If your Buick, Cadillac, or Pontiac is starting to feel every bump in the road or making weird noises when turning, this SCITOO 8-piece suspension kit is exactly what you need. This complete set includes 2 wheel hubs (part number 513121), 2 front outer tie rod ends (ES3452), 2 front inner tie rod ends (EV260), and 2 front sway bar end links (K5255). It fits a bunch of GM vehicles including 2000-2005 Buick LeSabre, 1998-2005 Buick Park Avenue, 2000-2005 Cadillac DeVille (except HD suspension), 2000-2005 Pontiac Bonneville, and several others - just check the full compatibility list to make sure it works with your specific vehicle. All the parts come pre-greased and ready to install, saving you time and hassle. The wheel hubs feature ABS sensors and have a 5-bolt pattern with 3-bolt triangular flange. Replacing worn suspension components will eliminate steering noises, improve handling, reduce that 'floating' feeling over bumps, and make steering crisp and responsive again. Whether you're a DIY mechanic or taking it to a shop, this kit gives you everything you need in one package at a much better price than buying individual parts. Your car will drive like new again with fresh suspension components that restore that solid, planted feel on the road.
