It has macpherson struts in the front and torsion springs at the rear.
as the rear is torsion it is not straight forward. the torsion bars have to be removed one side at a time, with the torsion bar out simply adjust hub the required amount and replace torsion bar. then do the other side. this can be hard as the bars can be difficult to remove. best left to professional should cost between £60-£100
Front is torsion bar and rear is leaf spring. Both front and rear have anti-sway bars http://en.wikipedia.org/wiki/RPO_ZR2
The 1964 GMC does not use torsion bars, in 4x4 applications it uses a leaf spring in the front. The 2wd uses coil springs. Both models use leaf springs in the rear, the Chevy version used what is called a truck arm suspension with coils in the rear.
Try the Haynes Manual.
A Vauxhall Vectra rear suspension diagram is available through their service manual. Online Vectra service manuals are also available to be purchased through several websites.
In the manual, look in library
The Peugeot 306 has a conventional Mcpherson strut front end with coil springs over shocks. The rear end is a solid axle with torsion bars that run across the car linking both arms. There are no rear coil spings.
Revised leaf springs in the rear. Revised torsion bars and torsion bar cams (a.k.a. 'pork chops') in the front
A lot they are completely differant.They have went from leafspring to a four link rear suspension. the fronts are simmalar but they went with a coilover instead of torsion bars
you can turn the torsion bar up it will give you 1 in to 2 in you can bye the rear shackle kit at auto zone for 20.00 $
Yes , shock absorbers front and rear. 4X4 models or models with the 4X4 suspension (but aren't real 4X4 models) will have rear shocks only and then have torsion bars in the front.
