Metallic creak at the rear from the rear shock absorber top mount

Engine / equipment

911 (991) Carrera, Targa and Turbo

Period mentioned

2017–2018

Symptoms

A metallic creak around the top of the rear wheel when going over speed bumps or potholes.

Possible cause described

The rear coil spring force may be out of tolerance; the side load overloads the insert in the shock absorber top mount and the piston rod rubs against the mount housing. Porsche describes it in technical information 142/17 (February 2018): if there is already damage, the rear inserts, top mounts and coil springs are replaced in pairs, and the shock absorbers depending on mileage.

Check for the garage

Note when it creaks (speed bumps, potholes, turning). At the garage, have them remove and inspect the rear spring and shock absorber assembly (insert, top mount, spring and shock absorber) before looking at other parts.
