When you’re refreshing an older trailer or replacing a worn hub, this Dexter idler hub assembly takes the guesswork out. It’s made for 2,200-lb axles with BTR spindles and comes with everything needed to get rolling again—inner and outer bearings (L44649), matching races (L44610), grease seal #10-9, dust cap, wheel bolts, and lug nuts. The 5 on 4-1/2" bolt pattern fits wheels from 13" to 15", and each hub handles up to 1,100 lbs. With all key parts included, you can swap out the old hub in one clean step.
This hub uses the same L44649 bearing on both the inner and outer positions (1.063" inner diameter). That means no mix-ups during installation and an easy match for spindles that don’t taper. Everything seats evenly on the spindle surface for a secure fit that runs smooth mile after mile.
Dexter builds these hubs from strong cast iron so they hold up under routine towing loads and steady use. The rigid flange keeps your wheel true, and the 1/2" studs are ready for standard lug nuts without extra adapters. It’s a solid, dependable setup that’s built to last.
If a bearing failure catches you off guard or you’re restoring an older trailer, having a ready-to-install hub on hand saves time. Because this assembly includes the bearings, races, seal, cap, bolts, and nuts right in the box, you don’t have to chase down separate components. Just pack your grease, slide it on the spindle, torque it down, and you’re back on your way.
1. Count the lug holes
Look at the wheel hub or the back of the wheel and count how many lug holes there are(also called bolt holes).
Common configurations include: 4-lug, 5-lug, 6-lug and 8 lug
2a. For even lug counts (4-lug, 6-lug, 8-lug)
Measure from the center of one lug hole directly across to the center of the hole opposite it.
Common configurations: 4 on 4", 6 on 5.5", 8 on 6.5"
2b. For odd lug counts (5-lug)
Measure from the center of one lug hole to the outer edge of the hole directly across (not center-to-center since there's no directly opposite hole).
Common configurations: 5 on 4.5" (most popular), 5 on 5", 5 on 4.75", 5 on 5.5"

Thankfully I havent had to use the hub yet. I bought it as a spare, as changing a hub instead of changing seals on the side of the road may be a lifesaver. Thanks for the email follow up. I will be back to shop. Oh, my neighbor just bought a boat and I gave him your website link, with a strong recommendation.

I'm sorry you were disappointed in your experience with us. Dexter hubs are made in America, but the bearings they use are sourced from overseas. We do offer American made bearings, races, and seals that are Timken brand, but they are sold separately.
