Salm dear it must be tirade or steel balls etc Axcel they worn out with time on rough roads and need replacement after 4 5 yeaers. I would suggest if your keeping this car for few years than always spend money to purchase original parts expensive but they you will be happy with ur car
Try to purchase do this work with original parts by Suzuki workshop in your city. show it to them they will tell u cost of every thing need to be changed ................. good thing is if there is any issue you can complaint on them and can reparit your car again even if parts used by them are not good u can replace again and again until your issue completely resolved
if you want to do it by local mechanic than purchase original parts from market like Pindi sadar or any other city where suzuki original parts available dnt use chaina or thiwan or malaysia parts they only work for few months
third option is to purchase original used parts from kabari bazar but there is issue they can be good or can be bad as they are already used parts
my suggestion spent 5 to 10 thousand in suzuki work shop in Pindi or Islambad and make ur car like new.
GOOD LUCK
