After freeing up ball joints, i was still left with a bent arm,so cut up a old screw driver which fitted into the slot on the arm-

Now checked the rear, also all seized up, it easyer to remove with brakets-

The constant movement subjected to this ball joint,its hard to believe they become seized.Its not the first time this has been mentioned on the forums though, and the bent arms have been fabricated in the past by members.

Well worth checking them on a regular basis and applying a bit of lubrication.

Well spotted.

Well my ZT was not used for about 8 weeks before i got her, that may be why! But ive done 10k from then to now, so you would think they would free themselfs!

Another top Quality BMW made part:D

Apparantly putting them in the freezer straightens them back out;)

I wondered why I had to keep adjusting mine vertically, will check sensors tomorrow as its dark and hissing down, great how to pics. Cheers

But filthy nails though:D

Good thread man.

Im gonna silicone spray and grease mine up tomorrow.

Sorry i will clean them before next pics!

checked mine today,plenty of daylight and warm and dry, back ok just needed greasing, front sensor brackets bent 90 degrees and arm rubbing slightly on drive shaft, bent them back,didn't break luckily, greased joints all working perfectly now.

Ps. wore gloves but still got dirty nails when they split!!
