Just saying as you have said that you have had them on and off a few times - they can come undone which will result in the strut & steering knuckle (basically everything, the whole lot) moving under braking - I'm speaking from experience

Powerflex bushes are yellow & purple - they will be the right ones (and the best) if I remember correctly they also have the pf number stamped on them?
The 'other' poly bush manufacturers are just shite, simple.
