i recently got bushes and shocks replaced at 2 seperate times, so im guessing it would have been cheaper if i did it all at once, but anyways
Shock/Spring installation
Remove old suspension, place new suspension = $200
Labour for Camber (front/rear) bushes, castor bushes, power steering rack bushes, subframe bushes + removal of steering rack & fit a supplied one = $300
+ wheel alignment = $100
So basically I paid around the $600 for labour BUT thats including removal/fit of power steering rack, so it would be cheaper if that was not done.
Hope that helps
