Alright, what am I doing wrong here? I've recently given my suspension a full overhaul. Stock setup: Shocks, struts, ball joints, end links, tie rod ends, compression rods, all new. I'm only lowered on Z springs. Used KYB shocks & struts with Moog mounts.

My right front strut is giving me a headache. A week after install it developed a metallic rattle/squeak sound. Ordered a warranty replacement for the strut mount, now the new mount is starting to make the same noise. Is it possible to get two bad strut mounts in a row, or am I installing something wrong?

Double checked everything. If I remove the nut for the strut and spray lithium grease it quiets down some. I'm really just confused how that can squeak so much, there's no moving parts.

 

I just replaced my 05 g35x with coupe springs, kyb mounts, and kyb struts and I get a squeaking noise from both struts now. From what I read it's the strut mount, and I was thinking of going with Monroe mounts. Let me know what you come up with.

 

So, I figured out the noise was actually coming from the left side. The warranty replacement did have a minor difference in the hardware used to bolt the mount to the chassis. Essentially both of the original new mounts were faulty. I was pretty fed up with the noise, so I replaced both Moog mounts (faulty original & replacement) with my original OEM mounts with 200k miles on them, and there is no sound!

Since I had replaced the struts so much, I figured out how to remove the mount without having to rent a spring compressor. Had the old stock ones put back on in about an hour and a half.

One thing you can try before fully replacing the mount is to tighten the nut on the strut as tight as possible. What I did was pop the strut bellow down (the dust boot) and clamp onto the shaft with some vice-grips. (Yes, this isn't recommended, due to scoring the shaft a little, but it's up so close to the mount that it will never "enter" the shock to mess up seals.) Once clamped, tighten the nut with a breaker bar. I was able to get about 1/8-1/4 turn tighter. Then you can slide the dust boot back into place and see if it helps. Don't know if I should have tried that originally, but I've been replacing shocks/struts and suspension work on my own cars for years and have never ran into this issue.

 

Good to know thanks, will tighten it up and if that don't work will try Monroe mounts because my originals were shot
