[s-cars] Vibration under load suspect center support bearing

[RGuzz]

94 S-4, 92k miles...thought the problem was resolved after replacing 
tranny mounts but still present somewhat and now have bucket-o-bolts 
sound while decelerating under load. Center support bearing now the 
prime suspect. CVJ's appear "tight" with shaft on the car. Have a lead 
on a replacement shaft from a kindly lister. Everything else is tight on 
the car. I'll surmise the undue torque on the shaft from the flattened 
tranny mounts may have accelerated the center bearings demise...
But this bearing can be replaced? Anyone know the part numbers and how 
easy is this to do? I did one on my 2002tii about 20 years ago...If
I remember.
Great advice thus far,
Rich
