you should stop driving this vehichle until it is fixed or resolved. You most likely are experiancing the arm support rusting out on the passanger side of car. Very common for these vehichles. It is getting ready to break. This is why it sqeaks. it is moveing. If this breaks while you are driving 30 - 45 - 55 or at any speed. You have NO control and are going to crash into whatever is in your way. I would seriously stop driving it. This happened to me, I was fortunate I was doing 5 mph while turning off highway. I was able to weld it all back up, and is a daily driver. Dont chance it, get it fixed.
