Customer Question

I have a 2009 ford f-150 4wd that has a high-pitch whine whenever I turn sharp right while moving. It doesn't make a noise when the truck is sitting still.

Hello, does this noise sound like it's coming from the front end?

This il usually ends up being part of the wheel bearing. On the inside of the wheel bearing where the from cv shaft goes are needle bearings. These needle bearings get very noise when they dry out. You can corect this by removing and greasing the needle bearing with wheel bearing grease. This will correct the noise issue you are having.
