Tex,
They're right, the rear trailing arm bushings (rear TAB's) probably are the only ones needing replacing, they start to go at about 100K and by 160K the clicking in the back end will become quite frequent during take off. It is not a bad idea to replace bushings before they make noise, in fact it is cheap insurance. The tool worked well for me and cost about $13 to make it myself. HOwever, if you live in the rust belt you WILL need air tools, and a good chance you will have to air chisel the old ones out like I did. look underneath at them and see if there is alot of rust on the bushings or the trailing arms. they are a press fit. air wrenches will make the job easier anyway.
also, spray PB blaster on the bushings for about 2 weeks before you do the job. If you are going to tackle this yourself it is a pain in the a$$ (PITA), but it can be done (took me 5 hours with air tools). there are plenty of lil tips from others who have done this, just ask when it's time. It may not be a bad idea to replace the rear shocks too, only a couple extra bolts...
