 1997-2003 – Rear upper control arm DIY, how to remove and install')){kind=link}
Put a jack or a stand under the wheel hub.
when should i replace my control arm ?
I have tried to use several vice grips (flat jaw) and I was able to break the ball joint nut loose and unthread it just a tiny bit but not It wont move out any more and the hex end is so worn that it wont grip on any vice grip! I have read in the comments with someone with the same problem and he used propane torch. do you suggest using that or any other ideas?
never mind yest alignment required missed that at the end of video.
what I struggle with is “torque with suspension loaded” and how this would be accomplished if you have to put wheel back on and have no access to do final torque.
does the vehicle require an alignment after this replacement when you included the guiding suspension link also
How about a tutorial on taking out the lower one?
@bentleypublishers
I was not, I had to carefully use a propane torch set low then it came right off. Thank you for your response and tutorial however.
Are you using flat jaw vice grips?
The ball joint/bolt spin when I use my vice grips. The nut is seized up, PB Blaster and a mallet don’t seem to work.
Im going to have to take your word for it, but Id change wording to use a spanner, and if that fails, then use grips.
The hex on the ball joint stud was worn and being New England vehicle this being common. Vise grip is best way to deal with it.
1.15, he locks it on a perfectly good bolt end machined with a hex to accept spanner.
Take note of how the locking pliers are being utilized. While in place the pliers prevent the lower swing arm from moving back in to place with wheel bearing carrier. Without this technique the wheel bearing carrier would have to be removed. Not a farmer but a seasoned BMW mechanics trick of the trade.
Thanks for viewing.
Vicegrips, on a Bmw while doing a tech by Bentley = Fail. Sorry Bentley, vicegrips are for farmers.
