Outer Limits 4x4 Board

i got a gu patrol.

when i engage 4wd, in the front right hand side wheel there is a noise comming from it, almost like tyres scrubbing, but they are def not. its more when i plant it then get of the gas, going over whoops on the beach etc.

when i disengage 4wd the noise is still there, but then i stop the car, reverse a few metres then take off, and its all good. could this be the cv joint or what.
cheers

could be the cv, when reversing if auto hubs, this disiengages hubs.
Would check cv joint might be worn or out of grease

if its lifted high it could be front shaft vibtation when coming of load. my gq does this on the beach over humps

Probly the front left auto hub as thats what happened to mine.
