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.
