Suspension Making Scary Sounds... HELP!

[VF143Falcon]

OK, 2008 GT. Rear suspension is squeaking VERY loudly when its like 35 degrees or colder, and clunking from the rear end fairly loudly when ever there is decent movement up or down in the suspension or even when i come to a complete stop or start from a stop.

I have J&M Adjustable Race (full heim joint) LCA's and J&M Adjustable UCA as well as a Steeda sway bar with the aluminum brackets. I have been having problems with it for about 6 months since I had it installed. Im about ready to strangle this shop who was so incompetant when I asked for the old parts and instructions they told me they threw them away

Help me stang net, you're my only hope.

Also my CDC Ducktail spoiler cracked from the cold. Sad sad story

Link to the parts:

I know I have read people say that the UCA brace causes a squeaking noise because the holes for the bolts are too big.

I thought they had those holes are too big filler plates adapter monos... hmm

Your problem is aftermarket suspension. If the bushings are not properly greased they will squeak.... and as for Heim joints they will crackle and pop loudly under load.
