Product Description


Volvo (TSB) Techinical Service Bulletin: VCC-130664 US 2003-03-20 / S80-2-21-0030

"A knocking noise that may occur when driving at low speeds on uneven road or at sharp turns, can be caused by one of the the rear subframe bushings moving in the sub-frame. The knocking can sometimes also be felt in the floorboard under the drivers feet. Install an O-ring between the sub-frame and the bodywork on the rear bushings on both left and right side as a service solution."

This bulletin specifies this fix for S80 models but since the subframes and bushings are the same on other P2 models, it is likely that S60, V70 and possibly XC90 models may experience the knocking effect also.

Knocking noises are more commonly a result of worn out sway bar end links.

About Genuine Volvo

Everything IPD supplies under the "Genuine Volvo" designation are the factory original Volvo parts. These are the same quality parts that you will get in the blue Volvo branded box from a dealership. All Volvo supplied Genuine Volvo parts are made to specifications by Volvo and under their strict quality control guidelines.

Volvo relies on high-quality OEM manufactures such as Lemforder, Behr, Sachs, Bosch, Valeo, Siemens, VDO, Corteco, and many more to maintain its dedication to quality and safety.

IPD is the exclusive North American distributor for Genuine Classic Volvo parts outside of the Volvo Dealership network. We are proud of our Volvo heritage dating back to 1963, a reputation that is unmatched by others in the industry.

Many may not know this but Volvo in Latin roughly translates to "to roll".  The company was founded back in 1927 by Assar Gabrielsson and Gustaf Larsson as a spin-off from ball-bearing manufacturer SKF.  While the Volvo logo looks like the biology symbol for male, it's really the Swedish symbol for Iron. With a nod to its heritage in alloys, Volvo chose a logo that depicted a ring bisecting at one o’clock. Today Volvo is known around the world as one of the most iconic brands known for safety, longevity, and its enthusiast following.
