I used to work in a driveline shop. Had all kinds of weird noises come in on occasion. Groaning and grinding noises when turning usually resulted from one of two things.

The wheel bearing is going (sounds like your problem) The dynamics change when your making a turn so the load on the wheel is different and the normal to the rotation is modified on the direction of travel.

The inner CV Joint starts with a goan and then starts vibrating.. etc etc.

I'd bet on a wheel bearing though.
