SuperWade2 Posted January 23, 2008 Share Posted January 23, 2008 OK... so I'm admittedly very new at most things mechanical, but I'm trying to learn as I go... I started the process of doing my Ball Joints this evening, and got stuck pretty early on... I have the Brake Caliper Off and now just trying to remove the Rotor so I can move forward to the Hub and bearing, etc... It seems that I should still be in the "easy" part of this disassembly/install, and I'm already stuck. BTW, I do have a service manual, and it just says "Remove Rotor from Hub" as if this thing is supposed to pop right off in my hand. No laughing please.

Geonovast Posted January 23, 2008 Share Posted January 23, 2008 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.

Yup 4WD... and I beat the crap out of it with a deadblow rubber hammer and it didn't budge... Link to comment Share on other sites More sharing options...

Geonovast Posted January 23, 2008 Share Posted January 23, 2008 A huge @$$ gear puller might do it. Link to comment Share on other sites More sharing options...
tjbliley Posted January 23, 2008 Share Posted January 23, 2008 Work smarter not harder. Spray right inside the hub area with penetrating oil or PB or something else. Then hit it with a deadblow hammer in a star like you would the lug nuts. In time it will loosen and come off. Give the chemical time before you start hitting it.

SuperWade2 Posted January 23, 2008 Author Share Posted January 23, 2008 OK, I soaked the whole thing in PB Overnight and BEAT the CRAP out of it AGAIN and thing is NOT NOT NOT budging even a speck..it is TOTALLY fused to the hub apparantly. Any other advice other than get a bigger hammer and keep PB Blasting it? Wade Link to comment Share on other sites More sharing options...
mjeff87 Posted January 23, 2008 Share Posted January 23, 2008 I'll throw this out there just in case.....check each of the studs to see if there is a small washer-looking thingy on one of them. They're called Tinnerman clips, most often used on assembly lines to keep things in place until final assembly. That one little washer can ruin your day if it's there and you don't notice it. Probably not your problem, but something to check anyway.... Jeff edit: only pic of one I could find- Image Not Found Link to comment Share on other sites More sharing options...
HOrnbrod Posted January 23, 2008 Share Posted January 23, 2008 Tinnerman clips huh? I'm impressed. Never knew the correct name for the little PITAs. I always called them push nuts. :nuts: Link to comment Share on other sites More sharing options...

Jeff edit: only pic of one I could find- Image Not Found I assume I would be looking @ the front side of the studs where they go through the holes in the Rotor... if so, there is nothing like that on there. I'm going @ lunch and buying a bigger hammer...Worst case scenario is that I F' up my Rotor, and Hub/Bearing... at least it will come off one way or another. :mad: Link to comment Share on other sites More sharing options...
86FUBAR Posted January 23, 2008 Share Posted January 23, 2008 Just leave the rotor atached to the hub and unbolt the hub from the knuckle and take axle , hub and rotor all out together Link to comment Share on other sites More sharing options...
SuperWade2 Posted January 23, 2008 Author Share Posted January 23, 2008 Just leave the rotor atached to the hub and unbolt the hub from the knuckle and take axle , hub and rotor all out together Was getting ready to try that next... Just the 3 bolts for the Hub, right OK, here is maybe a dumb question... does the Big 36 MM Nut need to come off before the Rotor comes off, or just the Hub? Maybe that's my problem...

mjeff87 Posted January 23, 2008 Share Posted January 23, 2008 No, it doesn't need to come off to get the rotor off. It does, though, if you want to pull the hub without removing the axleshaft. In your case, both (hub and axlesahft)need to come off to replace the BJ's. Link to comment Share on other sites More sharing options...

Maybe that's my problem... no the nut just holds the axle shaft to the hub and sets the proper tension on the unibearing , and yes its just the 3 bolts .

SuperWade2 Posted January 23, 2008 Author Share Posted January 23, 2008 Might as well continue the line of dumb questions. How do I get the Nut off since the Axle (this is the passenger side) is spinning when I try to remove it it and I already have the brake calipers off. New 3 lb Dead Blow Sledge and more crap beating and it hasn't moved a bit. Now I'm getting pissed... this sucks... now I know why I've always paid to have this stuff done... this isn't even "fun"...

mjeff87 Posted January 23, 2008 Share Posted January 23, 2008 Something's not right here.....they can be difficult, but not THAT difficult. Can you post a pic of it? To get the hub nut off, put the wheel back on and lower it back down. Chock it and hit it with an impact wrench (or a breaker bar, but it will roll more that way). But you don't need to take it off to do what you are trying to do. Like FUBAR said, pull the hub and axleshaft (and rotor) out together. If yer having this much fun trying to get a rusted/stuck rotor off, I can imagine how stubborn the hubs are gonna be :cry: Link to comment Share on other sites More sharing options...

I'm thinking at this point about tossing the Rotors and replacing with new anyhow and but if the rotors are "fused" to the hubs, then maybe I need to do something while I have it torn apart. I'm still wanting to do the Shafts from my TJ, but not sure if I'm going to do that now or not. SW2 Link to comment Share on other sites More sharing options...

Oizarod115 Posted January 23, 2008 Share Posted January 23, 2008 damn... sounds like one stuck @$$ rotor, good luck with the rest of the bolts/getting the hub off if the ROTOR is that stuck :eek: Link to comment Share on other sites More sharing options...

Dayem, a CA MJ shouldn't be that rusted, unless you wheel it underwater in the Pacific. Somethin ain't right. :roll: Well, The rotor on the Pass Side is now Off... I just went crazy and smacked the crap out of it some more. I actually removed the 36MM nut, hoping that I could pull the hub bearing/rotor off as suggested, but after removing the Nut, I still had NADA movement anywhere, so I kind of flipped out and just started bashing the Rotor all over as hard as I could (I think I blacked out a little bit)... anyhow, it FINALLY started to move and I was able to finally break it free... But now the Hub Bearing won't budge (All 3 Long Bolts have been removed)...at ALL... Any Help? As far as the Rust, I think this truck sat for a good while. According to CarFax (assuming it's accurate), the Truck had 150K+ in 1993 and I'm @ 205K now, so I think at some point between 1993 and 2007 it sat for a while, or only had 4000miles a year. Once/If I get the Hub/Bearing out, whats invovled in removing the shaft. I assume I have to open the Vacuum Disconnect box on the Tube and disconnect something, right?

mjeff87 Posted January 23, 2008 Share Posted January 23, 2008 Any chance that I can re-use the Hubs from my 99 TJ? You can use those hubs, but yer gonna have to get the matching rotors for the 99 to run on them. Axleshafts will swap in as well, but you'll need to add an inner seal @ the carrier for the passenger side shaft (one-piece shaft vs. your current disconnect 2 pc one). I haven't met a Jeep problem yet that couldn't be solved with enough beer, so post up a pic and let us drink.....I mean think.....on it a bit :D Jeff Link to comment Share on other sites More sharing options...
comancheman Posted January 23, 2008 Share Posted January 23, 2008 i feel your pain with the rotor. i went through the same thing on an expedition i even tried heating it with a torch. it took me 3 days to get it off. i just kept spraying it and eventually went into a fit of hysteria with a monster sledge. went absolutely crazy then had to sit down cuz my vision went fuzzy when i was done but the rotor was loose!!! defenitely took the fun out of the project Link to comment Share on other sites More sharing options...
CWLONGSHOT Posted January 24, 2008 Share Posted January 24, 2008 But now the Hub Bearing won't budge (All 3 Long Bolts have been removed)...at ALL... Any Help? SW2 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 Link to comment Share on other sites More sharing options...
