"The Trouble With Trunnions" ...is feeding them!
And I've finally devised a simple (and cheap) way to force feed them their regular 5,000 mile dose of Cod liver oil ;-) ...or AMSOIL [or name your favorite] 90W gear oil.
Using a small "oral syringe" - no needle, just a plastic nib. I got mine (1 teaspoon) for free at the local pharmacy.
Put a rag under the trunnion to catch the extra fluid, so it doesn't run down the sidewall of the tire (if on). On the eclat/elite, it's easy to do with road wheel on, just turn the steering full lock and get to work...
Siphon up a teaspoon of gear oil, uncap the trunnion, put the nib into the hole and jam the front end tight against the trunnion, squeeze *quickly* and watch...
You should see some nasty old juice slip out from under the rubber top seal. Keep shooting until you do.
If you have trouble getting a pressure seal, slip a neoprene flat washer over the nib -- small enough to seal around the hole, big enough not to go in.
Remember to cap the hole again. Tada!!!
There was me thinking you had problems with your drivetrain!
