If Total overhaul (i mean front and rear shocks springs kamani setup etc) then :-
The cost is different for Qabuli parts and new parts. With Qabli (used refurbished parts) both front and rear suspension will cost you around 10-20k (including labor depending on your bargain skills from car used parts market in your vicinity). Whereas new parts cost depends on which quality parts you will use however on average total of changing complete front and rear suspension may cost you 30k-50k (budget totally depends on quality of new parts installed.. for Mehran you'll get 3 to 4 quality category different priced parts).
