Guys, those running Caltrac's on their street car, do that rattle/thump and bang during normal cruising??
The squeak is from the front eye bushings. Grease them once a year. I wish there were grease fittings. The rattles and banging is from the bolt on top of the spring. I had a piece of heater hose over the bolt for several years. It worked but wore out quickly. Now I have a 1/4" thick piece of polyurethane glued to the top of the spring. It is holding up much better than the heater hose.
Now if I could just silence my worn out strut rod bushings without tearing apart the whole front end i'd be happy. They make way more noise than the caltracs.
