C5 suspension lubrication
Short of using a needle to inject lube into each rubber boot, is there any way to lube the chassis joints? I had a terrible squeek on the drivers side rear suspension. I raised the car, loosened the bolt for the lower a arm? and sprayed silicone lubricant , then re tightened the bolt. Squeek is gone but I would like to lubricate all other fittings. Thanks

Sorry I can help with the chassis joint lube issue, but I have a suggestion for you to try to get rid of some squeaks. On my C5Z, I had a creaky-squeaky noise when the suspension traveled. It was coming from both the front and the rear, so it ruled out a U-joint issue (I don't have an AWD Z06!). It was worse when it was hot, and it was driving me insane! I hit the forum and scoured through a bunch of really great ideas. The one I settled on was that my anti roll bar bushings were to blame. I used spray silicone and hit the bushings really well - squeak was gone! If you haven't tried this yet, they're really easy to reach. Good luck.

I had a nasty squeak for a long time. I think I fixed it with a new tie rod end and new swabyars complete with new end links and bushings. it was a nice upgrade at the same time. I haven't heard a sound in a few weeks, but prior to that I did still hear it a couple of times. just in case this comes back and I need some new way to try to fight it...

I'll have to look up a diagram, but the bolt I loosened is at the upper A arm suspension, it has a rubber bushing and when I sprayed the silicone lube in it, it seemed to quiet the squeek. I sprayed every piece of rubber I saw at the time. The poster prior to yours also added some good info that I will look at next time I put the car up. Thanks for the reply

I've had several C5 s and I have found that most times the creaking/squeaking comes from the swaybar bushings. Just loosen the swaybar bolts and lube the rubber grommets... hope this helps
