I have a Toyota Matrix 2005, and am installing a new a/c compressor(came without oil). Does anyone know how much oil the a/c compressor will hold?

My 4 runner is making a noise when going over bumps, sounds like an old car that needs greasing. I was told by Toyota dealer it needs struts and shocks and tires.
I am a woman and drive mostly highway miles, can't understand why it would have this problem, not even paid off.

How often do water pumps goes bad or do you have to change them frequently. Thank you so much

the clutch to the a/c turns on and off causing it to blow warm and cold air.

replaced the front pads twice & the rotors once i get a harder shimmy at about 1/2 brake pedal and worse the higher the speed. hard brake or light brake they feel almost perfect I do have a high spot blueing on the rotor not sure if it's the calipars hanging (4 piston type) or maybe the rubber brake hoses? those are the only other things i can think of causing the problem. I have no problems stopping no pulling just the annoying shimmimg at normal braking the pads look evenly worn just the rotors have a 2" blue/high spot on both the originals and the new replacement rotors. I am stumped but don't want to buy new calipars on a hunch just yet without a 2nd opinion, thanks
