Got some kind of leak

[HAULIN IT]

That is the spring from around the inside lip of the seal. It makes a bit of pressure so the rubber stays against the yoke. The new seal will have one on it. Pack the backside groove where the spring is with wheel bearing grease or Vaseline so the spring doesn't come off while your installing the seal. Lorne

The black high-temp RTV silicone sealant sold at any auto parts store,even wal-mart will do just fine for your repair.

I went ahead and used the high temp RTV silicon. The parts store guy was like "I never use this..." but the old one had it when it came off. So I'm using it.

you dont have to use the sealer. you will see it just dont slide in place you have to tap on it just right, and dont bend it

Turns out its the other thing. That weird automatic speedometer adjuster for different tire sizes. Now I got the same part leaking on two different vehicles lol. Guess those O rings just finally get old.

That Springie tihing goes inside the lip of the  output shaft seal.

Wow this topic got old fast guess i havent been here longer than I thought.

Does anyone know where they sell new seals for the speedometer compensator/adapter/whatever its called? The thing that the speedo cable plugs into. I've been looking around for a while now, and I can't seem to come up with anywhere that actually sells new little rubber seals. Or even a whole new unit.
