Preventive Maintenance Tips for the 1999 Chevy C1500

The C1500's steering and suspension components are robust but wear predictably. Make it a habit to listen for new clunks and groans and to visually inspect these parts biannually. Check for play in the idler arm, pitman arm, tie rod ends, and ball joints—wear here leads to dangerous handling and destroys tires. Grease every zerks fitting you can find during every oil change. Electrically, the truck's Achilles' heel is not its wiring harnesses, which are generally stout, but its ground connections. Corrosion at the ground points—especially the engine block-to-firewall strap, the battery-to-frame cable, and the ground cluster behind the interior kick panels—causes a multitude of gremlins, from erratic gauge behavior to poor charging and starting.

This simple, cost-free act prevents countless headaches and preserves the integrity of the entire electrical system.
