I have looked at several vendor sites and cannot find any replacement seals for the rear axle pivot. These are a rubber washer 1 7/8 dia. 3/16 thick with a 1 inch hole. There are four of them. I have also looked through McMasterCarr; no luck there either.

Steel rubber has them for $30 for the set. Seems a little high for 4 washers. Close sizes, but not the right size, at McMaster Carr are less than $10 for 5 washers.

Does anyone know who might have these?
