  Q: How to remove and replace the front stabilizer bar on BMW 330i?

  A: On F-series chassis models, the front subframe must be lowered to allow the Sway Bar Kit to be removed. Block the rear wheels, apply the parking brake, then raise and support the front of the vehicle. Remove the engine under the shield and both front wheels. Unscrew the retaining nuts and free the connecting link from each end of the Sway Bar Kit. Make alignment marks between the mount bushings and the Sway Bar Kit, then loosen the Sway Bar Kit mounting clamp retaining nuts. Remove the nuts and clamps from the subframe, and maneuver the Sway Bar Kit out from underneath the vehicle. Remove the mount bushings from the bar. Carefully examine the Sway Bar Kit components for signs of wear, damage, or deterioration, and replace worn components as necessary. Install the rubber mount bushings to the Sway Bar Kit, aligning them with the marks made prior to removal. Maneuver the Sway Bar Kit into position and install the mounting clamps and new retaining nuts. Engage the Sway Bar Kit connecting links with the bar, ensuring correct location of the ball joint shank against the lugs on the bar. Install the new retaining nuts and tighten them. Install the brackets to the center of the Sway Bar Kit and tighten the bolts securely. Install the under-shield, then install the wheels and lower the vehicle to the ground. Tighten the wheel bolts to the specified torque.

  Q: How to remove and install the rear stabilizer bar on a BMW 330i?

  A: Remove both rear coil springs. Remove the control arm from the left-hand side and both traction struts. Remove the nuts and detach both sway bar kit links from the sway bar kit. Lower the rear subframe slightly to enable the sway bar kit to be removed. Remove the rear exhaust section mounts and heat shield. Disconnect the wiring for the rear ABS sensors and brake pad wear sensors at the junction on the rear subframe. Remove the bolts from the braces at each side securing the front of the subframe to the vehicle body. Use clamps on the rear brake flexible hoses, then disconnect the hoses from the rigid pipes. Support the rear subframe with a floor jack and suitable sections of wood. Loosen the subframe mounting bolts and lower the subframe as much as possible without placing any strain on the brake hoses. Make alignment marks between the mount bushings and sway bar kit, then loosen the sway bar kit mounting clamp retaining bolts. Remove both clamps from the subframe and maneuver the sway bar kit out from underneath the vehicle. Remove the mount bushings from the bar. Carefully examine the sway bar kit components for signs of wear, damage or deterioration, paying particular attention to the mount bushings. Replace any worn components as necessary. Installation: Install the rubber mount bushings to the sway bar kit, aligning them with the marks made prior to removal. Raise the sway bar kit and maneuver it into position. Install the mounting clamps and the bolts. Ensure that the bushing markings are still aligned with the marks on the bars, then securely tighten the mounting clamp retaining bolts. Installation is the reverse of removal noting the following points: Replace all self-locking nuts. The traction strut and control arm bolts/ nuts should only be tightened when the rear suspension has been raised with a floor jack to simulate normal ride height. Tighten all fasteners to their specified torque where given. Reconnect the brake hoses and bleed the hydraulic system. Have the rear wheel alignment checked at the earliest opportunity.
