Rattling is like Kir Kir Kir better explained in urdu (کڑ کڑ کڑ) on roads with multiple small bumps, My mechanic says "اسٹیرنگ بج رھا ہے" because the axil is not fitting completely in it"s place due to longer distance between the gearbox & where it fits in the wheel, & it will eventually break down. Much worry for me, My neighbor got Corolla springs installed only in rear wheels, the car no longer hits speed breakers, but every time he brings his car out of the basement parking the front bumper strikes the ramp, Gosh!
