adj. UCA and pinion angle issues
I have an adj. UCA from GMS, I got this in conjunction with adj. GMS LCAs, I will never lower the carbut I want a one piece driveshaft at some point so i heard adj is the way to go, first issue Iwas havingwas thepinion angle was way off, like -9 degrees (-2 is good I think), took it to the shop and they adj the UCA (it was loose) as far as it would go to getpinion anglearound -4/-5 degrees, enough to stop the shock from rubbing on the body, now though when I come to a stop sometimes I here a click coming from rear/center of vehicle, just one click per stop not always, I think the UCA is getting loose again, how does this happen ? Why does it have to be adjusted all the way to get pinion angle close ?
I have no idea about supsension stuff and can't find a good suspension shop in PHX, looking to get 1 piece installed and everything set-up correctly out back, any thoughts ?
thanks

Here is a link to an explanation of LCAs and UCA and setting them up http://www.cherod.com/mustang/HowTo/LCA%20_adj.htm

They maxed out the UCA?? That doesnt sound right.
It should be a strong mix between the LCA and the UCA...
First thing is to measure the wheelbase...make sure the wheel base is correct on both sides, this will greatly help in setting the LCA...then after the LCA are set, you can adjust the UCA.
When I did mine, the finetuning from the UCA was very minimal, and the UCA is adjusted about halfway from shortest to longest. If you think its coming loose, then tighten the jamnuts so that it wont loosen up!
Its not rocketscience. Any mechanic who is half-decent with numbers and logic should be able to figure it out.
Its a very stubbon thing to do, but once you get it, tighten it down so it wont loosen.

Did you get this straightened out?
One thing that might be causing your 'click' might be the UCA mounting bolt floating around inside the mounting bracket. Steeda, J&M etc. now include an 'anti-clunk' set of aluminum bushings with their UCAs that tighten up this clearance. You can also buy them separately. Dunno if this is your problem but it might be worth looking into.
When I put on my 1 piece DS I didn't have to adjust anything. The stock UCA/LCAs worked just fine.
Now when I put on the Vogtlands that was a little different story
