U-joint is worn it will cause vibration with almost
any vehicle speed/engine torque condition. DSY—Drive Shaft and Yokes: Vehicle speed sen­
sitive, mechanical/audible vibration. The condition
will not cause vibration below 35 mph (56 km/h). Ex­
cessive runout, unbalance or dents and bends in the shaft will cause the vibration. Identify the actual
cause and repair/replace as necessary.
WB—Wheel Bearings: Vehicle speed sensitive,
mechanical/audible vibration. Loose wheel bearings
cause shimmy-like vibration at 35 mph (56 km/h)
and above. Worn bearings will also produce a growl
noise at low vehicle speed and a whine noise at high
vehicle speed. The wheel bearings must be adjusted
or replaced, as applicable.
AN—Axle Noise: Engine torque/vehicle speed sen­
sitive, mechanical/audible vibration. The axle will
not cause mechanical vibration unless the axle shaft
is bent. Worn or damaged axle pinion shaft or differ­
ential gears and bearings will cause noise. Replace
the defective component(s) as necessary.
SSC—Suspension and Steering Components:
Vehicle speed sensitive, mechanical vibration. Worn
suspension/steering components can cause mechani­ cal vibration at speeds above 20 mph (32 km/h).
Identify and repair or replace the defective compo­
nent
(s).

EA—Engine Driven Accessories: Engine speed
sensitive, mechanical/audible vibration. Vibration
can be caused by loose or broken A/C compressor, PS
pump, water pump, generator or brackets, etc. Usu­ ally more noticeable when the transmission is shifted
into the NEUTRAL position and the engine speed (rpm) increased. Inspect the engine driven accesso­
ries in the engine compartment. Repair/replace as
necessary.
ADB—Accessory Drive Belts: Engine speed sen­
sitive, audible vibration. Worn drive belts can cause
a vibration that produces either a droning, fluttering
or rumbling noise. Inspect the drive belt(s) and tight­
en/replace as necessary.
DEM—Damaged Engine or Transmission Sup­
port Mounts: Engine speed sensitive, mechanical/ audible vibration. If a support mount is worn, noise
or vibration will occur. Inspect the support mounts and repair/replace as necessary.
ES—Exhaust System: Engine speed sensitive, me­
chanical/audible vibration. If loose exhaust compo­
nents contact the vehicle body they will cause noise
and vibration. Inspect the exhaust system for loose,
broken and mis-aligned components and repair/re­ place as necessary.
