Steering Column - Tilt Toyota 4Runner I

DESCRIPTION

Tilt steering wheels incorporate an upper steering shaft, attached by a universal joint, with an intermediate steering shaft. These shafts are held in place by upper and lower brackets.

Brackets are pinned together so upper bracket can move up or down. Upper bracket is locked in place by pawl attached to lever. Steering columns are collapsible.

Some models of Cressida and Supra use a Progressive Power Steering (PPS) system and/or a Toyota Electronically Modulated Suspension (TEMS). the steering sensor for either system is located under the steering column near the break-away bracket.

Note. For models without tilt wheel steering columns, see STEERING COLUMN - FIXED article in this section.
