I'm Awesome
Today i was able to free up, clean, and lube up all 8 of the headlight adjustors. Also sandblasted the headlight buckets and bulb retainers. Got the headlight bulbs in my cart at rock auto. May buy them today.
Cleaning the adjustors was a bit of a pain and took several hours. I used an aluminum etch acid called alumiprep 33 to clean the brass on the adjustors along with a brass wire brush to polish them up and a rinse. I soaked them in hot soapy water , and blew em out with compressed air. Then with the headlight bucket linear jack screws removed i kept spraying them with LPS-2 penetrating oil, and worked the gear adjustor parts both directions with a 1/4" socket and an air drill until they freed up to where they would turn easily. Then i rinsed em out with laquer thinner, and using a syringe, i packed them with Aeroshell 22 synthetic grease.
Honestly i didnt think they were going to free up from the get go and work as smoothly as they do. Its a testament to GMs design work on these. Using brass for the linear screw jack adjustors and the adjustor screw end with the gear, these things still work after all these years after cleaning them up.
