The Trailblazer name was originally used for a certain trim level on the Chevy Blazer. Chevy discontinued the Blazer and turned the Trailblazer into it's own model in 2002. The Trailblazer was originally offered with a 4.2-liter, inline six-cylinder engine, but Chevy later integrated a 5.3-liter, V-8 into the SS Sport trim level. The 2006 Trailblazer uses a stabilizer bar to link the left and right suspension together to prevent excessive body roll. The stabilizer bar is connected to the rear axle housing and the links connect the bar to the frame on either side of the vehicle.
Items you will need
- Wheel chocks
- 3-ton floor jack
- Jack stands
- Socket set
- Torque wrench
Park the vehicle and engage the parking brake. Kick a set a wheel chocks on either side of both front tires. Place a 3-ton floor jack under the center of the rear differential and lift the rear end. Place jack stands under the axle housing. Lower the jack until the axle rests on the jack stands.
Remove the stabilizer link-to-stabilizer bar nut with a socket and ratchet. Remove the link nut at the frame. Tilt the link out of the frame mount, then remove it from the stabilizer bar. Repeat this step for the opposite sway bar link and allow the sway bar to hang down.
Inspect the sway bar bushings where it is mounted on each side of the axle. If the bushings are cracked, if they move freely between the axle and the bar, or are missing, replace them before continuing. Inspect the sway bar from end to end. If the sway bar has excessive corrosion, is bent or damaged in any way, replace it before continuing.
Compare the old links with a new set – they are side-specific. The link stud that attaches to the sway bar always points toward the tire on that side of the vehicle. Install a new link to the sway bar and loosely install the nut. Rotate the sway bar towards the frame mount and install the link stud to the frame hole. Loosely install the nut. Repeat this step for the opposite side.
Tighten the link to frame nut on each link to 66 foot-pounds with a torque wrench, then tighten both link to bar nuts to the same torque. Lift the rear end by the differential housing and remove the jack stands. Lower the truck to the ground.
- New sway bar kits are commonly sold as a complete replacement with new mounts, bushings and links.
- The front sway-bar links are replaced the same way as the rear links, but the nuts need to be tightened to 114 foot-pounds.
