Pajero 3.2 DiD Gen 3 or Gen 4 rear differential

When I bought my Pajero I got this spare diff with the vehicle. I have driven my vehicle for two years now and have had no problems with the diff I have in the vehicle. So I am selling this diff now. It has oil in it and none of the seals are leaking. I have done the two tests as per manual and there is now free play and the play from the driveshaft to the side shaft play is also in spec. In Gauteng these diffs are selling for R8500 and you can get mine for R5500 onco. As I have no further information the diff is sold as is.
