how long should it take to change 2 outer tie rods and 2 lower control arms?

The tie rod ends about 1.3 hours to 1.5 allowing time there for wheel alignment. Labor guide says 4.8 hours to replace both control arms (seems high but that is what he guide says).

Well i think that a skilled tech would take about 2 hours at the most. It could take some one in there drive way on jacks and stands days depending on there skill level
