YOU MEANT GRAD CHEROKEE.
wrong springs,
shocks are not springs at all they are just motion dampeners.
the put new coil springs rear
means THEY? who is they, ok a shop.
They DID I WRONG, TAKE IT BACK
Did you got to a Low RIder shop? LOL !
they should not have ever put in coil sparings
unless you said car rides lower than stock.
or told them to on a whim
or they cheated you. (called building ticket in the business) evil.

My question would be why do you want to lift it ? Is it a four wheel drive are a two wheel drive ? Factory seating it will except a large wheel without any modifications . The 2010 dodge ram 1500 uses a coil spring in the rear and a spring and shock on the front if you use a spacer it will mess up the ride and the handling of the truck. Before you do any modifications to the ride height of the truck talk to your local dealer and ask them. Good luck.

shocks air bags put some wood spacers made from pine wood 2x4s or 1x3" while the springs jacked up let the cr down see the wood is thick enough to be squuezed as you lower body down test the car by driving with the wood plankes in the springs raiseing the height of the car if problemis fixed then oder spring spacers or air shock kit or simply leave the wood in till it falls out

Most likely spring.... look under and make sure it didn't break off from the car frame or crack.... check to see if the shock popped through the body.... the spring holds the car away from the tires and the shock stops the car from bounceing... also check to see if the rear stableizer didn't let go.... this keeps the tire in the upright position.

The shocks do not set ride Hightower. The leaf springs set ride hieght in the rear. So ether the leaf springs are worn out or the shackles that hold the springs to the frame are broken (should be very obvious if they are). Most likely the rear leaf springs are the problem.

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.

Removal & Installation To Remove:

1. Before servicing the vehicle refer to the precautions at the beginning of this section
2. Loosen the lug nuts on the wheel and tire assemblies but do not remove the lug nuts
3. Raise and support the vehicle
4. Remove or disconnect the following:
   • Wheel and tire assemblies
   • Axle lubricant into a suitable container
   • Rear driveshaft
   • Parking brake cable
   • Brake calipers
   • Shock absorbers from the axle brackets
   • Vent hose from the rear axle vent fitting
   • Nuts and the washers from the U-bolts
   • U-bolts, spring plates and spacers from the axle assembly
5. Lower the axle assembly from the vehicle

To Install:

1. Place the rear axle assembly under the vehicle
2. Align the rear axle assembly with the springs then connect the spacers, spring plates and the U-bolts to the rear axle
3. Raise the rear axle assembly into position
4. Install or connect the following:
   • Washers and nuts to the U-bolts; Torque to: 59 lb-ft. (80 Nm) then, Torque to: 89 lb-ft. (120 Nm)
   • Vent hose to the rear axle vent fitting
   • Shock absorbers to the rear axle
   • Brake calipers (See: Brake Caliper)
   • Parking brake cable (See: Parking Brake Cable)
   • Rear driveshaft (See: Rear Driveshaft)
   Wheel lug nut tightening sequence
   
   
5. Fill the rear axle with lubricant
6. Bleed the brake system (See: Brake Bleeding)
7. Install the wheel and tire assemblies
8. Lower the vehicle to the ground
9. Torque lug nuts as follows:
   • Single Wheel: Torque to: 140 lb-ft. (190 Nm)
   • Dual Wheel: Torque to: 175 lb-ft. (240 Nm)
10. Road test the vehicle to check performance

You can get a decent pair of gas charged shocks or monroe load leveler shocks (if they are available for your car) However, it's likely that the rear springs have sagged. You can easily replace them with either oem or a stronger variable rate spring.

I have had the same symptom on my 1994' 960 (sedan).

I thought (told by the dealer) the shocks had worn out (although the car was only 110000 km !...), so I had the dealer change them (they had a promotion). It did not change much of anything, except it lifts a little bit more (about 1 cm more), but still "sags" after about 1/2 hour.
It takes about 1 km driving to pump back up.

I have never been observing that symptom on nivomat-equipped 940 wagons with solid rear axles, and knowing that 960 sedans (with multilink rear suspension) having nivomat wider (3.5") than rear solid axle wagons (940 and early 960) which are 2.5".

So, my interpretation is those wider ones support a great deal of the weight, even more that of 940 wagons, so they react differently by sagging more, due to internal micro-leaks.
Also, and consistently, springs with nivomats are thinner and they may also wear out faster than on standard supension, putting even more load on nivomats to compensate.

Therefore my conclusion was :
- It is not because of the shocks,
- It may be the springs
- It is not really a problem, is it ?

locate the ride height control sensor box with a small rod connected to the rear control arm. this rod needs to be loosened and raised about 1 and 1/2 inches, and tightened in place. this will only work if your rear load leveling still works on the car, as the air shocks are pumped up resulting in a lift w/out fuckin up the whole car
