Hi folks. I have a 2002 GU. Last time i went to the bush for a wheel my drivers side started making a clunk clunk clunk noise. It is only when engaged in 4WD. I have swapped my hubs over and the noise stays on that side. Swivel hub has also now started leaking a little oil. Would this be a bearing issue? Or will it be the CV Axle that i need to replace. If i am going to replace axle i will also replace all seals and bearings. Any help on this would be really appreciated.
