B4 ball diff.
I just dismantled my SC10 and took the ball diff out. The balls had melted into the plastic gear they are mounted in.
It would appear the ball diff was to wide for the gearbox case and it had bound up when built putting pressure on the diff, melting the grease that got thrown out and then got so hot the balls melted in to the plastic.
It used to be a gear diff, are ball diffs wider? Do they have different bearings?
The gear box case was fine, without balls it fitted and the case closed nicely.
It was only when fully built that the gearbox case wouldn't shut square and bound up.
I'm going to get another gear diff I think, it's not a race truck, I just need reliability.
Any thoughts on my issue?
