1989 560SEC, Rear vibration over 60mph.

In hopes of not throwing expensive parts at a problem, over 60mph the rear end of my car starts to vibrate.

I have verified that the rear stabilizer link set needs to be replaced. Could the vibration in rear over 60mph be the bad stabilizer link set?

Also, the boot closest to the differential is torn on the axle assembly (driver’s side) and needs to be replaced. What do you think that means? Could the torn boot be a clue that the axle assembly is out? What would a bad driver's side axle assembly feel like at 55mph?

85 300SD w/ Trap Oxidizer vacuum presure reading

I followed Kent's instructions the best I could in his Vacuum Diagnostic manual. Here is what I did and what readings I got: following the main black plastic line to the firewall, there are several lines that split off. 5 in total, I believe. I unplugged the four smaller, colored lines and plugged them with golf tees. The remaining line is actually some sort of plastic housing unit with a curved rubber hose attached. I took my measurements from this point and with the engine on, I got a measurement of 10 psi from my mityvac. I think this means something is up with my vacuum pump, unless I performed my measurements incorrectly.
