Well to finish my install, as advised by RS3Dell I needed to swap out my 034 dogbone mount for a Powerflex insert. With the Gearbox mount insert and the 034 the NVH was pretty bad
.
Firstly removed the 034:
And unlike most others it’s not bent:
Comparison of the 034 & Powerflex showing how much extra the Powerflex fills the voids:
Next push the insert into the bush. Only possible by using a jack I found as it’s a very tight fit. Use a flat surface on the jack such as a wooden block to avoid damaging the insert. Oh and if you’re going to do this leave the old bolt done up in the bush whilst pushing the insert in. This took me 2 attempts as with the bolt out the jacking must have moved the dogbone arm as the bolt wouldn’t re-engage in the top bush. With the old bolt left in whilst you fit the insert you avoid any issues:
Finally fit the 2 washers in the insert kit with a new bolt torqued up to 100Nm +90 degrees:
Final result is perfect. Barely noticeable NVH and clean, smooth gear changes
