These rubber rings ensure that the grease stays where it belongs. If the rings are damaged, dehydrated or hardened, the pumped grease will leak out, which should be avoided.
As our Volkswagen Buses are already very old, there will not be a single Bus out there where these rings will still be reusable. When overhauling the kin g and link pin, you must replace them.
If you want to buy a complete overhaul kit (mentioned under the related parts tab), these rings are included.
