When i hit 45 mph in my 95 z28 i get a rubbin vibration from what feels like the pass front wheel when i turn a little to the right, like when i go around a bend. It gets more noticable at higher speeds. Its not there below 45mph and is only when the wheel turns slightly right, its not there when going to the left or straight. Any suggestions on what it could be? Btw im on stock rims

 

Check for play in the wheel bearings. They are part of the complete, replaceable "cartridge" that includes the bearings, spindle and ABS sensor.
