After almost getting stabbed in the back with a falling bonnet due to my gas struts seeming to have given up the ghost over winter ... (they are almost 15 years old) .. I thought ... arghh.. I'll get them seen to on the next service, as I don't want to some how unbolt the struts whilst trying to prop up the bonnet etc...
Then good old Aston1936 popped up on a feed .... and low and behold... the struts are only attached via ball clips ... so if you are gentle with a screw driver (ie put protective cloth around the area so you don't scratch your car if you slip), it took me literally under 5 minutes per strut to change ... and that was me farting around comparing the compression require push the old/new struts.
The bonnet was held up with a tripod stand ala 1936, but otherwise a 2nd pair of hands would be useful if you could borrow them for under 10 minutes (you could do it in 5mins if you concentrated).
Struts were AM originals from HWM - £31.45 each inc VAT.
I think quotes from workshops, were around the £130 - £170 mark to do the job.
