i changed the oil in the rear drive today its got 12k on it and it was spotless, i felt quite pleased but being an 08 gsa theres no need to tilt the drive to get the oil out but i thought its a good idea to have a look at the pinion bearing, im glad i did the driveshaft was covered in rust the uj's seemed ok but it looked a right state as did the pinion, it cleaned up ok though, ive seen photos of driveshafts years older than mine and they look brand new, so god knows how the waters got in
