Hatts off to the Pakistani mechanics,they cant even bolt simple things like hand brakes,and end up screwing every possible thing that they can touch.BTW dear,do check the radiator cap or similar leak you just cant believe they sometime remove things off your car as well...
I serviced my car's front wheels and no surprises next day i was getting some more sounds from wheels... God knows what they have TAT (tighten up) in them.
Really if you keep car long enough you end up understanding your car better them these so called lethargic and careless mechanics.
Im sure they must have over tighten something there.
