Hi Guys,

Since buying the 380 vrx I've had this weird sound which seems like it is coming from the rear right of the car (drivers side rear) when i turn hard left. It sounds a little like when you have springs that aren't seated correctly. Has anyone had a similar issue in their 380? I'm trying to work out what it is.

Also when I'm doing this, it almost feels like the front of the car axle tramps. The magna doesn't do this and the 380 doesn't do it when turning right, only when turning hard left.

Any ideas?

Check the rear sway bar mounts & bushes.
Not just the main D brackets & bolts, but the spindly looking linky bits on the ends as well (I have NFI what they are called!).
The bushes wear out fairly quickly and lead to clunking, creaking & groaning noises, sometimes a D bracket snaps right through (but so far only confirmed to have happened with Selby heavy duty swaybars), and I once found that on my car the nuts holding the 'spindly bits' had become quite loose.

KJ.

I have had a crack/clunk for some time coming from that spot. Took it to my mechanic who at first thought it was a spring not seating properly but not the case. I thought it might be the rear bumper quarter panel flexing. I cant trace it but its bloody annoying. The car is on kings lows and maybe a shocker on way out.

turn up your stereo its too low

Sorry just to clarify, the car doesn't axle tramp, but it bounces up and down like when you axle tramp.

And yeah it does sound like a spring which isn't seated properly. The car has done 143k kms, so could be worn shocks? Thanks for the suggestions, gives me a place to start looking. If there is an issue with my sway bar, is it obvious what i'm looking for?

No direct suggestions about the cause, but a couple about trying to find it:
- sounds like that quite often appear to come from a different part of the car than where the problem is (metal is a good conductor of sound);
- find a way/place that you can repeatably provoke the sound;
- if possible record the sound;
- find someone who has good directional hearing and either train them from the recording or by provoking the sound;
- let your observer listen from both inside and outside (where possible) the car while you provoke the sound to try and narrow down where it is coming from.

Being able to repeatably provoke the sound is key to speeding up the process.

i love you man

OK so got my new berklee muffler installed today and the noise is gone :S.

My old muffler must have been loose or something? Is this possible?

I reckon your stock muffler was moving on the soft stock mounts. Hard turn left = muffler "turns" right (inertia) = clunk.

Having done six different exhaust set ups so far (# 7 coming soon!) I can tell you that the stock 380 rear muffler rubber mounts are as soft as butter.
