Grinding cracking pop

[Cbark2305]

Last week our 07 Yukon Denali starting making a cracking pop and grinding noise out of the front passenger side wheel. Today the abs and traction lights came on. Sometimes it makes the noises and sometimes it doesn’t. I’ve pin pointed down to either the wheel hub or cv axle. Any tips on figuring out which is the problem?

I would think if you turned the wheel to extreme right or left while accelerating and the sound goes away, it’s most likely a wheel/hub bearing. If the sound is still there it could most definitely be the CV axle joint. Is the boot torn around the suspect CV joint?

No the boot is perfect. Nothing looks out of place at all. I got under and tried to jiggle the axle and it’s no loose or anything

Jack it up and see if there's play in the wheel 12-6.

Alright I’ll check that out tonight or tomorrow

If there is then it’s the hub correct?

Usually, yes. Also, the sensor is in there, so I'm guessing that's your problem.

I was just backing up and turning the whee to the left and the grind was really really bad

Yeah, if it's the hub, they can get squirrely on you really fast. When you have it in the air to check it, spin it, and it may be really obvious if it's grinding that bad. Make sure your pads aren't dragging on the rotor, etc.

I don’t think it’s the pads because I just replace them a few weeks ago and it’s not a constant grind.
