What Type of Grease Seal Keeps Out Water the Best

Updated 08/03/2020 | Published 07/30/2020

Question:

I have been fighting water penetrating my axle seals. I believe the spindles are worn and allowing the water to enter. Trying things in lieu of replacing the axles last resort. do you thing the oil seal on the spindle might be more forgiving? they look much wider than what an axle seal may provide. Thanks. I have the 3500# axles with a #84 spindle.

Are you using double lip grease seals or single lip seals? Is there a metal spring that runs around the seal to hold it tight to the spindle? I'd verify that first but if it's not that it's either a bad spindle or you are using the wrong size seal. Oil seals aren't typically better at keeping water out than grease. Normally both do a great job.

I attached a picture that has a diagram that shows the different seal styles.

I also attached a link to a page that has all of the grease seals we offer as well.
