Suspension Issues

[AikenLugonn]

I have of late been hearing various noises in my v36 coupe which seem to be related to the shocks. When I go over big bumps (as are common on Sydney roads) I hear a rattle. I now also have what sounds like a worn out mattress sound that is annoyingly common, and occurs over nearly every little flex of the suspension. I left the car with my mechanic, who despite looking quite carefully, was unable to locate any obvious source of the problem.

I have an adjustable coilover sports suspension set, that my mechanic says has no branding on it whatsoever (and thus likely a very cheap make - it is what the car came with).

Wasn't expecting this issue on a car with 68000kms (legitimate)...is my only option to replace the whole lot (shocks/springs etc)?

Is this a common v36 issue?

My car (V36 coupe) arrived with lowered aftermarket suspension. Very high quality but not even close to being able to cope with Australian road conditions.

I now have a full set of MCA Coilovers made right here in Queensland and tuned for life on our roads. Cannot recommend them highly enough!!!

I had the same issue recently with my V35. Turns out it was my rear sway bar end links.

Is that a cheaper option than just switching to non-sports suspension?

Personally I wouldn't use non-sports suspension. Too soft and wobbly IMO.

Check the front lower control arm bushes. Very common on V36s and on the sister infinities... You won't be able to see wear in the bush but if you glide slowly (slow slow walking pace) and jam on the brakes you might see the wheel jump back an inch or more (towards the rear of the car)... This is wear in the LCA bushes.

Unfortunately if it is this then it's not cheap - they don't sell the bushes separately and you are up for two new LCAs. I just did mine at a cost (NZD) of $1700ish.

For what it's worth I was a little skeptical before but it noticably improved steering and braking.

Hmmm?? I have recently replaced these bushes on my 2003, V35. Check out Spares Box.com.au They sell Super Pro, I have just done a quick search of the site using a 2007 car as an example which should cover the V36, and the product is for sale for < $200 AUD\set. Part No. SPF2847K Their website can be difficult to search on. Probably best look it up as a 350Z
