hey guys, I am trying to find source of this creaking sound from my coilovers.
I got 2012 G37 sedan. suspension setup is tein basis coilovers (about 25-30k miles old now) with spc uca, rear arms and toe bolts, Hotchkiss front and rear sway bars with whiteline endlinks (rear only). currently i am on high height setting on coiloverd for winter.
the noise is coming from the front driver side when I go over bumps. before making this video, I lubed the front driver spring's base and top section. have a look, any ideas?

Its the cheap coils and and speed involved going over the hump. The coils are inexpensive and cannot rebound quickly enough for that large of a bump.

Teins don't make noise . Could be the top mounts might need to be replaced if so u can buy from kyb for like $30 about.

LMAO how's it a blanket statement if it's from my experience? If anything ur feedback sounded more like a blanket statement. Even op said his didn't make noise prior.

on Facebook group, someone said that his hotchkis swaybar bushings made such noise and after he greased it with gun, it went away. my bushings were lubed when i had the swaybar installed, around 2 years ago. could that be a reason?
and top mount you mean, top mount of the coilover? i think i used my stock top mount with my teins. 69k miles, they can fail so early? :/

saywat?

Yea could be the sway bars too . And yea the tein basis reuses the stock top mounts. Hard to say I'm curious if you could test the sway bar theory by unbolting them jus to test and weed it out.

hmm, i will try it tomorrow. when you say unbolt the swaybar, i am taking it as unhinge it from the front end link? i would try the driver side only, thoughts?

saywat?

iTrader: (3)

Swaybar noise commonly occurs with the bushing so I would unbolt those 2 and see what happens. If u suspect the end links take off the entire bar.

yup, my driver side sway bar bushing had all its grease dried up. the noise disappeared as soon as I unbolted the bushing.
Not sure what type of grease I should have used but at this time I had my brake grease handy, I used that. I think I will need polyethylene bushing grease, a sticky silicon-based one?
any advice on which grease I should use? I next time when this problem appears, I will use the correct grease with a grease gun.
