Mercedes-Benz GLK-Class Service Manual page 66

Fixed joints with finish-forged tracks are installed at
the wheel end. The deflection capability of the fixed
joints has been increased to 51.5° to give the vehicle
a very small turning circle.
Tripod sliding joints with finish-forged tracks are
installed at the front axle transmission end and
between the left front axle shaft / intermediate shaft.
The geometry of the tripod sliding joints has been opti-
mized to reduce the inner friction forces and thus
improve the vibration characteristics of the vehicle.
The left front axle shaft and the front axle transmission
are connected by an intermediate shaft, which is
passed through a tube cast in the engine oil pan. The
intermediate shaft is supported on the left side of the
engine oil pan with a roller bearing that is sealed on
both sides.

Front axle shafts and engine oil pan
Plug-in splines with snap ring locks allow the left front
axle shaft to be pushed onto the intermediate shaft
and the right front axle shaft to be inserted in the front
axle transmission.
The vehicle is equipped with a new engine oil pan with
a centrally positioned sump that has been standard-
ized for all engines. The modified sump system neces-
sitated the following new or modified components:
• Oil suction pipe
• Oil deflector
• Bracket for oil level switch
• Oil dipstick guide tube and oil dipstick
• Upper and lower section of oil pan
