Replacement Trailer Hubs Using L68149 and L44649 Bearings  

Thanks for providing all of the information for your axle. This axle is going to use the standard 3,500 lb axle bearing sizing. You can use the Bearing Kit #BK2-100, which will come with bearings, races, seals, cotter pin and tang washer - everything…

A true 1 inch spindle is a BT8 spindle, like #TRU94FR. The next closest one would be the BTR spindle which is commonly referred to as a 1-1/16 inch spindle, like #TRU44FR and is more common than the BT8. Both of these are typically used with 2,000 lb…

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

If you know the trailer axle capacity that's a pretty good way to determine what spindle you have. Or if you get me the bearing numbers. You can also measure the spindle where the bearings ride and with that info I can let you know what you…

As long as the seal in the bearing kit part #BK1-150 is flush with the hub it is okay to have a small gap between the seal and inner bearing. When installing the seal you only insert it enough so that it is flush with the hub. The seal's job is…

The pilot diameter on a wheel, like the one with part #AM30620, is the diameter of the bigger hole that is directly in the middle of the wheel. The pilot hole diameter of the wheel for the part I just measured is 2.84". I have attached a picture…

I'd go on the tighter side of what you mentioned where there's no play yet you can still spin the wheel several times on one push. You might put your hand on the hub to feel if it's getting overly warm next trip you take but I believe…

After you've packed the bearings and assembled everything, carefully slide the hub assembly onto the spindle and install the outer bearing. Install the spindle and tang washer and run the spindle nut down finger tight, then rotate the hub back…

The hub you have like part #84545BX uses the bearing kit part #BK2-100 for replacement bearings/seal/races. I attached a review video for this bearing kit for you to check out as well.

Polyurea is in the wheel bearing grease and is compatible with marine bearing grease but not the Red grease. Red grease is compatible with marine grease but not standard. I attached a help article that has a chart with all of the grease…

The difference between the single lip and double lip seals is that the double lip grease seal will have two rubber lips that are in contact with the spindle. The double lip grease seals are usually used in marine applications to give a better seal…

I have attached a chart you can check out that describes the torque needed per wheel size, wheel stud size and material. For an 8-inch wheel with a 1/2-inch wheel stud the torque is 75 to 86 ft-lbs. For a 15 inch steel wheel with 1/2 inch wheel studs…
