I just recently changed my Lower control arms on my Z. The rearward arms (Crescent shaped ones). Everything works fine, However after a day of driving, I'm now getting a squeak in the front when I drive over minor bumps in the road. I jacked the car up this morning to see if maybe I didn't tighten up a screw or bold, so I went back at it again going over each one and tightening them all but the squeak is still there. I'm am lost and dumbfounded as to what it may bey. If any of you guys have had similar problems, give me your input or suggestions on what it may possibly be. Thank you!
