When I turn the wheel, the spring on the coilover moves and makes a popping noise, I have tightened the perches pretty good, that kind of helps, but a day or two later it is back to making the noise. Any idea ? Maybe there is something I didn't tighten down?

 

Usually due to spring binding (torrington bearings can be used if that is the case), but more info is needed.

1) What type of coilovers?
2) How low?
3) Does it happen more when moving slowly?

With some setups, the front sway will contact the tie rod. This happens more when rolling and turning to full lock. It will make a loud pop when it slides back off the tie rod as you straighten the wheel out. Could be that as well.

 

They are Megan Racing Coilovers, There is about a half inch wheel gap in the front and it happens more when moving slowly due to turning onto streets or perhaps a driveway. When you look into the wheel well and look at the coilover, you can see the spring turn when the wheel is turned.

 

When I did my megans I also did front sway bar, To get it in i unbolted the sub frame and while i was putting it back together I missed the lower control arm bolt was loose. so check that out solved my problem.

 

Hmm, will check it out, thanks!

 

my racelands do it too. im still not sure what it is. i was thinking a ball joint though.

 

Check your clearance between your front sway and with the steering at full lock. Just takes a minute or two.

 

Check the strut bearings.
