Workin on my buddies '91 Suburban that has a vibration at 35 mph. Does it in neutral and in 2nd, 3rd, and 4th gear. Doesn't matter what you do, but at 35 it tries to rattle your teeth out. The tires have been balanced on numerous occasions and seem to come out perfect.
I am thinking it is the center support bearing, but is there any way to test one of those? I grabbed the driveshaft and it moves around a bit. How much play should one of these have?
