          Hi Greg
          The cradle mount is what you call the sub frame. There is a front and rear one. I got all my bushes through Martynf at VAGPARTS. The wishbone bushes were powerflex, gearbox, diff and engine mounts are standard. Car no longer has vibrations

                is there a rubber mount for each side of the gearbox, it doesnt show that there is in the diagram but i'd presume it was a mirror image?

                Thanks,

                  David,

                  yes there are, the diagram only shows one side for some reason, I'll take that pic of one soon.

                    Here you go David, you can just about see where the rubber of the mount has split.

                      something I will have to change on mine I think, how much are the rubbers? How difficult is it to change them?

                        The snub mount is located at the front of the engine. If you open the bonnet and look down towards the intercooler, you can probably just see a bit of it.... It's held in place with a sort of 'n' shaped bracket of which you'll see the top of with the bonnet open....

Not sure it's really doing the car that much good to be honest but i am going to change the gearbox mounts and the centre prop bearing too as all that stuff is 12years old now so hopefully it will cure it. In the meantime I am thinking of bolting on a new OEM version of the rear diff mount to get rid of the 'noise' coming through the car
                          Cheers

                          I also get this exact same symptom since putting in the Powerflex rear diff mount, and actually it's bloody awful. The longer I've had it, the more I hate it - it makes the car really unrefined when you're pottering about - it's a vibration phase at 1500rpm and in my car its so bad that it makes my CDs skip. I'm seriously considering changing back to a normal rubber one.

                          Also like the other posters here, installing the new rear diff mount didnt' actually get rid of all of the transmission shunt. When I first installed it, I convinced myself it made a difference, but recently I was driving another car for a few days, then went back to the S2 and noticed just how bad the shunt really is.
                          Awful.

                          I suppose on a 14 year old car all the rubber bushes are going to be in some state of knackeredness, but for anyone that thinks the Powerflex bush diff mount is the panacea to solving transmission shunt, it certainly isn't, and it actually makes other aspects of car vibration worse.

                            Never "felt" these syptoms myself but had a similar feeling in an old '80 sport, are you sure it is not gearbox/engine mounts???

                            Not that much help I know!

                              Well, all I know is that when you come off throttle in, say, 2nd gear, you get a definite shunt. The theory was that the rear diff mount would solve it, and to be fair, the rubber mount was completely shot, so if there are other mounting points, I'm sure they're equally destroyed. At least the rear diff one was easy to get to, but it hasn't cured 100% of hte problem.

                              I just don't think that these polyurathane bushes are the Mac Daddy having lived with one on the rear diff for 9 months - it really has increased the low-rev vibrations of the drivetrain quite significantly.

                                I reckon you should adjust your snub mount first. Make sure the bracket is resting on the bush itself. This cured all of my driveline shunt at the time. Although I now have a minor clonk from the rear diff but I can't hear it myself....Doug told me he could hear it when he was in the back recently.
