Garter spring - Hub seal


Recommended Posts


Its a 1985 110. Axle number 21S38523B. The inner seal has instruction embossed onto the seal indicating it should be seated at a depth of 4mm. Couldn't find anything on the outer bearing seal so I assume it fitted flush, with the gaiter spring on the inside, and that the spacer would seat the seal at the appropriate depth... am I on the right track?

The spacer that the seal runs on is compressed by the bearing nut as you no doubt know. The level of the lip is critical in that it contacts the edge of the spacer to effect the seal. The seal won't abrade on anything, as the drive flange is too far away from it for this to happen I think. Some people leave the outer seal off so that axle oil lubricates the bearing instead of packed grease doing it.

Les. :)
