Rpm dips

Good evening.

Two things.

Is it normal for rpms to dip below 500 causing a slight shudder? If not, what causes that?

Second. Why is it that when I drive in the rain my car creaks and groans... Most notable if I drive over a bump... Like a speed bump?

Thanks all

Remove the black covering on the top of the strut mount(left pic), visible on the strut towers when you open the hood.
Squeeze lithium grease into the ball bearings

I had same problem few month ago, new mounts from 2009, added grease and now perfect

It does it with the back as well... If there access to a point in the back that can be greased?
