brother u r sitting in karachi, the biggest market for spare parts in Paksitan just go to sher shah market and replace ur suspension with a kabli one...the kabli suspension is perfect one.....don go for new....and also they u wud be compensated in case u return ur old suspension to them...
moreovber regarrding the rattling of ur door glasses...just go to some electriciana nd tell him to open your door trims and check out the door machines....as they might have developed play in them...he might greece them or do the needful for u...
