I’ve been helping a friend bring back from the dead a ‘67 Bug he bought about a year and a half ago. Yesterday we installed a rebuilt Rancho transaxle that he bought through Chirco. The transaxle comes totally dry, obviously. When we top it off with the 80/90 hypoid gear oil; what is the procedure to break it in? I’ve read you need to change the gear oil after the first 300 miles and then every 30,000 but how exactly do you first put it into service? Just take it off the stands, start it, put it in reverse, back up from the garage and drive it down the street? I want to be careful because, like I said, the thing looked totally dry inside; want to make sure we do this properly. I know many of you have done this but funnily enough no one mentions these first few moments in a rebuilt transaxle’s life. Thank you in advance for your help.
