Grinding noise while in gear and turning right

[Flyn]

Guys, my Buick Park Avenue Ultra has a grinding noise from the motor/trans area. The noise occurs only in gear while turning the wheels to the right, either moving or standing still. CV Joint? Thanks in advance!

grinding noise?!
you're probably hearing the sound of Big Poppa Pump's miniscule brain trying to function at a normal level.

I'm guessing CV. But wheel bearings as well

The grinding doesn't occur unless the car is in gear. It occurs even while stopped and just turning the wheel which makes me think it's not a wheel bearing. I had the trans rebuilt a year ago and both wheel bearings have been replaced within the last couple years.

Anyone know replacement cost? I'm guessing a couple hundred?

ball joint?

bushings needing lube? :naughty:

Crank walk. lawl

Looks like a drive axle is only around $70 so I may take the car to a mechanic tomorrow and get it diagnosed. I'm hoping the problem is in the axle itself and not in the trans.

The noise is a prolonged grinding sound sort of like gears not meshing correctly. Turning the wheels to the left does nothing. Only the right turn produces the sound.

Why?

I don't think so since it happens when the car isn't moving.

Crank walk. lawl

I really doubt this is the cause. Crank walk usually shuts a motor down. Plus this isn't a DSM car.

Thanks for the responses so far, guys. I appreciate the input.

Very helpful...

I hope its not something internal but it could be a binding CV.

Thanks, Rich. Since the motor runs fine when in neutral, I think it's most likely either trans or CV related. I'm guessing it's either in the boot or where the axle meets the trans. Hopefully CV since I have no idea what's necessary to fix it if it's trans related.

Probably the CV joint, but it might also be a broken sway bar.
I had a broken sway bar on an old FWD car that I had and it caused the CV joint to grind when turning left. After replacing the sway bar, noise went away and it was fine.

 

[Flyn]

Thanks. I'm getting the car on a rack today. I was wondering if a broken motor mount might cause the symptoms and the mechanic wants to take a look under the motor.

Looks like Mook wins the prize. The subframe bushings on the passenger side are worn out. I PB Blastered the bushings today and the grinding is almost gone. Getting the bushings replaced next week.
