I have a bad outside axle bearing and broken teeth on my bull gear. Is it easier to change the whole final drive or replace the affected parts.

If it was my tractor I would change whole unit from diff housing out, does require removal of brake shoes.    Final drive assemblies are inter changeable left to right.

Believe you may have to remove the brake shoes for the drum to clear the housing

I have several finals all apart and on the shelf or the assembly with the brake drum off. the only difference is the fender support casting between WD and WD45. I have those also with no broken bolts in the casting. Also have resurfaced brake drums and all the brake parts. For Sale!

 The two castings never get seperated. The axle pinion comes out through the brg cap and the bull gear drops out the bottom.

If I’m not mistaken, the wheel axle on the WD45 is slightly stronger than the WD, even though they are interchangeable.

I think when the axle failed, the tire/wheel fell off the tractor.
