The only way to know for sure is to check your bearings. That being said, the most common 4-bolt configuration is a 4 on 4 bolt pattern, which are typically found on 2,000 lb to 2,700 lb trailer axles. The only 4 on 4 bolt pattern hub and drum assemblies we carry are for 2,200 lb axles and use # L44649 inner/outer bearings. See below.

Compatible with 7 inch x 1-1/4 inch electric and hydraulic brakes
# 8-173-16UC3 - Includes bearings, races, grease seal, standard grease cap and lug nuts.
# 8-173-16UC3-EZ - Includes bearings, races, grease seal, E-Z Lube grease cap and lug nuts.

Compatible with 7 inch x 1-3/4 inch hydraulic brakes
# 8-276-5UC3 - Includes bearings, races, grease seal, standard grease cap and lug nuts.
# 8-276-5 - Includes races. Bearings, grease seal, grease cap and lug nuts sold separately.

You can either look for the bearing number stamped on the bearing itself, or use a caliper like # PTW80157 to measure the diameter of the spindle where the bearings ride. A spindle that uses L44649 will measure 1.06 inches.

I've attached a couple helpful articles for you to check out at the bottom of the page as well.

The Dexter 69-46 axle has a straight spindle with #L44649 bearings. For a replacement spindle you can use the BTR E-Z Lube Spindle for 2,000-lb Trailer Axles #TRU44FR. Then for an idler hub, the Easy Grease Trailer Idler Hub Assembly for 2K Axles…

I have exactly what you need to add a 7-way trailer connector to a 2016 Honda Odyssey. For this, you'll need to start with a 4-way trailer connector and I recommend the T-One Vehicle Wiring Harness part #118521 which is plug-n-play. Then you can…

The parts needed and steps taken to install a brake controller, like the Tekonsha Prodigy P3 #90195, on your 2016 Honda Odyssey will really depend on what they are wiring for your 7-Way. If they have wired all of the functions then you will simply…

Answer 10

Leaf springs are indeed supposed to flex and will flatten out some when under load. This reduces the distance from the top of the axle to the underside of the trailer above it. There isn't a specific distance this has to be but if the trailer is…

Answer 11

Double eye leaf springs like the part #e84SR do not have a front or back designation. Slipper springs like the part #e29SR do have a front and back.
