    Q:
    How do you inspect and replace a upper ball joint on Buick Regal? Posted by Customer
    A:
    To inspect the ball joint, place a jack under each lower control arm between the suspension spring pocket and the ball joint, then raise the vehicle. Grasp the wheel at the 6 and 12 o'clock positions and shake it in and out, observing the steering knuckle for any movement relative to the control arm; if the ball joint is loose, it must be replaced. For removal and installation on vehicles built between 1986-87, a special installer, GM tool J-29193 or equivalent, is required. Begin by turning the lug nuts counterclockwise just enough to break the torque, then raise the vehicle and place jackstands under the frame before removing the wheel and tire. Support the outer edge of the lower control arm with a jack to manage the spring's down force, raising it just enough to free the upper control arm from the upper ball stud. Remove the cotter pin from the upper ball joint stud, loosen the nut without removing it, and use a ball joint removal tool to press the ball joint downward until the tapered portion is free from the steering knuckle. Wire the knuckle and associated parts in place to protect the brake hose, then remove the nut from the ball stud along with any washers. Lift the upper arm to free the ball stud from the knuckle, center punch and drill out the four rivets attaching the ball joint to the control arm, and use a hammer and chisel to cut off the rivet heads before removing the ball joint. For installation, place the new joint into the control arm and secure it with the provided bolts and nuts, torquing to 8 ft. lbs. (11 Nm). For vehicles built between 1975-85, maneuver the ball stud through the upper control arm, install the washer if applicable, and tighten the ball joint stud nut to 60-65 ft. lbs. (81-88 Nm), aligning a castellated hole with the cotter pin hole before installing a new cotter pin. For vehicles built between 1986-87, position the ball joint stud in the steering knuckle, install the tool, and tighten its operating nut to 30 ft. lbs. (41 Nm), then remove the tool and tighten the ball joint stud nut to 65 ft. lbs. (88 Nm), aligning the castellation with the cotter pin hole before installing a new cotter pin. Finally, reverse the remaining steps of the removal procedure to complete the installation.

    Q:
    How do you replace the upper balljoint on Chevrolet Astro? Posted by Customer
    A:
    To replace the upper balljoint, start by loosening the wheel lug nuts and raising the vehicle on jackstands. Remove the wheel and place a jack or jack stand under the lower control arm. Remove the cotter pin and back off the nut on the balljoint stud. Use a special tool or a fabricated equivalent to press the balljoint out of the steering knuckle. Drill holes in the rivet heads and use a drill bit to remove them. Knock out the rivet shanks and remove the old balljoint from the control arm. Position the new balljoint on the control arm and install the bolts and nuts provided. Tighten them to the specified torque. Insert the balljoint stud into the steering knuckle and tighten the nut. Install a new cotter pin and the bracket for the wheel speed sensor harness if necessary. Install the balljoint grease fitting and fill the joint with grease. Finally, install the wheel and drive the vehicle to an alignment shop for a front-end alignment check and adjustment if needed. For the lower balljoint, the process is different as it requires special tools. The lower control arm needs to be removed and the old balljoint pressed out and the new one pressed in.

    Q:
    How do you replace the upper ball joint on Chevrolet El Camino? Posted by Customer
    A:
    To replace the upper ball joint for models from 1969 to 1971, raise the car on a hoist or jack stands, remove the front wheel, and separate the upper and lower ballstuds from the steering knuckle using a balljoint separator or a thick bolt if necessary, ensuring the lower control arm is supported. Check for wear by reinstalling the nut and measuring the torque; if it's excessively high or low, replace the joint. Cut or grind off the securing rivets, clean the control arm, and install the new joint with the supplied nuts and bolts, tightening them to the specified torque. Reconnect the ballstuds to the steering knuckle, lubricate the new joint, reinstall the front wheel, and lower the vehicle. For models from 1972 to 1980, raise the front end, remove the wheel, and the upper ballstud cotter pin, then loosen the ballstud nut by one turn. Remove the ballstud nuts, swing the steering knuckle out of the way, and support the upper arm with a block of wood. Check for lateral play in the balljoint; if necessary, grind off the rivets carefully, install the new balljoint with the provided nuts and bolts, and torque-tighten. Align the ballstud collar pin hole, remove the wooden block, ensure the tapered hole in the steering knuckle is clean, and install the stud nut with cotter pin. Lubricate the joint. For the lower ball joint replacement, raise the front end, remove the ballstud cotter pin, and loosen the ballstud nut by one turn. Press out the balljoint stud, remove the lower stud nut, and free the knuckle from the ballstud while removing the wheel. Support the upper control arm with a block of wood, press out the lower balljoint using a vise and tubular spacers, and install the replacement balljoint with the air vent facing inwards. Align the ballstud cotter pin hole, remove the wooden block, ensure the tapered hole in the steering knuckle is clean, install the stud nut, torque-tighten, and lubricate the new joint before replacing the wheel and lowering the car.

    Q:
    How do you replace the upper and lower ball joints on Oldsmobile Cutlass? Posted by Customer
    A:
    In order to remove the upper ball joint, lift the front wheel of the automobile and later remove the wheel. Second, remove the upper ball stud cotter pin and then loosen ball stud nut one turn only. Pop out the ball stud using a ball joint separator or a tool that is fitting to get the job done and the lower control arm should be supported to prevent dropping due to spring pressure. Loosen and take off the upper ball joint stud and set the steering knuckle to the side. Place the upper arm in the air and hold it in position with a conveniently placed block of wood. Assess for movement in and out - observe whether there is any lateral play or if the head moves around in the socket; if affirmative then arthroplasty. To remove the rivets kindly use a grinding wheel in order to avoid causing a damage on the control arm or the ball joint seat. While refitting the new ball joint it is fixed on the control arm, then tightened with nuts and bolts with appropriate torque. Loosen at least one of the tension rods, put the car on the elevators to raise the front so that the ball stud collar pin hole is aligned with the length of the vehicle and then remove the wooden block. The ball stud has to be mated to the tapered hole in the steering knuckle, make sure that this hole is free from debris and damage. Fit the stud nut and tighten it to the required torque, then further tighten in order that the cotter pin holes line up and replace the cotter pin with a new one. Install a lubrication nipple and re-grease it as often as prescribed; afterwards, fit the wheel and lower the vehicle. As for the lower ball joint, it is necessary to jack up the front part of the car and then, turning the nut counter clockwise, to remove the ball stud cotter pin. As done to the upper ball joint, you have to press out the ball joint stud. Pry off the lower stud nut by opening it and loosen the knuckle from the bottom of the tire; pull the wheel and tire up at the same time. Raise the upper control arm and take out the wheel and put a wooden block of 2 x 4 inch in between the frame and the control arm. IN some circumstances it may be necessary to loosen or remove the tie-rod from the steering knuckle. Mount the appropriate size of a vise and tubular spacers to press the lower ball joint off from the control arm. If the Bleed vent is located on the new replacement ball joint facing inside the rubber boot then turn the ball stud cotter pin hole to the same direction as the length of the vehicle. Take out the wooden block and be sure that the tapered hole of the steering knuckle is intact and clean, then the ball stud nest into the steering knuckle. Screw the stud nut in place, torque tighten to values indicated then further tighten to align the pin holes for installation of a new cotter pin. Screw a lubrication nipple and put a recommended quantity of grease into it , then install the wheel and turn the tie-rod back in if it was removed; bring the vehicle back to the ground.
