Set up your trailer the simple way with idler hubs and an 80 inch spring center that matches your hanger spacing. If your spacing is different, spring seats can be re-welded to fit, and moving to a higher-rated axle may also require wheels that match the new hub bolt pattern.
They can make lubrication easier than repacking bearings. Verify your spindles are compatible with easy-grease hubs. After installation, add grease and recheck for smooth hub rotation. During assembly, protect spindle threads; if nicked, carefully dress them so the nut starts cleanly.
Yes, but check a few things first. Match your hub-face length and confirm the 80 Inch spring seat spacing. A 5,200 lb axle typically uses a 6 on 5-1/2 bolt pattern; 3,500 lb wheels with 5 on 4-1/2 won't fit the larger spindles. Plan on new U-bolts if the heavier axle uses a 3" tube.
It depends on the kit. Check that bearings, races, seals, washers, and castle nuts are included so you're not stuck mid-install. If they aren't listed, add them separately. Confirm the bearing sizes match your spindles before assembly.
Yes, if your trailer's spring seats measure 80 Inch center to center and the hub-face length matches your current axle. Measure your hub face to hub face and confirm it against the new axle. If your trailer uses a different spring center (like 82 Inch), have the spring seats re-welded to match. Verify the hub bolt pattern matches your wheels before ordering.
