The Buick LaCrosse, first introduced in 2004, played a crucial role in revitalizing Buick's line-up amid an industry-wide recession. Targeting a younger demographic, this mid-size, four-door model initially offered two versions: the CX and CXL, equipped with a 3.8L, 200-horsepower V6 Series III engine, and the more advanced CXS, featuring a 240-horsepower 3.6L V6. Launched in 2005, the first generation utilized a 4T65-E automatic transmission, delivering power to the front wheels. It underwent significant changes in 2010, marking a new era for the brand with features such as a chrome package, factory remote start, and an adjustable steering column as standard. The second-generation LaCrosse, designed to be the brand's flagship, is based on a variant of the Epsilon II long-wheelbase chassis and derived from the 2008 Invicta concept. It introduced the first front suspension in North America and innovative powertrains that attracted younger buyers. Notably, the second generation brought the eAssist hybrid system, reducing fuel consumption without sacrificing performance. The model also underwent a significant weight reduction through the use of high-strength steel and better soundproofing materials. With standard safety features like ten airbags, the Buick LaCrosse emerged as a model of its own right, defining a new beginning for the Buick brand.

Like any vehicle, the Buick LaCrosse has its share of issues that become apparent over time, which is common across all brands. Notably, owners have reported problems with the suspension system, where the gear indicator doesn't align correctly with the selected gear, causing issues like the inability to remove the key from the ignition or the car not going into gear at all. This is typically a problem with the shift cable that requires inspection. Another frequent issue revolves around the air conditioning system, particularly noticeable after the car has covered significant mileage. Symptoms range from persistent frost from the vents and an increased cabin temperature to a noisy compressor or a compressor clutch that doesn't move. These issues could arise from a faulty A/C compressor or A/C expansion valve. Over time, other components such as the windshield wiper or wiper blade may underperform, and seat belts may require replacement after an accident.

Original equipment manufacturer parts are the best in terms of quality. Manufactured using the top materials to ensure their durability, genuine parts are the #1 choice to keep your vehicle at peak performance. They are also designed to match official Buick factory specifications for easy installation and a snug fit.

Buick LaCrosse Parts Questions & Answers

  • Q: How do you remove the tie-rod end?
    A: To remove the tie-rod end, start by loosening the wheel lug nuts and raising the front of the vehicle. Support it securely on jackstands and apply the parking brake. Block the rear wheels to prevent the vehicle from rolling off the jackstands. Remove the wheel. Then, loosen the tie-rod end jam nut and mark the relationship of the tie-rod end to the threaded portion of the tie-rod. This will ensure the toe-in setting is restored when reassembled. Loosen the tie-rod end ball stud nut and use a puller to separate the ball stud from the steering knuckle arm. Once the ball stud is loose, remove the ball stud nut and completely separate the tie-rod end from the steering knuckle arm. Unscrew the tie-rod end from the tie-rod. To install the tie-rod end, thread it onto the tie-rod to the marked position and insert the tie-rod end ball stud into the steering knuckle arm. Install the nut onto the ball stud and tighten it to the specified torque. Tighten the jam nut securely and then install the wheel. Lower the vehicle and tighten the lug nuts to the specified torque. Finally, have the front-end alignment checked and adjusted if necessary.
  • Q: How to check the condition of the balljoint on Buick LaCrosse?
    A: To check the condition of the balljoint, start by raising the front of the vehicle and securing it on jackstands. Apply the parking brake and block the rear wheels to prevent rolling. Use a prybar to test for excessive movement between the balljoint and steering knuckle. Additionally, have an assistant move the top of the tire in and out while checking for movement at the balljoint stud nut. If excessive movement is detected, further measurement with a dial indicator is recommended. For the removal of 2009 and earlier models, mark the control arm's position, loosen the lug nuts, and remove the wheel. Separate the balljoint from the steering knuckle and remove the control arm from the subframe. Drill out the rivets securing the balljoint, remove it, and clean the control arm. To install a new balljoint, secure it with the provided fasteners, attach the control arm to the subframe, and place the ball stud into the steering knuckle. Tighten the castle nut, raise the control arm to simulate normal ride height, and tighten all fasteners. For 2010 and later models, the balljoint is not serviceable separately, so the entire control arm must be replaced.
  • Q: How do I remove and replace the control arm?
    A: For 2009 and earlier models, the removal of the control arm involves marking the relationship of the control arm to the subframe while the vehicle is at normal ride height. After loosening the wheel lug nuts and raising the front of the vehicle on jackstands, the wheel is removed. If equipped, the ABS wheel speed sensor and harness are disconnected or removed from the control arm. The balljoint is separated from the steering knuckle, and the control arm-to-subframe fasteners are removed to separate the control arm from the subframe. During inspection, the control arm and bushings are checked for wear and distortion, and any damaged parts are replaced. Installation is the reverse of removal, with all fasteners tightened to the torque specifications, and a front wheel alignment check and adjustment is recommended if necessary.
  • Q: How do you remove the steering wheel?
    A: To remove the steering wheel, start by parking the vehicle with the wheels pointing straight ahead and disconnecting the battery. Disable the airbag system and remove the steering column covers. Use a thin round tool to release the retainer and gently pull the airbag module towards you. Disconnect the electrical connectors and remove the airbag module. Detach the clock spring wire harness and disconnect the electrical connector for the steering wheel switches. Remove the steering wheel nut or bolt and lift the steering wheel. When installing the clock spring, make sure the wheels are straight ahead. Center the clock spring by rotating the hub clockwise until it stops, then counterclockwise until the centering window turns yellow. The rest of the installation is the reverse of removal, ensuring proper alignment of the steering wheel and tightening the nut or bolt. Finally, install the airbag module and enable the airbag system.
