Fig. 3 - Checking Rear Ride Height
Checking Rear Ride Height
Measure rear ride height with the vehicle unloaded (no luggage or passengers) and with the fuel tank full.
Place the vehicle on a level surface and measure the vertical distance between the top of the axle tube (C) and the underside of the frame sill (D) inboard
of the jounce bumper (E).
With Standard or Soft Ride Suspension, vertical distance should be 15 cm (6 inches) plus or minus 13 mm (1/2 inch). With Heavy Duty Suspension,
vertical distance should be 18 cm (7 inches) plus or minus 13 mm (1/2 inch).
If rear height is not within specified limits, a spring change may be necessary. Changing spring rate by one letter code will generally increase/decrease
rear height by 13 mm (1/2 inch).
Adding Accessories To The Vehicle Front End
Measure ride height before and after installing accessories such as a winch, snow plow, or air conditioning kit. If ride height is not within limits after
accessory installation, a spring change will be necessary.
NOTE:
Front air shocks must also be added whenever a snow plow kit is installed on Cherokee/Wagoneer models.
An example of the spring selection process after adding an accessory is outlined in the following example.
Example:
Vehicle is a two-wheel drive Cherokee with Standard suspension. Front spring codes are FG (passenger side) and FH (driver's side).
Height specification for two-wheel drive models is 17 cm (6 3/4 inches) plus or minus 13 mm (1/2 inch).
Front ride height before installing the accessory is 16.5 cm (6 1/2 inches) at both sides.
Install the accessory and recheck front ride height.
Front ride height is now 15 cm (6.0 inches) which is below specified limits.
Correct ride height by installing code FH spring on the passenger side and installing code FK spring on the driver side. Increasing spring rate by one
code letter will raise height by approximately 9.5 mm (3/8 inch).
