REAR AIR COIL.

Suspension problem
1995 Lincoln Town Car V8 Two Wheel Drive Automatic 199375 miles

I changed out the front coil springs and front shocks and rear shocks. When the air coils are inflated it looks like the front is slightly higher than the rear. Do the rear coils loose hieght over about 15yrs, or are my new front coils not OEM replacement. The front coils are about 1.5 inches higher than the old ones.

ADJUSTMENTS
RIDING HEIGHT

WARNING: DO NOT remove air spring under any circumstances when air spring is pressurized. DO NOT remove components supporting air spring without releasing air. Air suspension system must be shut off prior to hoisting, jacking or towing vehicle. Air suspension system can be deactivated by disconnecting battery or turning air suspension service switch to OFF position. Air suspension switch is located on left side of trunk area. Failure to deactivate air suspension system may result in unexpected inflation or deflation of air springs, causing vehicle to shift.

Front & Rear
1.Place vehicle on alignment rack or hoist that supports vehicle on tires. Ensure air suspension switch, located on right side of trunk, is on. Open driver's door and turn ignition on.

2.Add weight to rear bumper. Rear of vehicle will rise to trim position. After trim height is reached (air compressor stops), remove weight from rear bumper and close driver's door.

3.Vehicle will now lower to correct ride height. Rock vehicle sideways to remove effect of suspension friction, and allow it to settle.

4.Turn air suspension switch off. Grind weld flash from inboard frame reinforcement rail surface as necessary. This is done in order to get an accurate height reading. See Fig. 1.

5.Measure and record dimension vertically between axle tube and inboard reinforcement rail (dimension "D"). See Fig. 2. If ride height is within specification, no adjustment is necessary.

If riding height is not within specification, go to next step.
RIDING HEIGHT SPECIFICATIONS Application In. Town Car 4.72-5.27 (119.8-133.8) (mm)
Models With Optional Towing Package 4.80-5.43 (121.8-137.8)(mm)

6.Working on left side of vehicle, position Height Gauge (T90P-5995-B) on axle tube. See Fig. Hold height gauge in place and loosen set screw. Slide gauge post up until it contacts frame inboard reinforcement rail. Tighten set screw and remove height gauge by rolling it rearward off axle tube.

7.Read gauge height (dimension "D") on height gauge and determine if dimension "D" is within specification. See the RIDING HEIGHT SPECIFICATIONS table. Ride height is adjusted by moving rear height sensor attaching bracket up or down, based on left rear upper control arm position. 8.An adjustment slot is provided on the bracket to adjust up or down as necessary. See Fig. 3. Adjusting sensor attaching bracket one index mark will change riding height, or vertical dimension "D", approximately .35" (9 mm). After adjustment is made, repeat step 5).

Thansk for the info, whood a thought. So do I keep doing this adjustment procedure untill the ride of the car looks O.K, eg.(Rear looks a little higher than the front or should they be the same hiegth. Is there a measurment that I have to take from the front before I make the rear adjustment. Wher do I get the rerar measuring tool and what is it called.

Thanks

You can use any available measuring tool you have to obtain the measurement
make sure its on a flat surface or an alignment lift
check last picture it shows how to lower or raise it
