I Rear Suspension
This repair group covers removal and replacement of E39
rear suspension components. A general description of sus-
pension systems and ride height specifications can be found
in 300 Suspension, Steering and Brakes - General.
CAUTIOI\C
Some E39 models are equipped with aluminum suspen-
sion components. The following cautions apply:
Due to the chemical and corrosion characteristics of
aluminum, do not bring into contact with battery acid.
- Do not clean with wire brushes with brass or iron bris-
tles. Only use brushes with stainless steel bristles.
Do not expose to flying
sparl~s from grinding/cutting op-
erations.
* Do not subject to steel welding splashes.
0 Do not expose to temperatures over 80°C (176°F).
even for shortperlods. Temperatures in painting facili-
ties are not a problem.
Special tools
Special service tools are required for some of the work de-
scribed in this repair group. Most of these tools are special-
ized press jigs and pullers that might be replaced by standard
pullers of various sizes.
Read the procedures through before beginning any job.
