The arm might be loose after the bolts are removed, so make sure you have your hands on it. It is possible to remove the lower control arms bolt using a universal joint and socket. These bolts are very tight, so ensure that the socket or wrench is secured on the bolt head to prevent rounding. A few bolts have a nut at the back that must be held in place by an additional wrench. To loosen the bolts, use a wrench or socket measuring 19 mm to 22 mm. There will be two bolts for mounting control arms, either horizontally or vertically. The control arm is an extremely rigid component and designed to take a hit. This will ensure that the swaybar link stays out of the way throughout the entire job. A lower control arm or A-arm is a piece of the suspension that is holding the wheel and other suspension components in place. For the rear of a vehicle with a solid axle, any style of control arms might be used to connect the rear axle to the frame or unibody. This also means one less ball joint, and a couple less rubber control arm bushings to worry about. Many front-wheel drive vehicles only use a lower control. An upper control arm isn't needed because the strut takes its place. Most vehicles use either one or two control arms per wheel, on both the front and rear suspension. Grab the swaybar link and pull it off the lower control arm mount. Lower Control Arms When a vehicle has a MacPherson strut style front or rear suspension, lower control arms are the only type used. Use a wrench or socket to remove the nut. This connection could have a small taper, so you might need to shock it loose like the ball joint. The swaybar link will connect to the control arm.
#LOWER CONTROL ARM UPGRADE#
If you are using "live spring" suspension (shock), the lower control arm must first be held by a hydraulic Jack and then slowly lowered after the ball joint has been released. The JXB Front Lower Control Arm Upgrade is the only kit to replace both factory bushing locations with precision motorsport grade PTFE-lined spherical bearings. Next, use a hammer to loosen the control arm bulkhead or spindle taper. After the cotter pin is removed, loosen the ball joint nuts. This can be done with a wrench between 20 and 24mm, or a socket. Protective eyewear and gloves are recommended. Start by taking off the wheel, lifting the car onto jack stands, and supporting it.
#LOWER CONTROL ARM HOW TO#
First, you need to know how to remove a lower control arm. This joint will need to be replaced with the control arm. The ball joint is often built into control arms. You can inspect these bushings by lifting the car and looking for irregularities in the rubber center. They will eventually wear out and become damaged. These bushings can be affected by driving habits and road conditions. They are bolted onto the frame by bolting them to the pivot point. Two rubber bushings at the pivot point are used to transfer the car's weight through the control arm.
