Control arm bushings for Nubira

[Jamus]

Brought in my 2000 Nubira wagon cdx to dealer for inside tire wear(front),hoped it was an alignment issue.It is in a way,turns out the bushings on both sides for the control arms are worn out.Dealer says 300.00$ plus tax(canadian).He says 25.00$ for each bushing(100$).So that means 3-4hrs labour?His shop time is 55.00$/hr.How big of a job is this?Thanks.
