Super Newbie ? - Removing Rotor


Recommended Posts

This also is going to be a problem. Its a tight fit and almost always hard to remove. I sacrificed a bolt for this long ago. I call it s "banging bolt". Just know if you do this the bolt will be USELESS for anything else.

 

Turn the wheel to gain access. Insert bolt most of the way so as much as possible of the threads have made contact. Give the head of the bolt a good solid whack with a three pound sledge. Remove the bolt, replace it in another hole and repeat. Don't get carried away, you NEED TO Remove this as even as possible. Once you finally get it out, clean all mating surfaces REALLY GOOD. Wire wheel works well for this. When re-assembeling, apply a coat of anti-sleaze, you know the silver stuff.

 

Good luck,

CW

 

Just got done trying that with some 4" bolts that I picked up on the way home... Not even a BUDGE...

 

After I get the Kids to bed, I'm going to try one of these two methods I found on JeepForum and JeepsUnlimited...

I have had great success with removing the hub by using a sacrificial socket. I have a 12 point 13mm socket that I use to put on the bolt after it has been loosened about a 1/4 inch. I loosen all three bolts and put the socket on the bolt while there is that 1/4 inch gap between it and the spindle. Then you hit it with that new 3 pund sledge you have. move the socket from bolt to bolt around the three. don't go in a circle if you can. go back and forth. It will take a while but between the pb, the sledge and the socket I have yet to not get one off. I even have pulled a set in the JY to have spares for the trail.

I feel your pain. i too had to deal with similar problems on my build. I needed to get my hub off to replace the hub and u-joint. I also had a rim that would not come off the old rear axle. we tried everything, pb blaster, 10 lbs sludge and hanging on it. that thing just didn't come off. we had to get another rim and tire from the junk yard.

I went back out with the 4" bolts and beat on em some more (since my kids aren't going to bed anyhow) and finally got the thing to pop off...

What an F'in nightmare... makes we wonder if I am going to be able to do the ball joints, but I have it taken this far apart, so it would be silly to stop now...

Your new best friend should now be a wire brush(preferably a wire wheel on the drill) and some anti-seize with locktite in just the right spot.

 

Yes... Along with the Ball joints, I'm am replacing the Hub's and Rotors/Pads and Axle Shafts as soon as I get the Inner Seals and Block-Off plate... But for sure the Anti-Seize....

You can pop the hubs out by putting a bolt between the axle tube and ujoint and firing the truck up and turning the tires... If you have power steering that is.

 

I've done it a few times.

 

 

And for everything else I'd either have used a sledge hammer or lots of heat. I've never wrecked a rotor with my sledge yet, and I use an 8-pounder. You just need a little wood.

It is supposed to pop off by hand. They do get stuck sometimes. Get a small piece of wood and a hammer, and put the wood behind the rotor, and give it a good whack. Turn it, and go again. Keep doing that till it comes off. Do not hit the rotor directly, you'll damage it. That's what the wood's for.

 

It IS 4wd right? 2wd ones have the bearing and rotor assembly all one piece.

 

Not all 2wd Comanches have the the 1 piece bearing and rotor setup. My 1986 2wd Comanche has the rotor and hub setup where the rotor just pulls off of the hub like the 4wds. My factory shop manual says that they built them both ways, So you could have either setup with a 2wd Comanche.

Get a ball joint press from Advance Auto (if you have one close to you). The kit is quality, and aided in my ball joint replacment. I even broke it (but it still worked fine) and they didnt charge me for it.

 

Oh yeah, its $150...but you get 100% back when you return the rental tool.

That's right, my neighborhood Schuck's Pro Shop told me mine could be either setup. I've yet to pull it off to find out but that's the next project so I'll know soon enough. I could also have 1 of two different rear drum setups.... width of shoes I think they said. Strange. Like the factory had extra parts lying around to use up or something.

I don't know for sure but I think it was SAE. maybe 1 1/8 but don't quote me. I made 3 trips to the tool tore when I did mine and I would have to try my sockets to tell you for sure.

 

Well, it seems that most of the other stuff is Metric... The Top Castle is either 19 or 22 mm, and I think the drag link bolt was the other...

 

If I remember right, the 1 1/8 SAE I tried last night was too small...

ya not quite the right tool but hey

 

:D I was going to post a similar but you beat me. We call this invaluable tool an Alabama Universal Socket set. 'Course you need the 24" galvanized pipe Power Extension to make the set complete.
