How to remove Trailing Arm for 2009 and earlier Buick LaCrosse?

For the removal of Trailing Arm 1, first release the rear wheel lug nuts and secure the front wheels. Next, lift the back of your vehicle and set it up on sturdy jackstands. Remove the rear wheels as well as the back part of the exhaust system. Lastly, unhook from stabilizer bar link at stabilizer bar and if there is any disconnect ABS wiring harness clips from arm. On trailing arms' rear knuckle remove mounting fasteners for both trailing arms and detach both arms from knuckle. Take off hydraulic brake line from above of rear suspension support and place a floor jack under it. Raise this until only touch its center with that support just a bit higher to make sure it does not slip out when a bolt is removed in step seventeen below. Unbolt rear suspension support on same side that arm is being removed from and loosen bolts on opposite side of support. Lower slowly with floor jack until trailing arm's mounting fasteners can be reached by you in case if required put one big bolt through last hole so that after flooring we will use that bolt to pull beam down safe .A pipe clamp put around top so we could tighten them all together so that they won't move apart anymore but check also what kind of other connections may exist between parts here.Put a stack or 2x4s on ground next to where jack will stand take stand out place directly under blue lifting device . Now go ahead remove remaining nuts completely before taking even larger ones loose then look carefully inspect bushings both sides neatness because if necessary replace these things (two small metal inserts into rubber) otherwise don't take anything off yet or else would be forced having them repaired pretty soon anyway. For Trailing Arm 2 follow exactly the same steps like those followed for Trailing Arm 1.To remove Trailing Arm, take out bracket-to-body mounting bolts and trailing arm-to-knuckle mounting fasteners of trailing arm. Finally, remove the trailing arm and check the condition of its bushing. Take it for bushing replacement if necessary.

Buick LaCrosse Trailing Arm

The rear suspension of the Buick LaCrosse links the rear axle to the chassis via a Trailing Arm. This stabilizes the rear axle. As a result, over bumps, a sedan can track straight. Moreover, it improves cornering response. The initial models applied a Trailing Arm arrangement on a live rear axle. Coupled with the helpful Panhard rod, the two stout links ensure the wheels stay centered side to side. Additionally, the single front pivot allows the wheels to swing up and down. Later versions of the LaCrosse applied an independent rear suspension with the use of a Trailing Arm. Each wheel rides on a large triangular Trailing Arm fixed ahead of the hub. It makes for a quieter ride in cars like the LaCrosse. Though some model years featured a semi-trailing arrangement with two separate pivot points that angled the arm, this design offered the bump-absorbing freedom of independent designs combined with the sturdy toe control of earlier designs. No matter the design, every Trailing Arm fitted to a Buick LaCrosse prevents unwanted axle shifts, maintains tire contact, and opens up cabin space by omitting bulky crossmembers, so the tough Trailing Arm keeps providing the comfortable handling and nimbleness drivers expect from a modern Buick sedan.

Each OEM Buick LaCrosse Trailing Arm we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
