Benno has done this before, about 3 years ago on our previous 19ft Jayco trailer.
Working on the wheel hubs not all working positions are comfortable.
To lift the trailer Benno used a 10 ton hydraulic jack and after lifting,
secured the axle with axle stands.
The Dexter Axle Operation and Service Manual that came with the Jayco White Hawk trailer explains the wheel bearing lubrication process. One page is dedicated to the approved grease sources. In our case Benno used "Valvoline Multi-Purpose GM" grease that he purchased at the
TSC store in Leamington. The grease nipple is hidden behind a rubber plug which has to be carefully removed first.
Notice above in the picture Benno is rotating the hub with his right hand while pumping the grease gun with his left hand. Rotating the hub prevents the grease gun pressure to bust the rear seal. The rear seal contains the grease to the wheel bearings and prevents the grease to get onto the electric brake system.
Don't loose the rubber plug and don't forget to put it back to the metal end cap.
It keeps the road dirt out of the wheel bearing.
Picture below wheel hub with the rubber plug back on.
Benno used theopportunity while the wheels were off to give them a good wash. After installation he torqued the wheel nuts. In our case it is 14" wheels and the wheel nuts are torqued to 115 - 120 FT-LBS. The tire pressure will be checked just before we are hitting the road south and during the drive frequently during pit stops.
I might now spend more time indoors and on my computer so updates and comments will be more frequent. (I hope so)
