    Default Quick Wheel Bearing Queston

    I lost the bearings on one of my trailer wheels due to a leaking seal. Setting for 1 1/2 year plus water did them in. I can't for the life of me read the numbers on them but here's the spindle diameters. Do any of you guys know the numbers I need or do we need more numbers?

    Spindle where the seal rides = 1.685"
    Spindle where the innner bearing rides = 1.375"
    Spindle where the outer bearing rides =1.063"

    The bearings and races are junk.


    Thanks guys for any help you can throw out there............john

    Here are the numbers from my spare bearings:
    outer race: L44610
    outer bearing: L44649
    inner race: L68110
    inner bearing: L68149
    Cant help with the seal as I dont have a spare on hand.
    I would seriously consider buying genuine Timken bearings from a bearing supply house. All the local trailer shops could supply were Chinese made stuff. Those are what I keep on hand for spares.

    Argh! This podunk town doesn't have anything but the Chinese stuff. It promised that it was a direct replacement but there is no way that the inner bearing race is going to go in there. Even stuck the race in the freezer for a bit as well has heated the hub with a propane torch. . Gonna have to regroup and see if I can find some real parts someplace else

    John, did they give you an L68110 race or an L68111? Both will fit the L68149 bearing but the outside diameter of the L68111 is larger(2.363") than the L68110(2.328"). Might also want to measure the I.D. of the hub.

    Grrrrr. You nailed it! They gave me a 111 vs a 110. Back to the joint to order the RIGHT bearing race! Thanks so much for all the help

    hey craig, i'm sure you know more about this than i do. i have the L68149 (1 3/8) inner bearings, but my inner races are L68111 that say "1 3/8 cups for 1 3/8 bearings". those are the last race's/bearings i installed, about 25000 miles go. i don't know what the difference would be between a 68110 and a 68111??? outters are the same.
    i've got chinese, mexican and american stuff in my hubs. and a ton of miles on this trailer, plus a lot of launch and retrievals. maybe something else would last longer, but i can't complain. this trailer has at least 80000 on it since i've owned it.

    Bob, I have no idea why there are races for that bearing in 2 different O.D.s, especially when the difference is so small. Perhaps just the choice of the various manufacturers of the hubs. I ran into the problem many years ago on my previous trailer, so kept the info when I replaced bearings on the current one.

    In my 30+ years in auto repair, I have never installed a wheel bearing or axle bearing that didn't come wrapped in protective wax paper (or a sealed plastic bag) inside a well labeled box . My local trailer supply has the bearings stored in 1/2 gallon tubs with no wrapping at all. I just could not bring myself to gamble on them. They were cheap enough to keep on hand as spares.......after all that pretty much guarantees I'll never need them, right?

    craig, i never say never.. all mine either come in plastic wrap or sealed plastic. i carry a box everywhere i go that has enough spare stuff to completely rebuild two entire hubs, including tools necessary and bearing packer. just don't like bein unprepared if i'm gonna go on a 3000 mile r/t. shouldn't have a problem, but...

    My trailer uses the same set up bob. And i will tell you the 68110 is thicker and will not drive into the hole. I thought i was nutts one day changing the races and i pounded the hell out of it till it finally cracked. Same inside just different outside.
