HUB Bearing bolts - any suggestions are much welcome

I mentioned problem in another post but really need advice!

I could not unscrew my 2 bolts at hub bearing. I damaged rusty heads and with help of one guy I cut the heads:-( I thought will remove hub bearing together with bolts but it seems I was wrong. Hub bearing is still not loose and I wonder if can do it .

What should I do now? except welding something to it?

I think you are talking about the three 12pt 13mm bolts on the inside of the knuckle right? You tried cutting off the head and it wouldn't come out?



Well even when those bolts are removed, that hub can be rusted on there pretty good. If the hub is what you are trying to replace, just show it who is boss with a mallet, or sledge hammer. Order some new bolts from the dealer or grab some off of a junk yard vehicle. Any Jeep will have them. XJ / YJ / TJ / ZJ ... not sure on the WJ or SJ's.

BFH. They're somewhat seized in, I bet, and with the bolts still in the knuckle, now it will need to come out a little more straight than it would with no bolts. Big hammer should do it, maybe use some penetrating oil, too.

*****You mentioned 2 bolts.There should be 3!!!

Penetrating oil around where the hub seats in.

If you've already cut the heads off, this might be a little tricky. If you can back the bolts out a couple of turns, then take a BFH to them (with a socket over them for protection).

Also, what I did.... Not the best choice, but it works.....

Back out the bolts (or whatever bolts you have remaining) a couple of turns. Start with the idea from above, then put the tires back on.

First just try working the steering wheel all the way back and forth. That may do the trick. If not, take it up a notch.

Bolts still loose, drive a few feet and jam on the brakes while cutting the whhel hard to one side. That should pop that hub loose.

Since you cut 2 bolts, you might as well cut the 3rd because they just pass through the knuckle. Then wack the hell out of it with a BFH straight out.

I've always had great luck with a sharp chiesel. Get the chiesel behind the hub and start tapping at various areas. After I move it away slightly, I have a small wedge I insert behind the housing, and tap that in farther, to bring it out the rest of the way.

Just don't jam or bend those bolts too much or they may never come out!

go to town on that hub with a mini sledge. i just did like 4 of them and believe me new england rust is no joke. i was hitting that thing quicker than a jackhammer. took like 15 mins to budge em. the broken bolts are no prob due to no threads in the knuckle. drop the tierod . good luck

To piggy back the air chisle comment (good idea) you could also get a blunt tip and use the air-hammer to punch the bolts out from the back (since you cut the heads off).

Just a offer but if you get the old one off and are interested I'll give you a hub along with the bolts (you pay shipping). The bearings are good and it is from a jeep I parted. PM me if interested and good luck

Pop off your rotor and cut the tabs off the hub bearing right down the center of the bolt. Cut about 90% of the way and use a chisel and a hammer to finish the cut so you don't cut into the knuckle. Then beat the hub off. Now all three bolts are exposed and then you can try using vise grips to turn them. If that doesn't work then weld a nut to what is left of the bolt and turn it out.

Thanks a lot!!!!!!!!!!!!!

Sorry I did not respond!

I was looking one week for special tools and I bought a few but bolt threads are so rusty I can't move them . I am trying with a lot of WD 40 , pepsi cola etc. I bought better pliers (heavy ones) but does not help still. I was was trying to hold end of bolt (close to thread) by pliers and screw it out. But nothing happens.

I just read all the posts and it seems it is possible to use hammer and remove whole hub bearing together with two bolts in (pins already since heads are cut off).

I was so lucky and I removed one bolt (it was hard but done) that is why I am talking about two bolts.

I have not much time to do it so it takes already one week (half half hour per two days :-) ) to remove HUB bearing. My goal is to replace half axle.

I will try heating the hub. Question was if it is possible due to bolt pin diameter move in other direction together with hub bearing

many thanks for help, appreciate this
