Anyone have any useable info on a Ford 10.25 rear axle with disc ?

what exactly do you want to know ? im running one.

here is some specs on an 85 model 10.25
ring gear diameter :10.38
pinion shaft length: 10 1/8
pinion shaft spline count: 31
axleshaft spline count: 35
axle shaft diameter :1.5 at the splines
hypoid offset: 1.50
gear ratio range:3.08-7.17
brakes: drum
weak points: the spline length on the yoke and pinion is insufficient. this causes the yoke to wobble and move causing wear on the pinion bearings affecting preload.which leads to leakage through the splines and pinion seal. this will eventually cause pinion bearings and ring and pinion failure.

fixes: buy the longer pinion with your gears and longer yoke.
ditch the stock carrier for a locker. apply silicone to the splines on the yoke before assembly to seal the yoke to the pinion shaft to stop leakage. once in a while check to make sure the nut is still tight. also get some shouldered ring gear bolts from a dana 70. the 10.25 bolts can back off and come loose.
overall , im pleased with my 10.25 . but i have done all the upgrades. and got my disc brake conversion at blackbirdscustomtrucks.com
