Re: How to tell when coil springs are shot?
Marcel,
Unless you tow a LOT, the springs are probably fine. They are not bad to
replace at all. One bolt while the shocks are off. Does the rear end sag?

Yeah the rear does sag a bit, ever since I towed a 4,500lb trailer 1200
miles several years ago.
The Haynes manual makes it look a lot harder than removing one bolt.
They have me disconnecting the rear drive shaft from the rear
differential shaft yoke. Unbolt the lower suspension arms from the axle.
Unbolt the stabilizer bar links and shock absorber. Disconnect the track
bar from the axle bracket.
Are the folks at Haynes making it sound more difficult than it really
is?.....I sure hope so.

For the '95 which should be pretty similar, the factory manual has only
a few steps.
1. Lift the vehicle, then put a hydraulic jack under the axle
2. Disconnect the stabilizer bar link and shock absorber from the axle
bracket
3. Disconnect the track bar from the frame rail bracket
4. Lower the axle until the spring is free of the upper mount seat,
then remove the coil spring retainer bolt and then remove the spring.
Probably a good idea to pick up a new isolator and bushings, grommets,
etc. for the track bar and stabilizer bar, possibly even shock bushings
while doing this.

Re: How to tell when coil springs are shot?
Marcel,
This is the procedure from the '96 ZJ factory manual Section 2 page 14:
http://i112.photobucket.com/albums/n...Suspension.jpg
COIL SPRING
REMOVAL
(1) Raise and support the vehicle. Position a
hydraulic jack under the axle to support it.
(2) Disconnect the stabilizer bar link and shock
absorber from the axle bracket.
(3) Disconnect the track bar from the frame rail
bracket.
(4) Lower the axle until the spring is free from the
upper mount seat. Remove the coil spring retainer
bolt (Fig. 2) and remove the spring.
INSTALLATION
Inspect isolator the for damage or wear. Replace
the isolator if necessary before installing spring.
(1) Position the coil spring on the axle pad. Install
the spring retainer and bolt. Tighten the bolt to 22
N·m (16 ft. lbs.).
(2) Raise the axle into position until the spring
seats in the upper mount.
(3) Connect the stabilizer bar links and shock
absorbers to the axle bracket. Connect the track bar
to the frame rail bracket.
(4) Remove the supports and lower the vehicle.
(5) Tighten the brack bar and shock absorber to
specified torque.
For more detailed instructions with step by step pictures Google"'ZJ Budget
Boost" The only difference is instead of adding a spacer you are replacing
the whole spring.
