Volvo V40 seats are comfortable and long lasting, but they may need to be replaced from time to time. The front cloth seats are secured to the floor of the Volvo by a runner and rail system. The rear cloth seats are secured to the floor and rear of the V40 with retaining bolts. The front seats are the hardest to remove because of the interlocking nature of the runner and rail system, while the rear bench seat is the heaviest because it is just one long, bulky seat.
Open the driver side door and look under the driver side seat. Locate the plastic cap on the front of each seat rail. Use a Phillips head screwdriver to remove the screw in the middle of the cap. Remove each plastic cap by hand once the screw is out. Pull the seat forward until the runners disengage from the rails. Pull the seat up and out of the V40. Slide the replacement seat into the rails and back until it hits the stops at the rear of the rails. Fasten the caps back into place on the front of the rails. Repeat this process for the passenger side front seat.
Open the rear driver side door and fold down both of the rear seats by reaching behind the seats and pulling the latch that secures them upright. Fold the seats down flat and locate the hinges at the rear of each seat. Use a Phillips head screwdriver to unscrew the seat backs from the hinges. There will be a screw in the centre of each hinge, and a hinge at each lower corner. Pull the seat backs up and out.
Unbolt the lower part of the rear seats from the floor of the V40. There are struts coming down from the seats to a rail on either side. Unlike the front, these are stationary rails; they do not move forward or back. Remove the three bolts on each rail, one at the front, centre and rear. Pull the seat bottom up and out.
Bolt in the new rear cloth V40 seats. Line up the bolt holes in the rails with the holes in the floor of the V40. Slide the bolts through by hand first in all the holes. Then tighten the bolts down until the seat no longer wiggles when pushed on. Fold the seat backs on the new seats up until they are locked in a vertical position.
