To remove and install struts on your vehicle, follow these steps. Begin by disconnecting the negative battery cable. Then, raise and securely support the vehicle, ensuring it's supported by the frame with the control arms hanging freely. Remove the wheel and tire assembly. On Eldorado and Seville models, if equipped, detach the electrical connector from the top of the strut. On Deville and Fleetwood models, loosen the strut housing tie bar through bolts at each end. For Eldorado and Seville models with a 4.6L engine, remove the road sensing suspension position sensor from the lower control arm. Remove the nuts attaching the top of the strut to the body. For Deville and Fleetwood models equipped with anti-lock brakes, disconnect the wheel speed sensor and remove the sensor bracket from the strut. On Eldorado and Seville models, remove the stabilizer link from the strut, and also remove the brake line bracket from the strut. Finally, remove the strut-to-knuckle bolts and remove the strut while supporting the knuckle with wire to prevent damage to the ball joint or halfshaft. To install the new strut, attach it to the knuckle using the bolts and nuts. Then, attach the strut to the body with the nuts. For Deville and Fleetwood models, position the washer and tie bar before installing the strut-to-body nuts. Install the brake line bracket onto the strut. On Eldorado and Seville models, connect the stabilizer link to the strut. For Deville and Fleetwood models with anti-lock brakes, install the wheel speed sensor bracket and connect the sensor. On Eldorado and Seville models, install the road sensing suspension sensor to the lower control arm and connect the electrical connector at the top of the strut if it's equipped. Tighten the strut-to-knuckle bolts to 140 ft lbs (190 Nm), strut-to-body nuts to 18 ft lbs (24 Nm), stabilizer link nuts to 48 ft lbs (65 Nm), and tie bar through bolts to 20 ft lbs (27 Nm). Finally, install the wheel and tire assembly, lower the vehicle, and check and adjust the front wheel alignment as necessary. For overhauling the strut assembly, first, mount it in a strut compressor tool like J-34013 or an equivalent. Turn the compressor forcing screw until the spring compresses slightly. Use a T-50 Torx bit to prevent the strut shaft from turning, and then remove the nut on top of the strut shaft. Loosen the compressor screw while guiding the strut shaft out of the assembly. Continue loosening the compressor screw until you can remove the strut and spring. To install, mount the strut in the compressor tool, using clamping tool J-34013-20 or an equivalent to hold the strut shaft in place. Install the spring over the strut with the flat on the upper spring seat facing out from the centerline of the vehicle or in the same direction as the steering knuckle mounting flange. If the bearing was removed from the upper spring seat, reinstall it in the same position before attaching it to the strut mount. Turn the compressor screw to compress the spring while guiding the strut shaft through the top of the strut assembly. If necessary, use tool J-34013-38 or an equivalent to guide the shaft. When the strut shaft threads are visible through the top of the strut assembly, install the washer and nut. Remove clamping tool J-34013-20 from the strut shaft and tighten the strut shaft nut to 55 ft lbs (75 Nm) while holding the strut shaft with a T-50 Torx bit. Finally, remove the strut assembly from the compressor tool.

When installing the strut, ensure the wiring is upright and centered on the strut mount if equipped with Computer Command Ride. Tighten the strut tower mounting nuts to 19 ft. lbs. (25 Nm) and the strut-to-knuckle nuts to 140 ft. lbs. (190 Nm). Moisten the air line O-rings with lubricant and push the air line and connector fully into the fitting. Reattach the electrical connector if equipped with Computer Command Ride.
