch is a SOB to find.

I found it at the local Ace Hardware last night and got it about 5 minutes before they closed! :thumb:

I had come to the conclusion I would have to call Jeep this morning if I couldn't find one. We had to cut one of the nuts off since the bearing retainer bolt would just sit and spin while we tried to remove all four nuts while removing the axle shaft. None of the local auto parts stores had M12-1.5 nuts and Lowes Hardware only carries standard size grade 8 nuts and bolts. Ace Hardware / Town & Country to the rescue!

I too have had GREAT luck at Ace hardware with metric bolts as well as Grade 8 stuff. Way more selection than Home Depot or Lowes.
 
Bent Axle Flange? What's your thoughts?

My wife was hearing this grinding/rubbing noise. I road in the back and listened it is a SWuT, SWuT, SWuT, sound. It is coming from driver rear.

Put it up on jack stands and pulled the driver rear wheel. Put lug nuts on with spacers to hold rotor tight.

Had wife put it in drive and I could see a slight wobble.

Pulled the brake caliper off and still noticed wobble.

Pulled off rotor and flange has a very slight wobble. Doesn't seem to be much. How much if any will a shaft wobble?

After some inspection, I think the rubbing is coming from E brake. As it was spinning I had my wife engage the parking brake one click at a time. The noise got louder and longer duration of each click.

I haven't adjusted the E brake since I installed the PR60 and frankly, it doesn't work well, it is currently too loose. Tightening it would make the sound worse.

I'd like to post a video of what it is doing. Any ideas how I do that?

If you can see your flange wobble without using a dial indicator, it's definitely bent. Depending on how hard you play, it happens on any semi-float shaft. Not exactly the end of the world but it can be annoying. That being said, you'd typically hear a squeaking from the brakes pads and not necessarily from the shoes.

Thanks for the reply. I can definitely see the the flange move. And it makes the noise without the caliper on, so I'm guessing it is the shoes. I don't see any unusual 'wear' marks.
 
Most manufacturers allow .002 of allowable run-out. That's a little more than a few human hairs. As Eddie said, if you can see it, it's bent. Changing pads or shoes won't get rid of the noise. The noise is occurring because the shaft isn't straight and every revolution, the rotor is hitting something that it shouldn't be hitting.

With what I'm seeing in the video and from what you guys are saying, I guess i need to order a new Axle Shaft. Damn it, Just got this PR60. :mad: Im hoping the person i got it from didn't realize it was bent. :banghead: Oh well, look on the bright side, ill have a trail spare.
