Tie rod and ball joint in indica is really cost effective( i wouldn't say cheap as it sounds cheap). The struts earlier when i owned them costed around 1450 for Gabriel ones. Not sure now. arm bush was again not that costlier. rear suspension set up should come around 4.5k i would say total cost of 14,000 is worth it. A bit expensive though.
Thanks for updating. Glad the car has been sold by an enthusiast to an enthusiast. Those who wish to discuss technical issues related to Indica, please feel free to use the following thread: Tata Indica: Technical Issues & Solutions.
