I previously powerflexed my upper wishbones (worn out bushes)... and my swing am bushes all LOOKED absolutely great nic, so I decided to leave them... I even sold on the bushes at some loss to Mitch.
Now, upon re-assembly, the (outer) swing arm bushes are knocking like crazy!!! Never did that before! So I guess the stress of taking it apart and re-assembling has broken their form and now they need replacing. Amazing how 1mm of play can cause such a noise.
So in hindsight, should have spent the time powerflexing everything... it's just a pain to get the old ones out... Still, no bother to do just do the pair of outer ones... £25... I am enjoying doing it in (many, many) stages and will continue like this.
