ELIMINATING PROPELLER SHAFT
VIBRATION AND NOISE
Vibration or Noise:
Requirements:
Propeller shaft in perfect optical condition.
Balance propeller shaft, if balance plates are missing and propeller shaft is
suspected to have imbalance (refer to instructions supplied with the balancing
machine):
Important!
The wheel suspension of the driven wheels must be supported when trial running on a
jacked up car (deflection angles of output shaft).
The maximum speed of the car in jacked up state and on rollers must never be
exceeded.
Conform with safety regulations!

Aligning Propeller Shaft:
Center propeller shaft, using Special Tool 26 1 020 if necessary.

Checking Deflection Angles of Joints and Correcting If Necessary:
Apply Special Tool 26 1 030 (gage) on the oil sump flange and measure angle of
engine.
Note:
When correcting a deflection angle by installing shims, remember that the deflection
angle of the adjacent joints will also change.

If Oil Pan Flange is Not Accessible:
Apply Special Tool 26 1 030 with an auxillary rail (steel ruller) and measure angle
of engine inclination.
Note:
When correcting a deflection angle by installing shims, remember that the
deflection angle of the adjacent joints will also change.

Apply gage on propeller shaft front section and measure angle.
Measure deflection angle* of joint disc and, if necessary, correct it with shims (up to
max. 3 mm or 0.118") on the transmission suspension or center mount.
Example:

Engine angle	2° 16´
Propeller shaft angle	- 2° 06´
Joint disc deflection angle	0° 10´

* See Specifications

Apply gage on propeller shaft rear section and measure angle.
Measure deflection angle* of center mount and, if necessary, correct it with shims (up
to max. 3 mm or 0.118") on the transmission suspension or center mount.


* See Specifications

Apply gage on final drive with help of a rail (steel ruler) and measure angle.
Determine deflection angle* of universal joint and, if necessary, correct on center
mount by installing shims (up to max 3 mm or 0.118").


* See Specifications

Hard Movement on Side:
Note:
The propeller shaft was balanced in assembled state and must not be turned in
the slide.
Mark an unmarked propeller shaft with a punch.

Remove threaded sleeve (1), wsher (2) and rubber ring (3).
Check rubber ring, replacing if necessary.
Disconnect propeller shaft on slide.
Clean and lubricate keyway with Molykote Longterm 2**.
Assemble propeller shaft that the punch marks are aligned.


** Source: HWB

Note:
Propeller shaft sections are mounted in such a manner that universal joints are
in one plane.
If the slide had been disassembled by mistake without punch marking, ir will only
mean the possibility of installing the propeller shaft wrong by 180° because of
balancing.

After Finishing Installation:
Tighten threaded sleeve with Special Tool 26 1 040.
Tightening torque*
