View Full Version : E30 ball joint nut

Anyone know how to get a stripped ball joint nut off - threads are stripped?

I believe it's a nylock.

I was in the process of wanting to remove my strut when I realized it was just spinning.

You could try using a pipe wrench on it if there's enough room to get in there...

come on!! LOL be serious...the threads are stripped. not the nut.

are you sure its the nut spining on the threads and not the whole balljoint?

yes, thank you for checking. I looked at that to make sure. :-)

cut off tool or a sawzall.

I take it you've tried jacking it up on the balljoint and turning it out?

That and some heat might get it out even with slightly damaged threads, but you'll need to get an impact on there after hitting it with some heat.

yaknow, that is what I suspected. I'm just lazy.. I use hand tools because it's convenient. Looks like I got to break out my air tools and compressor. I thought about heat and impact gun..well tomorrow is another day. Thanks for the imput. :-)

Yeah use hand tools... and put a second jack under the balljoint itself...

Yup, tried that already. I suspect their has to be down force on the control arm to tighten up the nut so that I can put some tension on the thread. I have a moster pry bar but difficult do use when one hand is holding it down and the other is on the ratchet... :-)

i just lowered my e30...and i had the exact issue with the ball joint(s) bolt spinning with the nut...here is how i solved it.

pull down the rubber boot, and tighten a vice grip (http://www.motor-factors.com/osc/eshop/images/00028.jpg) on to it, of course as tight as you can!!!

should hold tight to get the nut off, but wd40 that shit good, and try to avoid getting the wd onto the boot itself.

before u put the nut back on for good, put it on, tighten a little, and unscrew, tighten, unscrew, repeat all teh way through. it just works the nut on the bolt making it easier to put on.

EDIT: i misinterpreted what was initially stated...fail el gato, fail.

Just put a jack under the ball joint and put the weight of the car on it. The ball joint's tapered and will hold tight. You can then spin off the nut with a regular ratchet / wrench.

Sorry, perhaps my explanation wasn't clear. The ball joint isn't spinning...The nut is spinning. Inner threads appear to be stripped on the nut side. I am thinking on using a prey bar to increase the tension on the nut and hopefully with a quick zap with the gun it will spin off.

any suggestions aside from this?

Get your air compressor out and cut the nut in half. Who knows, if the nut is stripped or the ball joint at this point. I had a problem with the ball joint actually stripping, nut the nut upon reassembly of my suspension last weekend. Run a tap and die over everything before reassembly.

Best thing to do is probably just to cut the nut with a cut off wheel.

yup..looks like me is going to have to do that!!!! :-)
