Sure, it's been a while and was so easy I don't remember the details..

Rtv= gasket maker.. Get a tube at Walmart. Think I used black.

You may also need to disconnect the diff lock, it's on right side.

Thank you if the weather is good tomorrow I think I will jack it up and take a look

Do you remember the type of Harbor Freight puller you purchased? I assume this was for pulling off the bearings?

Yep.

B7500 HST about 1400 hours - when I was grading my road I went around a corner and I heard a big clang and the motor stopped but started back up again but the rear tires seemed locked so I jacked it up and then they were free wheeling. When I drive down the gravel road the ride seems different like the wheels are not rolling smooth. I have had issues with the rear hubs and shearing the pin in the back many times.

Not sure about killing the engine with HST.

The hubs must be worn out. Mine have been cleaned and re-torqued ONCE and have stayed tight since.

I agree the hubs are worn out and will need to be replaced including the bolts and wedges in the hub

Be sure they are CLEAN & lubed. Pull all the parts outs, clean, lube, tighten, run it, tighten at least 3 times and they should stay.
