Hey guys I recently installed some black works racing LCA's and subframe brace. The next day I drove the car like usual but while on the freeway I came across a bump and heard a rubbing/creaking noise coming from the left passenger side. So I went back and double checked everything also retorqued them to spec but it's still there. Keep in mind that the OEM LCA's never had that problem. I'm not sure what else to check and need some guidance please!

 

Its probably because you have polyurethane bushings in the new control arms, and factory units have rubber.

 

Is there anyway to resolve this issue?

 

Have you had the car aligned yet? If not, I'd remove the lower control arm and liberally apply anti-seize to the metal sleeve, bushings, and hardware to try and prevent binding. Sadly, Polyurethane will always be noisier than rubber. That's the nature of the harder compound it is.
