Having issues with my scramblers front diff ever since I broke an axle.

went for a ride and broke an axle, bought a set of Rhino axles for the front and replaced the stocks. I noticed a stiffness in the front next time I tried it. I took apart the front diff and found the bearing had flat spots, my Sprague was damaged and the armature was bent.

everything has been rebuilt and all new. now the front binds when I’m in 2×4. even with the bike in Neutral, rolling down a slight slop, it will come to a stop like the front brakes are being applied.

runs ok in 4wd. anyone ever any ideas before I pulled the front diff out again?
