4020 load shaft seal

[4520BW]

look my dad's 4020 shaft seal are leaking a little. I have done several using Deere seals but everyone on here says buy from Boling. What is all involved in the installation process of the Boling kits?

The boling kits have the o ring in the metal bushing. Use them they work good. You still use the original type seals and shim up any side play. I usually put a new shaft in too. I hate to do this job over.

John Deere as well as A&I offers the updated bushings with the O-rings too. I would replace the load shaft too.
Boling gets their load shafts from A&I

What year 4020?? Later models came with the "new" style bushings and seals from the factory.
