Reply With QuoteOn the hoist you should be able to have your hand on the CV while turning the wheel slowly to determine if the noise is coming from the CV or the wheel bearing.

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.

SubscriberIf it's on the hoist, the quickest way to find it is to run it in gear while placing the point of a mechanics stethoscope on the bearing housings as they are rotating, if they all sound the same ( smooth static noise ), then they're probably ok.
Some of the CV's may feel "notchy" as they are being turned while at maximum articulation while it's on the hoist ( assuming 2 post )
Your "light knocking noise" though, may be more likely bushes if it is when going over uneven ground.

SubscriberWheel bearings don't always show up noisy on a hoist. They need to have a load on them to make a noise, eg. on the ground driving the vehicle.
Also, why is this in general chat and not the D4 section?
