REPLACING SEALS
The hub or rotor must be removed from the axle and the seal forced out. It is
impossible to remove the seal without damaging it. So, when you remove it, plan
on replacing it. Because seals are a high quality design not widely available, you
will have to obtain a replacement from the dealer, a bearing supply company, the
trailer manufacturer or Unique Functional Products. Seals installed at the factory
may have a Hypalon coating on the outside diameter. If you replace seals
without Hypalon apply a thin film of Permatex High-Temp RTV Silicone Gasket
Maker on the seal outside diameter and hub bore prior to installation.
