What causes a drivetrain shuddering above 25 mph while holding the gas pedal steady not accelerating or slowing on a 1986 Lincoln Town Car also with a rear vibration when cornering sharply under 10mph?

could be a great number of things in the drive chain. i would start with the transmission. it can make the car shudder feeling like you just ran off the pavement onto the notches in road to make the driver aware he's no longer on the pavement. to cure this, have your tranny backflushed at a lube shop which generally cost about $75. the torque converter and fluid is the culprit that causes this annoying vibration...WARNING!!! make sure the proper transmission fluid is used, this is what caused the problem! good luck Thanks for the answer...it turns out that the problem was two shot universal joints and an occassional minor engine misfire that lead to the shuddering. There is still a minor vibration toward the rear and I will certainly look into your solution to see if it fixes that vibration. Otherwise I'll start looking at the differential as this issue seems to be concentrated in the rear axle area as oppossed to the transmission (could just be a manifestation of wishful thinking though, can't afford a new transmission). Thanks again.

How do you identify what the vibration is from the drivetrain in 1992 Nissan Serena?
Most commonly when you feel a vibration in the floor board , or seat the source is usually the tires are out of balance. If you notice a vibration while accelerating, but none when coasting , there's an indication it may be in the driveshaft or drivetrain. If the vibration is noticed more frequently in the dash or rear view mirror, the problem may extend beyond the tires and into suspension components. Check tires for abnormal wear or cupping which may give you an indication, alignment factors also come into play.

Will bearing hub replacement cause steering vibration?
A bad wheel hub searing can cause vibration on your steering. Loose or broken steering and suspension components can cause vibrations when accelerating, decelerating or changes in speed. Worn tie rod bushings, damaged struts or shocks are common causes of vibration. Drivetrain problems, such as a bad wheel bearing, damaged CV-joint (front-wheel-drive cars), a bent or imbalanced driveshaft (rear-wheel-drive cars) or missing chassis/drivetrain damper weights are all examples of speed-sensitive vibrations.
