Default Squeak, Squeak

...... just crossing over 105K miles now. I'm hearing small amounts of squeaks here and there coming from under carriage. I already replaced the rear lower control arm bushings (replaced the whole arm both sides) because of my OCD nature. This time the noises are different. Nothing wrong with the way the car drives. It's just me noticing these things but no one in my neighborhood hears it except me. My hearing is better than dogs, so to speak. My neighbor and I swap cars a lot (he has MDX hybrid) and that car makes even more noises.... so it doesn't bother him.

Most probably one of the rubber mounts on the axles ( subframe) or some sort of suspension bushings........

Which rubber part goes south first, typically? I'm going crazy here. Help.

I would visit a suspension shop and let them diagnose which joint has play. You need special lift [not just the hoist] and long levers to test each joint.

Some squeaks can be cured by lubing too. But then which joint?

Could be the sway bar bushings.

Could be anything. Evidence should lead to the culprit.

I have seen front struts or strut bearings cause a squeak. Can you trace down which end is making the noise. Perhaps by going over a speed bump?
