Locating Replacement Grease Seal for Harbor Freight Trailer with 1.21 Inch Inner Diameter  


Im looking for a replacement grease seal for a Harbor Freight Long Chih 4x8 folding trailer. The rubber part of the original seal has the number SDA 579 VB2 31 52 7 5. I measure the dimensions as follows: O.D. - 2.05, I.D. - 1.21 spindle surface, W - 0.27 inches.


Expert Reply:

The closest grease seal we have available to the dimensions you provided is the TruRyde # 34823. This particular seal has an inner diameter of 1.249 inches and an outer diameter of 1.983 inches. I was not able to cross-reference the number you found on the seal to an available part.

I simply recommend verifying the measurements you took on your seal with a digital caliper. You can also take a quick measurement on the spindle where the seal rides to get the inner diameter you need.
