Just to let you know the weekend I did this. I powerflexed the bush on the engine and swapped the top mount for a new one. The bush on the engine was starting to crack and allow too much movement in the engine allowing for the driveshaft to actually catch the bottom wishbone bolts at the front.
So they have scored the new drive shaft I put in.
The power flex bush was £22.
However the old bush was a bugger to get out. I ended up chain drilling the bearing out.
Then used a big hammer and chislel.
Once the old bush is removed. Gave its quick sand down and popped a new bush in. The power flex one comes in two halves so very easy to fit. Plus a load of rubber grease.
All in all much better and should last the life of the car. I only powerflexed it though as it was cheaper than the OE bush from Alfa or even shop 4 parts.
