BTDT many years ago on an '87 5K, replacing the inner rear bushings only.
Clunks and excessive rear tire wear because of rear end misalignment is
likely the TZ arm bushings. These bushings are/were expensive, stealer only
parts, so inspect them carefully before deciding to remove the arm and
replace. Could be something else. As with all rubber bushings, don't
tighten the thru bolt until the suspension is in its loaded static position.
The other common rear suspension problem is dry and squeeking ball joints on
the upper transverse links. While you're in there these should be checked
for looseness and if still tight can be relubed by injecting oil with a hypo
needle throught the rubber boot.

Just an arbor press and an assortment of pusher and back up sleeves.
