Hi all (Discovery 4 2012) was swapping some wheels over today on the hoist and thought I better check out the light knocking noise underneath. Turns out the LH rear wheel bearing or CV is notchy while rotating that wheel. There's no free play at all either in the hub or the CV. It's just audible inside too going slow at idle. Is it common for the rear CV's to wear out on D4's? Hasn't had a hard life. Just wondering whether to get both a new bearing and a CV driveshaft rather than wait n see til I have it apart.
Cheers and TIA.
