How to tighten rear axle

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! A loose rear axle on your 2008 Buick LaCrosse? That’s like trying to ride a bike with wobbly training wheels—not ideal. If a mechanic told you it's loose, they probably meant there’s play in the suspension or axle mounts. Tightening things down may involve checking the rear control arms, bushings, and bolts holding everything together. If you're hearing bumps, it’s worth getting those fasteners torqued to spec and maybe swapping out any worn bushings before things get... bumpier.
