Volvo S90 D5 Polestar AWD

The Polestar optimisation increases engine torque, which means drive shafts and CV joints are subjected to higher mechanical loads during acceleration. It is therefore particularly important to fit high-quality parts engineered to handle this power.

The most common symptoms are vibrations through the bodywork under acceleration or unusual noises while driving. On AWD models, an unbalanced propeller shaft can produce similar symptoms, so a thorough inspection is recommended.

It is often possible to replace just the outer CV joint if the rest of the shaft is undamaged. However, if there is wear in the inner joints or severe corrosion on the shaft, replacing the complete drive shaft is usually more cost-effective and dependable.

Vibrations from the propeller shaft are typically felt through the vehicle's floor and seats rather than the steering wheel. They also tend to vary with road speed rather than engine revs.

It requires solid mechanical knowledge and the correct tools, including a torque wrench and equipment to release the wheel hub. For an experienced DIY mechanic it is entirely feasible, but adhering to the correct tightening torques is essential.
