Hey I was told to at least get a lsd for the front cause they are hard on CVs I have chosen an ARB air locker for mine & since fitting no more problems with braking CVs. its to do with traction when the wheels slip & grip again it puts strain on CVs bit with a locker both wheels turn equally even if 1 is off the ground so no gap to take up.. try that it worked 4 me & I like to play hard a lot.
