Land Cruiser suspension clunk, is this just worn bushings?

[carlbrooks]

My Land Cruiser has developed a clunk from the front end when I go over bumps or turn into driveways, and it's been getting more noticeable over the past couple of months. The car has done about 180k so I'm expecting some wear, but I want to know if this is a simple bushing job or if it's something more involved like the control arms or the shocks. I've read that these trucks are pretty robust but the front suspension components do wear out eventually. A neighbour suggested a professional Toyota repair garage in Musaffah Shabiya and said they've been solid for his Hilux, but I'd like to hear from other Land Cruiser owners before I commit. My question is whether the clunk is usually just the sway bar links and bushings, and how much of the front end should be replaced at this mileage. Also, is it worth doing the whole suspension refresh at once or just the worn parts? I'd rather do it properly than chase noises one by one.
