I had one wheel bearing going bad lots of play. At the same time I was having my RCV axles being serviced. I installed some China drive works bearing/hub assemblies and after the first test drive with just axle stubs and it sounded like metal popcorn.

I returned those wheel bearings and installed a set of Timkens. The vehicle still makes the god-awful grinding sound. Popping or binding not sure how to describe it I have will have a link to the video.

When the front end is jacked up both wheel spin perfectly no sound. Shocks, wheel-bearings. brake rotors and pads were replaced all at the same time. I have everything torqued properly according to all data. Any ideas?

Are you sure it is coming from the front? Do you have CV shaft in with but tight? Wheel isn’t rubbing anything? Just a few thing i thought of

2wd or 4wd didn’t matter. Full cv axles or just stub ends I tried and still makes the same sound.
When The front end is jacked up I can spin the tires and it makes no sound it only makes a sound when the weight is applied and you’re driving.



some thing I’m wondering is if the CV axle nut is too tight? would that cause any issues?
