Beemon Posted June 28, 2018 Share Posted June 28, 2018 Have you greased your front suspension? 1 Link to comment Share on other sites More sharing options...
D Yaros Posted June 28, 2018 Share Posted June 28, 2018 It could be body mounts, bumper bolts, ball joints, center link, A-arn; a whole slew of possibilities. Link to comment Share on other sites More sharing options...
Fr. Buick Posted June 29, 2018 Share Posted June 29, 2018 There are a whole lot of suspension points to lube... Then get under the car with sockets and wrenches and tighten anything you see. Link to comment Share on other sites More sharing options...
56 Buick Posted June 29, 2018 Share Posted June 29, 2018 Was the squeak there before you changed the coils? If it wasn't then that makes me think it's the coils or shocks. Perhaps start a process of elimination by spraying parts of the coils / shocks with silicone spray. If you spray a particular part and then the squeak stops then you have your culprit. Then you just got to figure out why it's squeaking ... Link to comment Share on other sites More sharing options...
packick Posted June 29, 2018 Share Posted June 29, 2018 I assume you put pads on the top and bottom of the coil springs? If not the springs will squeak. Been there, done that. Link to comment Share on other sites More sharing options...
NTX5467 Posted June 30, 2018 Share Posted June 30, 2018 IF the squeak is a "rubber squeak", then the affected rubber bushings can be dry and need some rubber lube on them. Might be the body mounts, too, as mentioned. For rubber-based squeaks, the best thing I've found is dielectric silicone paste like you'd put on the inside of spark plug boots so they'd pull off the plug easily. It's available at most auto supply stores in a small tube. I used it on the rear hood bumpers on my '77 Camaro and a pressure car wash usually would NOT wash it off. Doesn't degrade rubber, either. BUT is has to be between the rubber bushing/bumper and what it contacts. There's also the old RuGlide liquid rubber lube from ages ago, which can still be found.
