1994 Plymouth Voyager Feels like suspension looseness and w

It wouldn't be the first time a nut wasn't retorqued after an alignment. Bearings will make a whine sound starting at 35 mph when they go bad, strut mounts will make a coffee percolator type noise going over bumps when bad. Was the ball joint checked?

Yes. Well, sort of. When I had new tires installed the mechanic on duty checked the front in suspension and said the ball joints look good. Now, I know how to check for a worn ball joint.

The inside at the bottom should be flush with the housing (or outside of it) when new. It is a little depressed but not dramatically.

I don't think the struts were ever changed in 15 or so years and the way it feels and acts it just seems likely to be the struts and strut bearing because everything else seems tight, I did check the tie rod nuts, etc. And they are set to 55 ft lbs.

There is no noise coming from anything that I have noticed. It's a little bumpy riding all the time and when I hit a bit of road that is bumpy or messed up (at around 45-50 mph), the left side shakes really bad ( I cannot really tell if it is a wobble from side to side or an up and down motion.

That's why I was thinking that perhaps the strut is coming apart and/or the strut bearing has gone out.

At over 200,000 miles, struts are a top of the list item, but to check the ball joint, jack the tire until it's off the ground high enough to place a bar under it, pull up and down on the bar, if the joint is worn you will see it moving up and down, also grab the tire at 3 and 9 o'clock positions and shake it, if it moves, replace the joint. If it is as you suspect, and the strut came apart, oil should be visible leaking from the top of the shaft and seal area. If you plan to keep it, replace the struts just on principal! Are the tires showing a scalloped edge? This is a sure sign of the tire bouncing while you drive, and is a bad strut.
