Hey All,

Just recovered from a fuel pressure regulator diaphragm failure (badly flooded engine as you can imagine) and I had the left front corner of the 91 Sovereign jacked up for a couple of days while I checked to make sure that the charcoal canister had not been filled with liquid fuel and drained the liquid out of the vacuum line to the purge valve. When I got the new regulator and vapor canister re-installed and let the car down, it started and purred like the contented kitty that it has always been, but now the shifter is very stiff and I hear a drive shaft vibration which starts at about 30 mph, peaks at about 40 and then quiets down a bit between 40 and 60 and then starts getting louder again. All I can figure is that something moved while I had the LF corner up in the air and stayed moved after I let it back down. I put the whole car up on stands and wiggled under it to check the drive line alignment and to shake things around a bit, but could see nor feel anything obvious. I have an appointment on Monday next to put it up on the lift at my local shop to see if we can find anything wobbly with the wheels turning (not quite brave/stupid enough to do that on a set of stands with components spinning within millimeters of my head). Any thoughts would be greatly appreciated.
