How can you tell UCA's are bad?

I just put a small lift on using the Bilstein 5100's set as high as they go on stock coils. Ran fine for 3 months and now I just started getting this noise coming from the front drivers side tire somewhere. Can't really pinpoint it. It's like a really rough squeak or grind. hard to explain. Would my first place to look be the UCA's? I jumped around on the front bull bar and I don't hear anything when the trucks shocks compresses so I think I can count the shocks out here.

Any ideas?

 

just recently replaced all my struts and shocks with 5100's. My front struts I set to 1.75" to level out the front end, I'm riding stock coils as well too. Ever since I replaced mine I get a weird squeak coming from the front driver side only when turning right. Sounds like a 30 year old truck and is killing me. Not really sure how to tell if the UCA is out but from what I have heard, there is almost always a "squeak" when placing aftermarket suspension on. Some say to check the hood spacers, sounds weird but when driving if not sealed properly it will cause a squeak that will seem as if its coming from the suspension. Others say to clean the upper and lower BJ's and spray dry lube only on the grease them up. You might want to try cleaning and lubing your rear leaf springs as well, might help as well. Also heard if the BJ's are wet or covered in dirt, salt or road grime it can cause a squeak as well. might want to give it a good rinse with a hose and then try to see if that helps as well as the lube.

Drives me nuts when there is a squeak coming from my truck. Hope this helps you out Bro
