Hi im new to the forum, Ive had my 04 uk Z since september 08 its now done 27k no major probs, just the usual, wind noise, heavy gears and clutch, tracing paper paint, enormous smile, admiring glances etc , however the other morning when getting out of the car i turned the wheel which produced a knocking noise, turning the wheel quickly back and forth continued to produce this knocking. Concerned this might be bjoints, bearings or a rack problem, any ideas i have an extended warranty and hope im covered!!
