So I took out both sides front wheels and I checked both sides main spring (main spring on top and helper spring on bottom). I tried to move the driver's side main spring by hand and very tight.
but the passenger's side is kind of loose maing spring. I recorded video in here :


Both are same preload.

Please help me out
Check the top hat bolts. Tighten with impact gun.

DO NOT use an impact gun on your strut shaft top nut. Well, unless you want to screw up your struts.

Check their torque properly, it's not that hard if you have the right socket (ECS sells a variety of sizes of them).

Another thing to check are your drop links to your sway bar. Had one side loose once and they make everything from a very soft clunk to a loud bang depending on how loose the nut is.

Its fine as long as you don't do something stupid like spin the shaft or severely over torque.


I've used this method countless time without issue. As with anything use common sense.

An impact wrench hammers the nut and the shaft in the right direction to tighten the nut at the top. However, it's also shocking the shaft in the right direction to loosen the other nut at the bottom inside the shock that holds the valve assembly in place. That's why the shock manufacturers say you shouldn't use an impact wrench for the top nut.

I think what we are saying is that it's doubtful that the spring itself is making noise. When the car is on a lift the springs will be loose, not sure what to make of the side to side differences (do you have the same ride height, has the car been properly corner balanced?), but once you have weight on the suspension the spring is not generally going to be making repeated noises. However, one exception would be if you don't have a thrust sheet or torrington bearing under the springs, then the spring will click or pop as the spring compresses as when it compresses it also wants to rotate. This noise will then be mostly heard over bumps.

My bet is you have something else that's loose. Good luck.

Obviously they are not the same "pre-load" as there is no load on the spring in the video and some pre-load on the other spring which won't move.

I think you may have just solved a noise issue I'm having, thank you!

If you wrap them in foam, they won't bang around so much
