Question:

I have an old 4x8 trailer that has 1inch straight spindles on it and hubs that have an approximate inside diameter of 115/16 and 2inch across the middle. Not sure what I need and I do not have the old set that the trailer came with bearing kit

Expert Reply:

We do offer a couple of bearing kits that may work for the spindle on your 4x8 trailer. I recommend first confirming the spindle measurement with a digital caliper like # PTW80157 if you have not already. Even the slightest difference in measurement can determine the correct bearing kit.

For example, the TruRyde Bearing Kit # DL21792 is for a 1 inch BT8 spindle and uses L44643 inner and outer bearings.

However, the TruRyde Bearing Kit # BK1-150 is for a spindle measurement of 1.063 inches and has different L44649 outer and inner bearings.

I have also attached a helpful article on replacing bearing, races and seals for you to check out.
