Hi all,
I am hoping the knowledable people out there can help me out with a mysterious noise that has arrived in my car. I am hoping to sound somewhat informed before I take it to the mechanic and they tell me to just add oil.
The other day my car started making a ka-thunk noise when I come to a stop. This noise seems to be coming from somewhere on the passenger side. The dreaded ka-thunk happens at the first 3-4 stops I make after my car has been sitting for a long time (overnight). The car is also making a strange whirring noise or maybe a metal on metal noise when I get the car going above 25mph. Any help pointing me in the right direction is greatly appreciated.
The thunking noise MAY be associated with some part of the suspension, perhaps a worn or broken mounting bolt. There isn’t anything rolling around in the back or under the seats? In the spare tire compartment?
The metal noise could be a heat shield spinning on it’s last mounting bolt. Who knows? A close inspection while moving/thumping things may make it show up.
To begin without sounding critical since I am a total amature (sp?), always begin your discussion with a description of the year, make and model as well as the milage of your vehicle.
I would offer the following:
-
Possible motor mount (rubber mass) which connects the engine to the chassy.
-
Possible CV joint and its boot. You can check this out easily by looking inside the wheel.
-
There could be other things such as a harmonic balancer but this noise usually starts when you first start the engine.
Hope this helps…GGR
