Hi Nipper
I think I have enough to go on with identifying the clunking noise, the bush that tcspeer suggested certainly looks to be shot given the amount of grease around it, the one on the right hand side is fine, I am currently looking for a supplier that will deliver via DHL to the Falklands, that is usually the hardest part of sourcing parts.
I was interested in the date of manufacture to make sure I got the right part number when asking for pricing. The option of returning wrong parts is an expense in itself that I would rather not have to do.
Tyres are all the same brand and are regularly rotated to equalize wear, so i don't think that is contributing to the problem, like you say age is probabaly the cause, although wear and tear here is harder on most vehicles, given that 90% of the roads are unsurfaced, and one of my more frequent trips is 70 odd miles all unsurfaced and some off road to my folks farm.
The Falklands probably have one of the highest ratios of Land Rovers to people in the world for the reasons above, I just like to be a little different.
Thanks
