To recondition a transfer box. I recently changed the diff in my evo cos it was making a whining noise. I split the casing open to check what was wrong & the only thing i could find wrong was 1 worn bearing which had play in it causing the main wheel inside to rub on the casing hence all the swarf that came out when i checked the oil origionally. Any ideas where i might get a new bearing to re-build the box?
