What is the lug nut torque on a 2003 Buick?

There's no single lug nut torque specification for all 2003 Buick models. The torque value depends on the specific model (Century, LeSabre, Rendezvous, Regal, Park Avenue, Rainier, etc.) and even the wheel size and type (steel vs. alloy).

To find the correct torque specification, you MUST consult your owner's manual. This manual will provide the precise torque value recommended by the manufacturer for your specific 2003 Buick.

Failing that, you can:

* Check the sticker on the driver's side doorjamb: Sometimes, the tire pressure and other vehicle information, including lug nut torque, is listed there. However, this is not always the case.

* Consult a reliable online repair manual: Sites like Chilton or Haynes often have repair manuals specific to your vehicle's year, make, and model. Be sure it's a reputable source.

Using the incorrect torque can lead to loose wheels (dangerous!) or damaged wheel studs. Always prioritize finding the correct specification before tightening your lug nuts.
