could be a front cv joint a front ore rear drive flange a half shave or yes a diff problem take it out off difflock start the engine put it in gear then look under the car and see what propshaft is spinning then thak the black caps off the end of the hubs and see if one of them is spinning my bet is a cv or a drive flange
wtf is a half shave?
why would it be a front cv joint if hes got no drive to the rear diff?
your easiest way to tell if its your rear diff or half shaft is to simply remove each of your half shafts if one comes out with the end snapped orf then theres your prob..
if it is my transfer box how much am i lookin at for a new 1 or can i get a recon 1 and how much would i get charged for it to be fitted thanks paul.
