I've been told that a few GT transaxles have a limited slip diff and I wanted to see if this can be done on a 2500 peerless. This is one with a diff carrier and two pinion gears. Apologies if my terminology is bad, I'm not the strongest with final drive assemblies. I'm sure somebody's going to ask why I wouldn't lock it, and the reason is that a locked tranny on ice is not great. Believe me, my grandad drove a 10 wheeler plow and even those don't steer good with a locker. Anyway, I'm sick and tired of spinning out and I wanted to see if there is ideally a drop in assembly (probably doesn't exist but I thought I'd see) or a beginner-grade modification that can be easily performed. Probably not going to try this in the near future because these 2500s are quite the task to split. Anywho, wanted to see if there was any ideas out there.
A limited slip diff is basically brakes on the spider gears that don't fully stop the gears from turning. You get alot of drag on the spider gears that don't completely stop turning when working the way they are suppose too. With that said, when the diff part is together in your 2500, there is a certain amount of clearance between the gearing inside the diff. Maybe cram some leather washers in there, or rubber washers, or plastic washers in there. To act like a brake for these gears, to put drag on the spinning of the diff gears without damaging them. I would think this idea would last for a while but would eventually require maintenance on replacing whatever you use for the material.
What about a disk brake, on each side, outboard of the transaxle? Is there room to squeeze one in? That is how a lot of old tractors worked, a split brake pedal would allow braking the slipping side.
Here’s a long discussion of how to do it and how it works.
