Bent LH Control arm why?
Found this today, my LH rear control arm was bent upwards.
Any ideas why?

Re: Bent LH Control arm why?
Because of a poorly designed component. The adjuster should never be in the center of the arm like that.

Re: Bent LH Control arm why?
What brand is that one? Not that it really matters what brand since a single adjustment point in the middle is a bad design whoever made it. Also the reason I bought LCAs & PHB that have adjusters at the ends.
The good news on yours is that the tubes appear, in the pic, to be fine & you might be able to get away with only having to replace the adjuster piece in between the tubes.
But I would switch designs regardless, even if you did just replace the piece for now & svaed up for new LCAs. How many passes are on those?

Re: Bent LH Control arm why?
We had an interesting discussion a month or so ago about this kind of design on a panhard rod. I argued it was a bad idea due to this kind of problem. If only I could find that thread, your picture would be great to add.

Its Spohns LCA...
The tubes are OK, so I'll will straighten the adjustment bolt until I get a new one shipped.
The swaybar is also from spohn.
OK, I will think about getting another design later but will go under the car some more this weekend and look closer for something "odd".......

Re: Bent LH Control arm why?
DO NOT straighten out that adjuster and run it like that... that's an almost guaranteed way to cause it to break... it's junk- throw it out..

Re: Bent LH Control arm why?
Shouldn't take but a few days to get a new adjuster mailed to you. State Inspection is not worth wrecking the car or somebody elses car if it failed on the road.
