Well it quitened down, but this morning its louder than ever.
Checked the fluid, and even just after the drive to work, it was sitting around the minimum mark, will see what it is later and top it up if its low, but from what ive heard, its time to worry if you have no fluid on the dipstick at all, so at least it doesnt appear to have a leak.
Something just crossed my mind though.... i had the car lowered 30mm about 2 months ago, and all was fine. Then i fitted the rear arb 2 weeks ago... i honestly cant remember the noise before that. Is it possible that the lack of roll has caused the front arb to rub the driveshafts??
