Horrible noise after Z1 upper control arm install

wideglideleon · 03-24-2016, 04:33 PM

Dropped of car at he shop at lunch today.
I'll let you know what they find out.
They are the premier suspension shop here for modified cars IMHO.
There was a new Chevy SS there getting lowered and an exhaust done when I dropped off the Z, and I see lots of lowered old hot rods there all the time.

I also let them know what John@Z1 posted about the torque spec.

UPDATE!!!!

Well this morning I tore back in to the upper control arms.. I loosened the two bolts that hold on the arms to the frame. I then used a grease gun on the two grease points.. (Note I put enough grease in the bushings to the point they were starting to pop out) then I sprayed some white lithium grease on both sides on the bushings that touch the frame. I then I used a jack with a block of wood and compressed the suspension. Then retorqued the bolts to factory specs. After about 1/2 a mile there was no more noise!!

Please check to make sure the outer joint is torqued to 37. If it persist please don't hesitate to call.

We don't know there is a problem if there is no call.

Are you talking about the ball joint?

Idk if the directions stated this but EVERYTHING suspension should be torqued with the car on the ground. What I do is lower the rotors onto wood then tighten. If you tightened in the air it could be your problem. That noise is very suspension related. Somethings not right and loose.

Glad to hear you fixed the problem. I will be purchasing these control arms soon.
