    I've actually had good luck with my 2012 Karavan with maintenance free KNOTT hub/bearings. Never had a problem, just thoroughly rinse after salt water ramping. If that water tight seal gets compromised, then your going to have issues.

    BUT I did make sure my next trailer for a new ski was a Triton which is like a luxury car ride compared to the Karavan Lol.

    Im at the point where i think i should just buy another trailer. Magic tilt with knott axle is just not easy to fix. It could be fix but do i wanna deal with this again?? It just doesn't make sence.

    Why don't you just replace the whole Knott bearing with factory parts? Prob like $250? If you got the cash and want to sleep at night by a brand new trailer (not Karavan). You can get one for under a grand.

    Ok guys gotta share this with you . I got it fixed i went to the auto parts store spend around 2hrs trying to find a seal for the back as rlace already had the bearings parts figure out in a earlier post so here are the numbers for the seal i used 473560N from national oil seals and for the bearing set35 for duralast. Hope this will help other people at the time when they got to replace their bearings. Have a good one thanks for the help!.

    Looking to do some bearing maintenance on my trailer. I found I can buy the complete hub assembly from Knott in Wisconsin. The assemblies are only $25 each, includes nut, seal and all. May be worth a call if anyone needs them. Knott part number is 6B 4065.302

    Thought I would share my experience with these bearings. I just replaced both hub assemblies on my Karavan with new ones after 3 seasons of all salt water use. I had about 3200 miles on mine based on my truck's trailer tracker. After seeing the posts on failures on these I figured it wouldn't hurt to do it and see the condition of them.

    I was pleasantly surprised with the condition of mine. In pretty good shape aside from some superficial rust and no water inside. I think I could have gotten a lot more out of them. I will keep the old ones as back ups and next time just buy the one use axle nut only ($4) so I can pull/inspect and then put them back on. I always keep the back side hub seal sprayed with Fluid Film. I think that helped it a lot to keep that seal waterproof.

    My bearings last about three years with intermittent salt water use. You are smart to spray the seal area with a rust inhibitor. I believe this is why mine fail-the surface the seal rides on corrodes, making it abrasive. Before I install new hubs I use a lot of emory cloth smoothing this surface and I still can't remove all of the pitting. The axle may have a serviceable sleeve but I haven't looked into that. Since the hubs can be purchased for about $73 each, I don't think it's worth trying to design a new system.

    I contacted https://www.autoflex-knott.com/contactus and just ordered a brand new axle with grease able hubs included for my single place Karavan trailer. They said it was an EXACT replacement to the Knott axle/hubs. Price: $142.85 and they are shipping it to me in SE Michigan for $42. No more "sealed" bearings to worry about.
