Service Technical Information 142/17 ENU 4271 4 Noise Symptom - Creaking From Rear End Area: Checking rear spring strut for damage (SY 142/17) Model Line: 911 Carrera/S/4/4S/GTS (991) 911/S/4/4S/GTS Cabriolet (991) 911 Targa 4/4S/GTS (991) 911 Turbo/S Coupe/Cabriolet (991) Model Year: As of 2017 up to 2018 Subject: Rear supporting mount Symptom: Creaking noise from chassis area at the rear of the vehicle. Cause: The spring force of the coil spring may be outside of the tolerance range. The increased transverse force as a result of this can overload the insert in the supporting mount. The piston rod may no longer be guided in centrally and touches against the supporting mount housing. This produces the metallic noise. Remedial Action: Before doing any other work, the following components must be checked for damage: • • • • Coil spring, shock absorber, supporting mount and insert. If the piston rod has already caused damage, the inserts, supporting mounts and coil springs at the rear must be replaced in pairs. The shock absorbers may or may not need to be replaced, depending on the mileage. Work Procedure: 1 2 Disassemble the affected rear spring strut.
