Vehicle in question is a 2000 Pajero/Montero (NOT Sport). Recently I noticed the outer edges of both my front tires have started to wear out more than usual. I took it into a suspension/steering specialist today, and was told my upper control arm bushings, upper and lower ball joints need replacing. The front tires do not sit 'flat' on the road, and only the outer sides have full contact with the road, wearing them out considerably.

Is there anything else worth replacing whilst these are being done? Apart from the shock absorbers, tie rod ends and pitman arm, everything else is 11 years old and has 310,000 kilometres/193,750 miles on them. I only want to do this once. Thanks!

 

It sounds like you got most of your bases covered...
I would inspect all of the stabilizer bushings for wear while you're "in there" and also examine all of the dust covers on the front end for cracks.

Remember when you're putting everything back together that the lower arm ball joint does not take grease.
It's also a good idea to only "snug" tighten the bushings when you have your rig up and fully tighten everything to specs. when the vehicle is back on the ground.

Good Luck,
Mr. Z.
