As a follow up to JDstr4A's posting for his TR-4. I have my 3 apart and need to re-do the tubes and cable to wipers. Motor has been rebuilt. Any suggestions on how to clean the tubes and cables (cable turns but is very stiff) and then what lubricant and how in the world do you get the lubricant onto cables and thoroughly distributed in the tubes? I am 75% complete on a frame off. Plus do I put lubricant into the motor assembly?
