The air suspension hanger brackets can be bolted
to the frame if required.
To reduce the torsional stress on the vehicle
frame, the air suspension hanger brackets must
be reinforced according to the forces that will be
applied (see drawing C-04.00.501516).

R Reemmaarrkkss::

The trailing arms, air bags and plastic piping should
be protected against sparks and weld splashes dur-
ing all welding work. The earth terminal must under
no circumstances be attached to the trailing arm or
hub.
It is not permitted to heat the air suspension hang-
er brackets for alignment work.
