Although rear suspension components such as torsion bars, trailing arms and anti-roll bar can be removed independently of the rear axle assembly, it is recommended that you have some special tools to successfully complete this job.
Due to the complexity of this procedure and the need to use special tools to accurately set the suspension geometry during installation, the operations of removing and installing individual elements of the rear suspension are beyond the competence of an amateur mechanic and should be entrusted to a Peugeot / Citroen dealer.
The procedures for removing and installing the rear shock absorbers and the entire rear suspension assembly are described respectively in paragraphs 14 and 15.
