The sway bar or as it is more commonly called the anti-roll bar or stabilizer bar is vital in controlling the sideways rolling of the body of the vehicle during cornering; the bar itself rarely fails, but the links and bushings are prone to wear. Proper mounting of the bar is very important for it to work and various diameters can affect the roll characteristics of the vehicle. Worn bushings should be replaced to return cornering performance. For the removal and installation, the process varies between the model series. For the 240 Series the vehicle must be raised and supported, the wheels removed and the splash guard taken off before removing the sway bar from the struts and links. The bushings should be examined and replaced as required. Installation includes reconnecting the links, setting the bar, and tightening the nuts to given measurements. The 700 Series, 940, and 1992-94 960 models need to be done in similar steps; raising the vehicle, removing the splash guard, attaching new bushings, and then securing the sway bar. The 1995-98 960/S90/V90 models are a case of connecting the sway bar to the axle beam and support arms with new nuts and bolts and including proper torque specifications. For the 850, C70, S70 and V70 Series, support rails are required to lift the engine then remove the underengine splash guard and steering gear connections so the sway bar can be removed and refitted with new nuts and correct torque settings.
