Yar long ago, in 2009 i guess, the cost of ONE OEM control arm was 9000rs. by now, it should be atleast 12k or more. offcourse, nothing would be better then OEM stuff but u gotta have the bills justified. i cant spend that much every 2nd year (i mean there are other parts requiring change too) because of the high mileage.
its always recommended to get the complete suspension overhaul done at once (not bit by bit like i did). because, u must ve heard the famous saying "A chain is only as strong as the weakest link" if ur control arms and assembly is new but shock absorbers are old, they ll put extra strain on the new parts too, hence reducing their life. so, do discuss it with me before u get the work done.
n yes, i get all the parts from that niazi auto guys. someday when we meet again, i ll tell u an old, interesting story about him on the dinner table
