This is my rear gearbox big bearing modification (8x16x4).



Machined front side, uses 8x16x4 bearing.



Machined rear side, uses 8x16x4 bearing.





The stock pinion bearings are 5x13x4, that's too small for me



Steel bushing, 5x8x8mm



She's ready to run! I ended up pressing in the steel bushing with a vice on each side of the bearing, it's not moving and is rock solid. Everything spins smooth, ready to rock & roll 👍
