1. Raise and support vehicle. Remove wheel assembly. Disconnect brakeline bracket from strut assembly. Support control arm. Remove strut-to-steering knuckle bolts. Separate strut from steering knuckle. 2. Remove dust cap from top of strut. See Fig. 5 . Remove strut-to-body nuts. Remove strut assembly from vehicle. If no mark is present, mark bottom edge of coil spring for reassembly reference. Fig. 5: Exploded View Of Strut Assembly (Elantra & Tiburon Shown; Others Are Similar) Disassembly Mount strut assembly in vise. Compress coil spring using coil spring compressor. Remove self-locking bearing nut with Spanner Wrench while holding upper spring seat. See SPECIAL TOOLS table. Remove insulator and spring seat. Remove rubber bumper and dust cover. See Fig. 5 . Slowly release coil spring compressor tension. Remove coil spring. Inspection Check parts for deterioration or damage. Check strut assembly for leaks and proper operation. Replace strut if fluid leakage exists. Replace worn or damaged parts. Reassembly 1. To reassemble, reverse disassembly procedure. Place coil spring identification mark toward knuckle. Ensure “D” shaped upper seat hole is aligned with notch in piston rod. Align coil spring ends in spring seat grooves. 2. Pack insulator bearing with grease and install dust cap. Avoid getting grease on insulators. Compress coil spring. Install rubber bumper and dust cover, spring seat and insulator. Using spanner wrench, tighten strut piston assembly lock nut to specification. See TORQUE SPECIFICATIONS . Installation To install, reverse removal procedure. Ensure strut assembly and steering knuckle mating surfaces are clean. Tighten fasteners to specification. Check front end alignment. See SPECIFICATIONS & PROCEDURES article in WHEEL ALIGNMENT.

STRUT/SHOCK ABSORBER CAUTION: Removal 1. With vehicle on floor, remove plastic cap which covers upper strut/shock retaining nuts. Remove strut/shock retaining nuts. Slowly raise vehicle until weight is off spring. Remove bolt which retains lower end of strut/shock absorber to axle beam mount. Raise vehicle until strut/shock can be removed. Place strut/shock assembly in vise. 2. Hold piston rod. Remove strut/shock retaining nut and related components. See Fig. 1 . Remove slotted nut (some models). Remove spacer and coil spring. If coil spring is to be replaced, ensure paint stripe color on replacement spring matches original spring color stripe. Installation 1. Install protective cap and tube onto shock absorber. Install rubber buffer with small end downward. Install snap ring and washer. Place spring into lower seat. Install upper retainer with spacer sleeve. 2. Tighten slotted nut (some models) which retains piston rod. Install upper mounting hardware. Tighten piston rod. To complete installation, reverse removal procedure. Tighten bolts and nuts to specification. See TORQUE SPECIFICATIONS. SUSPENSION ASSEMBLY CAUTION: DO NOT remove both suspension strut/shock absorbers at same time. When removing suspension assembly, add weight to rear of vehicle to prevent tipping due to change in center of gravity.

CAUTION: The vehicle must be standing on its wheels when removing the upper shock absorber mounting. 1 Detach upper shock absorber mounting. Model 140: Counter piston rod with Alien wrench (WAF 5). NOTE: Installation: Replace self-locking nut (11a). 2 Remove plate (11b) and rubber mount (11c). 3 Raise vehicle. 4 Detach shock absorber (11) from wishbone (31) and remove downwards. CAUTION: Installation: Replace self-locking nut (11u). 5 Remove mounting parts (11y, 11d, 11f, 11h) for shock absorber (11). 6 Check shock absorber. 7 Install in the reverse order. Remove/install Rear Shock Absorber CAUTION: Installation: Replace self-locking nuts and bolts. 1 Detach upper shock absorber mounting NOTE: The vehicle must be standing on its wheels when removing the upper shock absorber mounting. 2 Remove plate (75b) and rubber mount (75c) 3 Raise vehicle. 4 Remove rear axle switch for roll bar 5 Remove spring link cover (72c). 6 Detach damper (75) from spring link 7 Remove attaching parts (75k, 75d, 75f, 75i) of damper (75) 8 Shock absorber inspection 9 Install in the reverse order
To replace a strut back into the MacPherson suspension, proceed as follows: 1. Extend the piston rod on the new strut (or cartridge) to its full length. 2. Reinstall the coil spring and other components in the reverse order that they were removed. Make sure the spring is positioned properly on the lower spring seat. MODIFIED MACPHERSON STRUTS To replace a strut on a modified MacPherson suspension, proceed as follows: 1. Raise the car and support the lower control arms with a jack or jack stands. 2. Remove the upper shaft nut, but not the upper strut mount retaining bolts. If a mount rivet is used, do not remove it either. 3. Remove the brake caliper. If necessary, unbolt the strut from the spindle. 4. Remove the strut assembly and upper mount. Discard the strut assembly. 5. If the upper mount has a rubber jounce bumper inside the dust shield, inspect it and replace if damaged.

Exploded View Of Rear Suspension Assembly.1. Remove rear seat cushion and backrest. 2. Raise and support vehicle. 3. Remove rear wheels. 4. Disconnect brake hose from brake caliper. 5. Remove lower and upper strut mount retaining bolts, then the strut assembly. 6. Mount strut assembly in a suitable spring compressor. Ensure projections on compressor are seated on inner diameter of spring. 7. Compress spring until tension is relieved from spring seats. 8. Remove strut rod self-locking nut using a suitable socket wrench and spanner wrench tool No. 926510000 or equivalent. 9. Remove upper strut mount. 10. Slowly release spring tension, then remove coil spring, dust cover and helper from strut body. 11. Reverse procedure to install, noting the following: a. Mount coil spring with flat face toward lower spring seat. b. Use caution not to scratch piston rod. c. Install strut rod with new locking nut.
d. Refer to Figs. 7 and 8 for torque values. e. Bleed brake hydraulic system. Pneumatic Suspension
