1998 Volvo S90 Problems

Air Pump Check Valve Failure

The Check Engine Light may illuminate due to a failure of the air pump check valve.

Worn Sway Bar Bushings Causing Knocking From Front End

The sway bar bushings commonly wear out, causing a knocking noise from the front of the vehicle. Replacing the worn bushings should correct this concern.

Vibration from rear brake rotors are common

Vibration problems from the rear brake rotors are common and require replacement of the pads and rotors, and the installation of special shims. The symptoms often occur when the brakes are used heavily from repeated braking, braking from high speeds, and braking while going downhill. The entire vehicle can vibrate and shudder, like it is being driven over train tracks.
