I recently purchased a Jayco 806 series that I basically tore apart to start a full rebuild ( building a camper on the frame ). Just ordered bigger rims and tires and would like to know more about the type of axle system I have. The axle from what I've been told is a rubber torsion axle, it had a sticker on it ( now removed ) that read it was built by Phillips with the Dexter " D " logo on it. I've searched all over the net comparing the part that's mounted on my trailer and have seen similar grease housing hub units but have yet found any that are identical. As you can see in the pic, mine has some sort of ring/spring around the interior of the housing, have yet to see any like this one anywhere on the net that is made by Dexter,close but not exact. Also the plastic hub caps read Haul Master, probably doesn't mean much as someone could of simply put them on there. Is this a Dexter EZ Lube? I'd like some info in order to do proper maintenance on it. Thanks in advance for your help!
