Ranger Trail Cool Hubs
« on: February 03, 2003, 02:41:13 PM »
Dad and I both have Rangers.  Mine is a 95 392 and has regular greased trailer bearings.  I usually have to have them packed twice a year as I average between 5,000 and 6,000 miles on the trailer in a year.  Dad's is a 1999 519VS and has Cool Hubs on the tandem trailer.  Supposedly according to Ranger, these are 30,000 mile hubs.  He pull nowhere near that.  Maybe 3,000 per year.  1 has been replaced and 2 have been rebuilt.  They don't seem to be lasting like promised.  Have any of you had experience with this type hub (Oil filled as opposed to greased bearings)?  The first time, we took it to the Ranger dealer and he said they had to be replaced as a unit at a relatively high price.  Something like $200 as I remember.  I have since found they are the same hubs found on Railroad trucks and some other medium duty trucks.  They can be rebuilt by a competent mechanic.  Still that is relatively expensive because you have to buy new seals.  I know some of the other manufacturers have used this style hub as well, and I haven't heard much good about them.  Just wondered if anyone else had experience with them.

Cool hubs

Hi Skip
I have a 392vs with cool hubs. Had the same thing happen. Cool hubs should last for years. The problem was a Bent axle. Once I had an Alignment shop straighten the axle the cool hub problems VANISHED.
Any alignment should be able to do it for you.
If the axle is bent to the point the wheels face in or toed out the hubs do not last.

I don't have much experience with boat trailer hubs but have been a car/truck/4x4 mechanic for years and have had problems with front driving axels with water and have solved many problems using water proof grease but my biggest improvement is using a "moly" additive either grease or oil additive in the lubricate makes a big difference in reducing friction and wear reducing heat too. If you do a search for moly many distributors will come up with all types of "moly" greases and additives of ll kinds its well worth the extra money everything lasts longer it just doesn't wearout. It fills the pores of the metal to the point there is no metal to metal contact just the lube contacts each other no friction means no heat thus no wear. Awesome stuff for sure.  There is additives for your engine/transmission, differentials I even use the paste form in my fishing reels too.  Check it out "MOLY" !!!!               BigBill

That Maroon sled I'm standing beside might look familiar, its a 392 as well.  I sure do like the way that boat fishes.  It's not as high tech as the later model stuff, but it gets the job done and is a lot comfortable to boot.  Seems like Ranger's quality was a little higher back then too.  I didn't really want a dual console when I bought it.  Fact is I passed it over for 6 months because of it, and so did everyone else around here.  Dual consoles may be the rage elsewhere, but they aren't in this area.  You can't give one away till you own one that is.  I know I would hate one in a shorter boat, like an 18 footer, but with the 19.5 feet of the 392, it gives you more room and you don't mind the console so much, and that glove box.  That's the handiest box I have ever seen on a boat.  Its big enough to stuff a bird dog in, and accessible standing on the ground.

Back to the hubs, The tires aren't showing any indication of a bent axle.  They are a little worn, but then again, they are 4 years old.  The cool hubs are on a 1999 519VS.  I guess it might not take being much out of align though.  Is yours a tandem or single?  Dad's is a tandem, and mine's a single with regular hubs.  It seems like it happens on the rear axle more.  I wonder if it has something to do with the turning stress on it being a tandem?

Bill,

Cool hubs are oil filled, no grease.  They use 20W50.  What happens is, the seals don't hold up, and you sling oil everywhere.

I had a problem with inner seals on 4x4 axels years back with water getting thru I would use a water proof grease on the outside lip to keep it lubed it was too dry and would wearout. There is a moly additive for oils too. Just like doing front hubs on older cars rear wheel drives you had to lube the seals just a bit where they ride on the sealing edge with grease or if ran dry they would wearout too.  If you look at the seal there is a vee between the two seal lips you could put grease in that vee and the seal will keep wet and lubed and won't run dry and wearout.                      BigBill

Just use waterproof grease on the seal "Belray" makes some good stuff at your local motorcycle shop if you can't find it anywhere.
