my $0.02, if one of your LBJs was messed-up, replace both. one simply can't know without careful examination. as you correctly state, an LBJ failure can result in catastrophe. i like to replace all paired components in pairs. i realize that's more expense than everyone can manage all the time, but generally it produces more predictable behavior, not only with alignments, for instance, but also the wear tends to progress evenly and thus in a few years (?) when it's time to replace again, you don't have to remember which one is the most recent or whatever.

agreed. while poly bushings *are* firmer than fresh rubber, they do compress. if they didn't, we wouldn't be using them as bushings. those ears take a *lot* of abuse, and if they were to flex and crack due to poly bushings alone, we'd be seeing trashed rigs and recalls due to the most minor bumps. old rubber gets *really* hard, harder than fresh poly bushings. i just cannot get on board with a claim like that.

if the swaybar doesn't bear vehicle weight, what weight does it bear? whoever told you that is stepping onto a narrowly defined slippery slope there. if it doesn't bear vehicle weight, then it serves no purpose other than bearing its own weight. if your source means it bears no *static* weight, yep, 100% correct. if suspension parts are only those that bear weight with the vehicle at rest, on perfectly level pavement, then lots of components aren't suspension components -- rear control arms and panhard bar for instance. you can take those all off and the vehicle doesn't collapse on the garage floor.
