So while replacing the swing arm bearings on my 86 250sx. I noticed some slop in the differential. I tore it down to flush out all the old nasty fluid, and really discovered the slop. So, when i aquired this SX, i was about 16. The rear diff was in pieces and i had to rebuild it. Ive always noticed shaving in my fluid, so im guessing my gears were worn initially and i never really noticed. Being 20 and working at a machine shop now, i know what to look for, and have alot more help. The bottom of my pinion shaft is worn out, and sloppy in the needle bearing, which wore out the pinion bearing prematurely and caused more damage to my gears. So, long story short, new gears and a new bearing kit are in order. Any help locating new gears, or possibly a differential in good shape would be appreciated! Thanks guys
