Question:
Can you tell me if this kit is compatible with Worthington 4x8 utility trailer gross weight 2K? Im unsure on spindle size: Trailer Idler Hub Assembly for 2,000-lb Axles - 5 on 4-1/2 - Galvanized Part Number: AKIHUB-545-2-G-1K

Expert Reply:
Hi Charles; we don't have a way of knowing what axle is on that trailer, even with the gross weight. The Trailer Idler Hub Assembly for 2,000-lb Axles # AKIHUB-545-2-G-1K fits a straight spindle with # L44643 (1.0" inner diameter) inner and outer bearings. Within that same axle rating, there are also straight spindles that use # L44649 (1.063" ID) inner and outer bearings like on the # AKIHUB-545-2-G-2K.
If you have a tag on the axle the serial number can be used to identify it through the manufacturer. If it is worn or missing, the only option is to pull the hubs and either look at the bearings for part numbers, or measure the spindle or ID of the existing bearings with a digital caliper.
What do you typically haul in the Worthington?
