Any lube that would stop front suspension squeaking?

I agree 100% with diagnosing the problem and finding out exactly where the noise is coming from. It is completely true that rubber begins to deteriorate from day 1 when it's made, just like the inertia ring in a harmonic damper. When I worked at O'Reilly, nearly every single one we ordered in for someone had cracks in the inertia ring from sitting on the shelf for so long. Of course, being crappy made chinkesium didn't help any. Much the same with most front end parts, unfortunately.

Here's what I would do if this was my car. I would get the car up on ramps so the weight will still be on the wheels and it will still squeak. Get you a long 3/8" drive extension and use it as a stethoscope going around at the different pivot points as someone jounces the suspension. All the control arm bushings, strut rod bushings, sway bar bushings if it has one, put it in each ball joint. Even put it on the tie rod ends. Just anywhere any pivoting action takes place. The strut rods don't really pivot, but do them anyway. Trust me. When you get to the offender, you WILL know it. Good luck and keep us posted.
