A squeaking noise from the rear left tire when turning is typically caused by a worn wheel bearing. The bearing supports the wheels as they turn.
Could also be the brake pad "squealer" letting you know it is time to have the brakes serviced.
If you lowered the car or had suspension/strut work done you can be rubbing The body in the boot?
Wheel bearing?
maybe the flap obove the left weel has com loose something youv left in te boot and forgotten about
The wheel bearing
Sounds like you've got a bad driveshaft.
CHECK THE EXHAUST.MINE WAS HITTING THE BODY AT BOTTOM OF REAR FENDER
Sounds like the bearing may be shot in the wheel.
If it happens only when turning corners, this is likely to come from the differential. A ball bearing problem would make noise all the time.
You probably need your bearings repacked
The wheel bearing?
If the "grinding noise" is present while cornering left and all but disappears when cornering right, my experience* says it's your right rear wheel bearings needing replaced. * My '96 did the exact same thing another thing to check is my exhaust pipe would rub the rear suspension on the passengers side and make an awful noise only when turning left and it would be worse with more weight in the car
Its not anything to do with the fact the vehicle is 4wd. The rear differential needs an additive added to the gear oil to keep the noise down. Go to any auto parts store and they will give you what you need. Also check the gear oil level it is probably low
