A howling hypoid rear axle, a slipping clutch or knocking propshaft joints are the classic symptoms once the miles have piled up on a PV or Duett. Power runs from the engine through the gearbox and propshaft out to the rear axle, and every link in that chain has its own wear points – from the release bearing to the crown wheel and pinion.

We're here for you and your Volvo
The parts are grouped by function, so you land in the right place whether the job is in the driveline or the rear suspension:
The PV 444, PV 544 and Duett 445/210 were built with two different rear axles, ENV and Spicer, and the parts are not interchangeable. Check which axle your car has before ordering – compare with the pictures in John's tips at the top of the page.
The axles differ in the shape of the axle housing and differential cover. Compare your car with the pictures in John's tips at the top of the page, or contact us with your chassis number and we'll help.
The clutch plate, pressure plate and release bearing are normally replaced together. Check the master and slave cylinders and the flywheel face at the same time so you don't have to do the job twice.
Early 444s and 445s with the B4B and B16 have a three-speed box, while the 544 and 210 with the B18 got the four-speed M40. The parts differ, so start from engine and model year.
Fast delivery from Hökerum, 1-year warranty and a 90-day right of return.
