The bearing thing was to stop it pulling left... I'm not sure of the terminology but I will try my best to explain... It was at caloundra suspension n exhaust when I was quoted 600 to supply n fit.... The cradle or housing for the bearings is slightly egg shaped and thicker on one side than the other which as u rotate it the camber is slightly adjusted???? I dunno I'm a bloody plasterer not a mechanic... Also the back wheels are not tracking the same as front??? Is that adj through the panhard???
