How to Powerflex a V70/S60 wishbone

[myshed]

Bushes on my 2004 v70 D5 (160k miles) are shot - mot advisory 2 years running, now tramlining badly, and front tyres paying the price (they were useless anyway, needed replacement, so not unduly worried that they were "wasted"). So, having just replaced tyres, bushes are immediate next. Have followed this (and other) threads, and did think of replacing both front and rear bushes on each arm, so all advice here being assimilated. Doing a bit of web browsing (as you do) for Powerflex bushes, and these popped up.

The cost difference is not great, so the temptation is to go for replacement arms with bushes already fitted.

Any opinions?

btw - cannot see many of the pics, especially the photobucket ones - am I missing something?

Thanks
