HIGH OIL PRESSURE ALL OF A SUDDEN--

2000 Pontiac Bonneville

2000 Pontiac Bonneville 6 cyl Front Wheel Drive Automatic 115000 miles

our oil pressure all of a sudden went from like 60# to almost 120# do you know what would cause that?
Question #2----when it gets freezing out, the rear suspension gets still and one side sits and inch higher than the other, and when you hit a bump in the road the car feels like a lumber wagon, and like jolts or dashes or wobbles? From like the back right to the front left, like teters, and almost gives you whip lash and and a sore butt. Any ideas, or have you ever heard of this before on this model?
Thanks

Q1- Check the oil pressure with a mechanical gauge if it checks out-replace the oil pressure sending unit-if not normal consider replacing the oil pump.

Q2- Have the rear suspension checked out could be the struts/control arms.
