For the past few days I've heard a feint clicking/knocking noise coming from just in front of my feet when I accelerate and corner. Reading threads on here, I'd put it down to a worn driveshaft - however, I've just taken both front wheels off and there is very little movement in both front shafts (1cm at a guess) and the wheels aren't moving in and out when I do.The only thing I've noticed is the inner CV joint on the drivers side has grease all over the shaft behind it but I can't see where its coming from- could this be a cause? I assume it probably is.I've come across numerous methods of changing the shafts, with the drivers side seemingly apparently being the easier of the two to change - so am at a bit of a loss how to tackle it...
