Double Lip Grease Seal for a 3,500 lbs Boat Trailer with About 1.67" Spindle Measurement
Updated 07/10/2019 | Published 07/09/2019 >
Question:
HI, I have an EZ loader tandem axle boat trailer. i paid someone to replace the bearings and i think they used the wrong seals. after only two times in the water i started to burn up bearings. i think the axles are EZ loaders own axles they are torsion axles probably 3500 or 3700 lb. axles. The spindles all have a speedi sleeve on the seal shoulder and the shoulder diameter with the sleeve removed is 1.655inch the sleeve thickness is about .015inch measuring at an undamaged area. the seals that were installed are a 442251 single lip seal. the seal barely contacts the sleeve and does not contact the spindle at all when the sleeve is removed. i am trying to find the correct seals for these axles but the part store guys arent much help without a vin or part number to go by. i would like to use double lip seals if possible preferably with a garter spring on the primary lip. can you possibly help me with this problem. Thank you

Helpful Expert Reply:
It definitely sounds like you have the wrong seals, especially if they are barely making contact. I believe the seal you are looking for is part # 168255TB which is a double lip seal with the spring on the primary lip typically used for 3,700 lb marine hubs. It has an inner diameter of 1.687" and an outer diameter of 2.561". You need to measure both where it rides on the spindle as well as where it sits on your hub to ensure that it fits properly.
If you have a different measurement than 2.561" for where the seal sits in your hub please let me know and I can see if we have something else that works for your application.
