Any lube that would stop front suspension squeaking?

It is possible that you have polyurethane bushings.25 years ago I did my Duster with polyurethane bushings. No one told me that you had to grease them.My squeak was from the sway bar bushings.A few years later some suspension companies started installing grease fittings in their parts.
I know what you are talking about. Man did they squeak ! Places like Energy Suspension or PST has grease you can buy.
In a pinch you can also use teflon Marine Grease that won't wash off.

You sound like you’ve experienced the same thing. The squeaking is almost embarrasing - I’m assuming some of this can be heard outside the car. It seems to be coming from many sources and past efforts with spray lubricant have had very little effect.

If the squeak was due to poly bushings that haven't been lubricated the spray lubricant would have at least temporarily eliminated/reduced the squeaking. The fact that the spray lubricants didn't at least temporarily solve the issue means either the source didn't get sprayed, or lubrication isn't going to fix it.

If nothing is worn out, I'd just live with the squeak, or, turn the radio up louder! :lol:

If it squeaks though it means it is worn out, or soon will be. If they're rubber bushings the squeak means they're garbage already. If they're poly bushings and they've been squeaking for awhile, well, they're probably worn out now because they need to remain lubricated and the squeak means they dried out. If they're run like that, the friction makes short work of them.
