    Upper: when the bushings or balljoint goes bad.
    Lower: all the bushings and the balljoint can be replaced separately, but its not much more to replace the whole arm.

    You may notice clunking noises and/or check for play when the tire is off the ground.

    I don't think that all of the LCA bushings are replaceable. Meaning I don't think that every bushing on the LCA has an aftermarket part out as of now
