I love the greasing system you have and thats all I would buy again! Being a tandem I am betting you have a tapered shaft and it will be like 1 1/16 out side and 1 3/8 inside, just take them off and take with you to the store they will tell you. Why are you changing the hubs?? 99% of the time all you need are the bearings and seals. Much Much cheaper! Good Idea to have a spare hub incase. also anti seize the lug nuts so they don't rust on! after 5 years is the salt mine just spun right off!
