Having also fitted a new 'Dog Bone' I agree with Timmus regarding the above post. It has transformed my 2001 A2 1.4 TDi which had a bucking action both on power take up but particularly on decceleration. It had a pronounced 'knocking' with passers by turning to look. It is now a different car.
As I have the original Dog Bone with its failed rubber mount at the subframe end it should be able to be rebuilt when a suitable replacement mounting becomes available.. I spoke to Powerflex last week to ask if they have a mount and understand that they are currently looking at making one available and to watch their website. All enquiries to them about the A2 torque tube (dogbone) can only help to bring forward this availability and possibly sooner. Either a separate mount to install DIY or available on exchange. The small bush on mine remains intact after 12 years and over 120K miles. My transmission remains worn but is now a lesser issue.
