Coilovers squeak over bumps constantly
I'll preface this with saying I've read through numerous threads related to this but couldn't find an answer.
Last year I installed a set of base FA 500 coilovers on my car, everything was perfect and the car made no noises, after some time I began to hear a squeaking sound from the drivers front whenever I would go over bumps and the suspension would travel. I sent an e-mail to FA and they sent me out some grease to place behind the dust boot, on the shaft that enters the shock body. That resolved the issue, but after driving for around 100km the squeaking came back. I've tried the FA grease, regular WD40, and the white lithium WD40 all of which work but only temporarily. I'd rather not send the coilover back since I drive the car daily. My current theory is before I had put on coilover covers I drove through some water, it went into the shock body and corroded some piece and that is whats causing the noise. Has anyone heard of something similar, or has any recommendations on what to try before I begin disassembling the coil?

Been through this I live in Montreal and running tarmac zeros on my 2010 legacy gt, I have the same issue and changed a whole bunch of parts on my suspension had them rebuilt and tried lubing near the top hats but it persist, and read somewhere it is just part of the coil over life and using the car all year round with the salt during the winter doesn't help. welcome to the club, at this point I just tolerate it. I only hear it over speed bumps otherwise it is quiet.
However if you do find a solution please share!! |

Find some marine grease. Plenty of brands out there. Pick your favorite or let your budget dictate the choice; either way, I believe marine grease is your better option. If there is nothing holding the grease in place, such as a boot/seal, and it is in a place that moves (up and own) a lot, you may need to add grease periodically and make a schedule (like the 1st of every month) and reapply said grease in the affected area. Racecar parts need racecar mechanic attention. |

Apart from the FA grease that they sent me, the rest have been pretty thin so maybe that's it? We'll find out I guess. |

Sorry for the double post, but I fixed my issue in the dumbest way possible. I was driving home from work, and I accidentally sent it on a road I wasn't that familiar with. Hit some train tracks coming out of a turn and absolutely belted the corner that was squeaking. It stopped 90% of the squeaking, I looked them over after I got home and they seem fine. They do still make some noise but it's few and far between now, and it's what I would deem an acceptable level.
10/10 would not recommend doing that if you're having this issue. /shrug |

Ok... I lied, like a liar would. Everything was not okay when I inspected it in the day time.

Liar!
So, looks like when you smacked it coming out of the turn you * broke loose " the suspension which was causing your problem. Maybe that corner was all jammed up or already failing. Time to go back and re-check everything else in your suspension to see what other damage there may be in there / you may have caused. At a minimum, you are going to need new camber plates. Hopefully you didn't bend the coil-over shaft or you are going to need to replace a set of coil-overs. |

Wow. You think they were broke like that before you took the hard turn or they broke at that time?
You should try out a set of Vorshlag camber plates, you hear a little road noise but they work very well. Also I have raised AST camber plates on my 5100's, they are really quiet but not sure if they can work with other coilovers. And another plate that I always seen a lot of good about is the ground control plates. Good luck, I hope you get it all sorted out. |

I think that corner was already failing, and that's what was making the noise, this was just the final nail in the coffin. I just got in contact with FA support, and they're sending over some new pillow ball mounts next week. Seems like just bad luck to me, FA support has been great though super helpful and responsive. Time to buy an impact so take swap parts and I'll be back on the road in a couple ugga duggas! |
