My '12 TDV8 4.4 sits on 142000kms.Some of it on bad Africa roads.The RF is starting to sag overnight,not to bad yet but noticeable.

Tried a search but could find nothing referring to my model with the electronic shocks.Can one only replace the airspring as on normal shock models or must it be the complete unit?And this would obviously be much more expensive!!

Advice please!! 2012 TDV8 Vogue SE 4.4

I initially replaced just the air-springs in my MY12 when they were holed by mud containing coarse granite sand. I've since replaced the complete struts which had become quite useless after 2 recalibrations to extend their lives so have kept the removed air-springs for next time.

So it is possible to only do the air springs?What brand did you use for the airspring and for the complete unit?Complete unit from Billstein seems to be available here but quite pricy.See mention of Arnott here as well. 2012 TDV8 Vogue SE 4.4

I fitted BMI air-springs then more recently fitted Bilstein struts. The Bilstein struts are fitted with Dunlop air-springs of which I wasn't aware prior to getting them but if they don't last then the BMI will be refitted.

A rear air-spring has now succumbed to the granite sand so 2 Bilsteins are on their way. I'll have to put the rear on ramps at full height to hose the mud out of them as well as the fronts which I regularly clean at super-extended height.

Gee Graeme does seem that only us operating our RR's in the sticks replace air-springs  2012 TDV8 Vogue SE 4.4
