Question about 2000 Mercury Grand Marquis

3 Answers

I recently replaced my tires and shocks on my 2000 Mercury, Grand Marquis. When driving down the road the car tends to not hold the road very good when hitting a bump in the road. The car only has 71000 miles on it and the front end seems to be tight. Cound it be weak coil springs?

Did you fit the correct shocks? Did you fit them the correct way up? Did you prime them before fitting?

Your fault points to a definite shocks problem first and it's extremely unlikely to be weak springs. The next most likely candidate are one or more suspension bushings.

I had the same thing happen to my 03 Marquis. Got brand new expensive, highly recommended tires, and it seemed to not hit the bumps in the road very well, so I got a 4 wheel (not 2 wheel) alignment and that did the trick. It takes about an hour and a half was only $87 and worth every penny. They put it up on a computerized rack which tells them how to make the adjustments and it worked, like driving on air compared to before. But, take it in to your favorite auto repair shop, not a dealer or a tire or other auto type specialty chain.

No, the shocks you just installed are too weak. Get the correct ones.

SOURCE: where are the spark plugs located on a 2000 Mercury Grand Marquis

There are eight COPs (coil-on-plugs) to remove. Using a 7mm or 9/32" socket, remove each bolt securing each COP to the intake manifold on top of the engine. Remove all eight COPs, and the spark plugs are underneath. When replacing the spark plugs, use only the proper Ford/Motorcraft plugs, even if they cost twice as much as the aftermarket ones. You will avoid further headaches this way. Hope this helps.

How do I replace the rear axle assembly in a 2000 Mercury Grand Marquis?


If you have air suspension, turn it off from the trunk. Put car on hoist and support rear axle. Make sure you support the axel well so the coil springs do not injure you when you remove the shocks and etc. Remove brake lines from brakes. Remove emergency brake cable from brakes. Remove sway bar link bolts to frame. Remove the bolts that hold axle to rear control arms. Remove rear shocks. ( these are a real pain ) Axle assembly can now be removed.

Can i chang air ride to shocks on 1996 mercury grand marques rear


You can change to regular shocks, without the air lines. Be sure to get adequate informationon weight of the vehicle. ( tire pressure & chart for front & rear on Driver door stille is a good place to look) It will give weight dimensions for front of the vehicle,loaded & unloaded (usually).

Have a chirping sound on drivers side of car while driving, sounds like its coming from either front or rear tire area. its a 2000 mercury grand marquis.


front or rear? thats a big area to narrow it down to. I would suspect the universal joints to "chirp" it may make more noise backwards or forwards.

I WOULD LIKE TO RAISE MY 2000 MERCURY MARQUIS BY FOUR INCHES, IS THIS EASY TO DO


Hello, Here is what you might try. First, go to DiscountTire.com and look at their tire comparison features on the Website. You will see "tools" that show what size tires will fit on your rims and what extra size rims will fit under your wheelwells. There is also a speed calculator for using the larger size tires over stock and it will show speedometer error if you do not recalibrate the speedo.

Next would be using spacers on the bottom of the springs or having longer springs refitted to your car. Finally air shocks front and back will give you some lift. The Grand Marquis can have rear air suspension, but to use it like you want, you will need to reconfigure the pump and change limit switches.

If you do all of this, you may reach your 4" lift. Your ride quality once you start changing springs and limiting travel in the suspension will probably deteriorate. As your car is a body on frame design, you may be able to put spacers of 1/2" to 1" under the body to frame mounts. You would need to make up the distance for the steering shaft, A/C lines and possibly hoses throughout.

In general, an inch from the tires, two inches from the springs or air shocks, and the balance from body on frame spacing.

I changed from the low 60 Series tires to a 65 Series tire on my own Grand Marquis. You can get a 70 Series to fit. I looked at Police car tires and they used 60 Series. But going back to 1994 Models, the 70 Series tire was available from the factory.

I hope my solution is very helpful to you in deciding what you to do.

I have a 95 grand marquis GS that floats around like a boat on the water, what do I have to get to fix this problem? does the car have struts and what about a bushing kit.


I had a 94, and now an 02, and have experienced some of the same problems. You would see a problem with the Bushings in tire wear. If you experience pulling or drifting to the same side as your last turn, have your balljoints checked.

Check your tire pressure, especially if this is a recent problem or you use a Quick change oil place. Make your tires harder by inflating them while staying below the Max amount. If you have tires with soft sidewalls the float will not go away.

The fronts have shocks. An alignment would show if bushings were needed. I put a 100,000 miles on my 94 after replacing the shocks, but they were replaced at 61000 giving the total 161,000 on the Air suspension. My 02 is still factory equipped.

This series of cars were durable vehicles. Any handling problem pointed to tires and Alignment. So far shocks are staying reasonable priced and you can get good deals on the Web, but deal with firms who give free shipping.
