David, I'll give you MY account of my Scamp
and how I feel about the trailer bearings. This is NOT advice so as my disclaimer...do as you wish, but here's what I've done so far.
2010 13' Standard Scamp
bought brand new fully-loaded weighs 1750 lbs apx 1900 lbs MAX loaded ready to travel. My running schedule has been like this... avg 4 camping trips a year since 2010. My trailer has a documented 9000 miles on it.
My maintenance schedule has been... NO grease, NO pulling the wheels since I've owned my trailer. My hubs NEVER run hot...never have. I spin the wheels before taking them off the jacks...they're VERY smooth and coast very well without any "notichiness". I pulled the rubber covers off the EZ Lubes and there's plenty of new-looking grease (not black/burned) there at the opening...both sides! I check the hubs regularly between stops with my IR meter and hand-feel. The tires
are the same that came on the trailer... DICO's. I use a magnifying glass to check for dry rot. Their manufacture date is 2008.
WHY do I feel comfortable with this? Well, outside of speaking with Floyd on the phone about it, AND Dexter (more details if you want), my axle
is a Dexter 2200 lb. cap. Loaded, the max load is 850 per side (rated 1100 per side!). I drive 62 mph when towing. I run 50 lbs pressure. When parked, my trailer stays up on jacks and under a fully shaded carport. I spin the wheels when I walk by which is quite occasionally. I also check for "play" by grabbing the wheel/tires on each side and performing the test. I can say that the ONLY maintenance I've done on the axle/bearings/tires/brakes since I've owned my trailer is adjusted the "Street" side brakes
I've gone head-to-head with Dexter engineers as to WHY they tell people to PULL their wheels EVERY year REGARDLESS of the miles which is TOTAL nonsense!! I had one honest soul tell me they know they wont be getting calls about their axles...sheesh. Their main target for this...and it DOES make more sense- is boat trailers going in water regularly. THAT is the reason they developed the "EZ Lubes". When you do as it's designed, it will push any water out of the bearings and out the front. I'm more concerned about people trying to do what's right but are not professionals pulling the wheels/bearings and getting more contamination inside, over tightening, wrong grease...etc.
I'll more than likely get blasted for this post but that's fine. But I have to ask, why doesnt GM, Ford, Nissan, Toyota not tell us to pull the bearings on the front wheels of our trucks every year regardless whether we drive them or not????
How you load (NOT OVERLOAD), drive, store your axles/trailers is the true story of how you should maintain your axles and bearings...in my opinion. And finally, I KNOW my axles and tires
have a HUGE safety factor built in with the load I carry with my trailer vs the capacities stated. But if a trailer is loaded to the max on the axle
load and tires
, to me, one is flirting with disaster and all I just wrote will/would not apply to me or anyone else.
