3 Suggestions.. Try two of them.
1: Lubrication: As per the owner's manual (if you need a new copy of the manual visit Blue Ox Products Home Page
2: Pender, NE.. There are two facilities you might want to visit in Pender, NE. First: The Blue Ox company campground, It is a nice small campground (perhaps 20 sites) full hook ups (50 amp) Wi-Fi, and you will LOVE the nightly rate (When I was there it was $0.00) Second, the factory next door.
NOTE: the factory is on one road, the Campground is on the road you turn off of to get on the factory road.. GO TO THE CG first.. Then hike to the factory (Go past the road the factory is on)
3: Quartsite, or another large RV rally where Blue Ox Factory reps show up.
Tell them, what you said here.. See what they can do for you... Rumor has it they are very nice.
OH.. Been to Pender.. They were indeed very nice.
