Hi,
I have just over 23,000 kms now and have noticed a kind of rubbing noise on larger bumps and off roading too.
I seemed to be able to slightly feel it through the steering wheel too, but I'm not sure if I was imagining that.
I had a look underneath when I was doing the oil change, and noticed that the front sway bar looks like it had moved sideways through the clamps, enough for it to hit on what I think is called the bottom control arm or joint.
I haven't re-centred it yet, but I'm pretty confident that it is the cause.
If so it should be easy enough to fix, there was only two bolts to loosen off on the clamps, then re centre the bar and maybe put some locktite on to stop it happening again.
I haven't got any oil leaks yet. touch wood.
