Description

The Dorman wiper arm, part number 42858, holds the wiper blade against the windshield at the front left position and is a direct-fit replacement for the 1984-1988 Toyota 4Runner and 1984-1988 Toyota Pickup. Dorman designed it to fit and work like the original arm on the listed vehicles, and built it for durability and reliable performance.

Direct replacement: Designed to install and work like the original arm on the listed applications.
Restores functionality: A replacement for an original wiper arm that has worn out from spring wear, been damaged by snow, or broken down from metal fatigue.
Durable construction: Made from quality materials for durability and reliable performance.
Trustworthy quality: Backed by Dorman's U.S.-based team of product experts and more than a century of automotive experience.

The wiper arm links the blade to the wiper linkage and uses spring tension to keep the blade pressed against the glass as it sweeps. Signs this part may need replacing include a blade that lifts off the glass or chatters, streaking from weak spring pressure, or an arm that is bent or loose on its mount. If a worn or damaged arm is the cause, this unit replaces it. This listing is for the front left position.
