B2300 SE Regular Cab 2WD L4-2.3L VIN A (1997)
2. If the difference between left and right ride heights exceeds 16 mm (5/8 inch) and is less than 20 mm (3/4 inch), measured at the wheel house
opening to ground, add one shim to the side of the vehicle that is low.
NOTE: The shim is to be placed under the lower spring seat.
3. If there is a computed side-to-side difference of 20 mm (3/4 inch) or more in the left/right wheel house openings, swap springs from side-to-side.
NOTE: If the lean condition follows the spring (lean now on other side of the vehicle), one or both springs are out of specification. Replace both
springs with new ones. If lean condition remains unchanged, something other than a bad spring is the cause and must be diagnosed.
NOTE:
^
A side-to-side lean at the rear of the vehicle can be adjusted by approximately 6 mm (1/4 inch) by installing a shim between the rear spring and
axle on the low side of the vehicle.
^
A "low at the rear" vehicle can be raised approximately 6mm (1/4 inch) by installation of one shim on each side.
REAR LEAN
1. Raise the vehicle until the weight is off the rear springs but with the tires still touching the floor.
2. Loosen the spring U-bolts to allow the axle to separate from the spring approximately 13 mm (1/2 inch).
3. Position the shim between the spring and the spring seat with the tie bolt head through the hole in the shim.
4. Make sure the spring leaves are properly aligned and the spring U-bolts contact the edges of the spring assembly or axle seat.
5. Tighten the spring U-bolt sufficiently and make sure the spring bolt head extends through shim into axle seat hole.
