| Help air diff Have a problem with diffs on 406, u900 mog. The diffs have not been locked in for a long time, but the front one locks up, but the rear diff does not! can i give the diff casing a bang an see if it pops it out? or take the air pipe of at the rear diff an see if air is coming out of the pipe? An if i disconect air pipe to diff will i have to blead the air system? Thanks |
