Recommended Replacement Spindle for a 1963 Small Boat Trailer

Question

Question:

Hi, A couple of days ago i asked about my boat trailer grease seals were leaking badly. After taking it apart i seen that the spot that the grease seal rubs on is ruff. Probably wore out the seal. Please see picture. Do you carry an axle sleeve repair kit? The trailer is a 1965 small boat trailer. Outer bearing # 44643 - 1 inch inner diameter. Inner bearing # 44643 - 1 inch inner diameter. Seal inside diameter is 1.25 Seal outside diameters are 1.983 inches thank you

Unfortunately, no we do not carry axe sleeve repair kits, so your options would be to replace the entire axle, the spindle, or you can just use the Spindle Grease Seal Set for L44643 Inner Bearing and 1.980 Bearing Buddy # BB60001.

This kit is designed to fix the exact issue you're having by providing a new surface for the grease seal to ride on which would be the same as using a new spindle but would be significantly cheaper and easier to do.

We have the Bearing Buddy Bearing Protectors #BB1968SS that fit a hub bore of 1.968 which is likely the size you have. The measurement may be slightly off based on the outside temperature as steel can expand and contract based on temperature.

Yes, a 5.30 x 12 tire will fit the same rim as a 4.80 x 12 tire. Both tire sizes fit on a 4 inch wide rim. There are a couple of things to consider when changing tire sizes. First, the larger 5.30 will be approximately 1.4 inches taller than the 4.80…

All of the 12 inch wheels with 4 on 4 bolt pattern that we carry have a pilot hole that is 2.8 inches or greater. If the wheel bolts have a 60 degree cone (like #RG02-020 as an example) then the bolts will be able to center the wheel on a hub-centric…
