Why does my 2001 grand marquis squeak in the front?

Here's the cylinder locations for your vehicle.

On a 2001 Mercury Grand Marquis :
firewall
4 - 8
3 - 7
2 - 6
1 - 5
front of vehicle

wheel hub need to be cleaned

Remove the appearance cover. Looking from the front of the car towards the windshield it is in the back left section in front of the wall, has a connector and two vacuum lines.

2003 marquis have rack and pinnon no inner tie rods

sounds like worn out shocks or struts

the number # 6 spark plug on your car is the second from the front on the drivers side of your car, or as your standing in front of you car looking into the engine compartment it would be the second from the front on your right. hope this helps

That sound is a sign of rusted parts. You need to get the front end checked and may as well get an alignment. The manufactuers have reduced the number of grease fittings for years.

All the car makers, not just Mercury claim the parts are lubed for life. The parts would last longer if they could get fresh grease, but most people blow out the rubber boots by overfilling them anyway.

If the alignment shop doesn't find a problem with your car about all you can do is use a light oil or spray Lithium grease into the squeeking part.

Yes. Squeal is from a/c compressor. Belt too loose.

I have to ask, does it do it when moving or sitting still, or both?

duse the howl go away when you trun a conner ?if it duse its a wheel bearn. as for the squeak its hard to pin point. try finding some one how duse mud run they would be ableto help you with the howl noise. have a nice day
