suspension diagnosis isn't easily described in a step by step receipe format.... since there are many parts that interplay (some with more critical roles than others in daily use)

their engineering, & performance interplay must be understood prior, the test drive characteristics/ observations/ conditions noted, specs reviewed, visuals on worn items noted, and.....I've seen on occasion a big lever bar used to test flex points and bushing conditions closer

its best to sit on the shoulder of a compent tech and have him/her explain their inspection process and reasoning for the resulting report card....suspension items do wear over time
