Yeah from my reading threads I find it unlikely it's the ARB bushings also, but I guess I have to go with my mechanic on this,
If the ARB's are worn then I guess they need changed anyway.
Trial & error game.
I know what you're saying, but my way of thinking is, if you buy new bushes and that's not the problem, is the mechanic gonna refund you for them and not charge you labour since he hasn't done @*!# to fix the problem?
Yeah you are 100% right, but I tried to diagnose the problem with no joy, it's been bugging me for months now.
I would take it somewhere else, not because he hasn't a clue, he may be right after all, but just to see if another mechanic diagnoses the same thing or at least the same area.
New drop links aren't that expensive and are very easy to change yourself with a few basic tools and a jack. Even if that isn't the problem, you can check them very easily before you buy replacements, or if you're planning on keeping the car for a while I'm pretty sure they'll need done at some point anyway, so it's not wasted money.
For me, it's just such a coincidence that he diagnosed an area of very common failure, but the wrong part, so I'd be going for the common known issue first.
