Steering Column - Tilt Toyota Tercel L30

Steering Column 6 illustrations ~2255 words

DESCRIPTION

Tilt steering wheels incorporate an upper steering shaft, attached by a "U" 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 Cressida and Supra models 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.

Removal

  1. Disconnect battery ground cable. Remove steering wheel. On Cressida, FWD Corolla, MR2 and Tercel models, remove fuse box cover, lower instrument trim panel and air duct from under steering column.
  2. On all models, remove upper and lower steering column covers. Remove combination switch. Mark position of "U" joints and shaft for reassembly.
  3. On models with "U" joints, remove "U" joint retaining bolt. On models with flexible joint, remove flexible joint retaining bolt. NOTE: On 2WD Pickup models, remove steering column with intermediate shaft attached.
  4. On all models, mark position of joint and pinion shaft for reassembly. Remove intermediate steering shaft.
  5. Remove floor pan cover bolts. Remove tilt bracket-to-dashboard mounting bolts. Remove steering column toward inside of vehicle.
