Your left front wheel bearing may be defective. When you turn right you put more weight on the left front wheel. It can also be a problem with your brakes. May be you brake pads are worn out. You need to inspect all this.
posibly needs a new axle cv is bad
More then likey it is either the left are right front wheel bearing that is bad.
It might be a CV joint, when the CV boot is ripped and the grease is partly gone , then it makes noise.
Worn right front wheel bearing.
Possible wheel bearing, see if noise changes on left & right turns.
Worn out bushing or steering joint probably.
Are you sure the noise isn't in the front. Sounds like a right front wheel bearing,which is a common problem on these vans.
if its when you are breaking it is possible it could be a rotor if you hear like a roaring or grinding noise coming from that side also could be a wheel bearing
Ball join lubrication or change!
that is either your front right wheel bearing or your coil spring is turning need new suspension..$$$$
i would first balence the tires then try replacing the wheel bearings if the noise is coming from a specific area on the car In example left front, right front etc.
when turning or when ridin?
