Q: How to remove and install torsion bars on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?
A: To remove and install torsion bars, measure the ride height and mark the spot on the frame. Then, raise the front of the vehicle and count the threads showing on the torsion bar adjuster bolt. Install a puller on the torsion bar adjuster arm and turn the bolt until all tension is removed, then unscrew the adjuster bolt and remove the nut.
