Parts Needed For Adding 7-1/4 Brakes To Trailer With 2,000LB Axle


what is the difference on 7x1.25 drums 5 on 4.5 pattern between L44649 bearings and L44643 and how to tell which is needed when adding 7x1.25 brake to my trailer?


Expert Reply:

The Easy Grease Trailer Hub and Drum Assembly for 2K Axles # AKHD-545-2-EZ-1K includes the 1" inner diameter Bearings # L44643. The Assembly # AKHD-545-2-EZ-2K includes the 1-1/16" inner diameter Bearings # L44649. To determine which ones will fit your axle you will need to remove the grease cap and spindle nut to find the number on the outer bearing. If there is not one of the bearing numbers stamped on your bearing you will need to measure the spindle using a Digital Caliper # PTW80157.

You will also need the Electric Trailer Brake Kit # AKEBRK-2 which includes both the left and right brake assemblies.

For the Electrical you will need a Hopkins 7-Way RV Style Connector w/ Molded Cable # HM20087, etrailer Trailer Wiring Junction Box # 3430001-JBK, Bright Way Trailer Breakaway Kit # 3802337 and Brake Wire # 12-2-1. The brake wire is sold per foot.
