U-Joint shaft question...

[EddiePetty]

What is the purpose of the two o-rings mounted on the forward end of the U-joint shaft (Pcs. 15 of http://mercstuff.com/fichea.htm ) other than to eliminate metal-to-metal contact with the gimble bearing and reduce noise? I see no way that it acts as a grease seal.

Ayuh,... The Bearing would never turn at All without 'em....

If any bearing Race isn't locked to whatever it's protecting, it Can't/ Won't/ Don't work....
