Without PAS (not available in UK, or perhaps at all anymore)
These ones have the pivot point moved further forward to reduce the castor to 1 degree, and have one notch on the front side of the rubber below the sphere. All the others are 3 degrees castor and have two notches at the front...
With PAS, without Hydractive
With PAS and hydractive
These have the obvious differences of pipe size, but also the taper for the cylinder shaft is different, as is the size of the middle nut.
With PAS, Hydractive and ES9J4 engine (V6 I think?)
Yeah most likely. The V6 model is VERY heavy at the front, perhaps they just used more rubber in the mounting to reduce fatigue with the extra weight.
Hmm, I wonder if my car now has the V6 version fitted.... as they are definately different to the original ones on Dad's Xantia.....a lot more solid and substantial rubber block on the under side...
Note that there are two types of cylinder boot listed, before and after RP 7245, but it appears that all the new tops require the new cylinder boot - which gives credence to the story that the tops were modified.
Mine must now have the new type cylinder boot fitted as well - its quite a bit longer with probably 30% more ripples in the concertina, and is a lot softer material. (Neoprene instead of plastic ?)
The original ones really struggle to reach with the suspension right up, especially when they get a bit old and hard, and the rubber ring at the top deforms, then they fall down and let the dirt and muck in... my new ones still have plenty of flex when fully extended, and yet they don't bunch up when its right down.... definately an improved design.
The new strut top rubbers also seem to have a much more pronounced circular lip for the boot to attach to, perhaps thats why a new version of the boot is needed to match them...
