Default HELP - rear camber arm (lower control arm) outer bolt frozen

I am at a loss of what to do. I have beat the shit out of the bolt (the eccentric washer bolt for camber adjustment) and it will NOT come out. Somehow I managed to get one side out but the other side just is not moving. When I turn it with the impact gun it will spin but it spins the bearing as well, bolt is frozen inside metal shaft in the bearing. The nut is off but bolt does not back out.

So far this is what I've tried
Lots of WD-40
Hit the shit out of the bolt with hammer
More WD-40
Hit the shit out of the bolt with larger mallet

Put socket&extension on nut on rear of bolt and hit the shit out of that above

The bolt and threads are shot from me beating the hell out of it but I don't care I just need it out. Have a new bolt and adjustable rear camber arm I am installing.

The differential is out already and the inner PITA subframe bolts are out but this one last one is NOT MOVING.
What else can I do/try tomorrow. I can't pull the bushing with the bolt in there (can I?), would prefer not to do so.


THIS BOLT


I am installing these

Cut where and how and then, how do you get it out? It's frozen in the shaft (I think) so then how do I get it out?

Don't own a sawzall yet (can buy one) but really just want to have this out easily so I can be done and move on.

50/50 mix of Acetone and ATF fluid, should tap right out. Works a lot better than wd40.

You have new hardware, why not just angle grinder/sawzall?

If you don't care about saving the old lower control arm you can bend it/cut it/break the welds, etc. Those eccentric bolts/nuts are tough sometimes when they get stuck.

When I went to remove those bolts, it absolutely destroyed the ball joint for each side. I had to make a tool (did this job two weeks ago so I still have it) to press out the old joint and to press in the new ones. PM me if you wind up having to go the same route for details.

Wd40 isn't that good for this. Try pb or liquid wrench.

Default Re: HELP - rear camber arm (lower control arm) outer bolt frozen

Just did this on a 98 e36.

heres how:
Soaked in PB / acetone /atf for about 30 min. The PB is good because you can get a spray to force it in there. The eccentric bolts have a groove in them and allows the fluid to get down the sleeve. Then I got my breaker bar and applied force...just enough to budge the bolt. I went left then, right, then left then right...you get the idea. Adding PB along the way. If you don't want to snap the bolt, don't go too much at once. It will eventually free up. Spraying PB along the way flushes the broken down shit out...don't be shy with it.

Also when going "right' (Tight) don't go farther than it originally was, the point is for the movement to break the bond and force the junk out.

I've taken a number of these out, worst one I destroyed completely by chiselling out the centre, to leave behind just the outer sleeve which I then used a puller tool on. I'd discovered earlier that the insides of the bush are only held in situ by the peened over edge of the outer shell which is destroyable with a big screwdriver plus hammer. No pics tho. Hope that helps someone...

Ps, they become seized after two or three winters in my experience.

PB is useful if you give it proper time to work. I have sometimes left it overnight to get the desired penetration.
Do you have a set of punches? If so, have you matched the largest diameter punch to the end of the bolt and tried a dead blow with a properly weighted mallet (likely stainless steel face) exactly along the bolt shaft? Since force across the rotating axis of the bearing won't work, use the fact that the bearing doesn't rotate the other way to give you counter pressure. You may well destroy the bearing, but you may well do that anyway. If you are lucky you may get the bolt to budge.

If you have to clean up the mess of a torn up bearing be sure to do it properly and going forward put the car up now and then and check the various fasteners as part of your regular maintenance. The adjustable rear arms are no joy when seized, believe me.
