DESCRIPTION
The steering system is a collapsible, 2-piece upper-lower column shaft, joined by a bellows-type section. The bellows section contracts axially under impact without affecting shaft turning motion.
| CAUTION | To provide increased occupant protection, the energy absorbing steering column is designed to be collapsible upon frontal impact. Applying excessive pressure, or causing impact to mainshaft during service, may cause the column to collapse. |
Scheme 1
- Remove steering wheel. Remove steering column cover. Pull out column switch connectors. Pull switch out toward steering wheel end. NOTE: When removing steering column as an assembly, leave all joining clamps intact.
- On vehicles without tilt steering, remove steering shaft upper coupling bolt. Remove bolts retaining steering column brackets to frame. Disconnect steering shaft from coupling inside vehicle. Remove steering column assembly.
- On vehicles with tilt steering, lower steering column assembly toward floor by removing lower bracket and tilt bracket bolts. Remove bolt which holds steering shaft to joint assembly. Remove steering column assembly.
- Remove intermediate shaft lower coupling bolt at steering gear. Remove dust cover retaining bolts. Remove intermediate shaft, with dust cover, toward inside of vehicle.
Scheme 2
- Install dust cover to intermediate shaft. Ensure bearing side of cover faces steering shaft side of intermediate shaft.
- Apply grease to bearing and dust cover. Install 2-piece bearing into dust cover. Attach intermediate shaft lower joint to steering gear and temporarily tighten dust cover bolts. Tighten lower joint clamp bolt.
- Connect intermediate shaft upper joint to steering shaft. Attach steering column brackets to dash. Tighten clamp bolt of intermediate shaft and column bracket bolts.
- Loosen dust cover bolts and position dust cover so no clearance exists between joint and dust cover sliding surfaces. Tighten dust cover bolts. Adjust steering wheel position if necessary.
Disassembly
- Remove the 2-piece bearing from dust cover of intermediate shaft. Remove dust cover from intermediate shaft.
- Remove snap ring from steering wheel end of steering shaft. Using ignition key, unlock steering wheel lock. Remove steering shaft from column by lightly tapping shaft with soft mallet.
- If steering lock is to be removed, cut a slot in retaining screws with hacksaw. Use a flat blade screwdriver to remove screws. Remove steering lock. Always use new screws and bracket when replacing steering lock.
- If steering column bracket is removed, cut a slot in retaining bolt with hacksaw. Remove bolts with flat blade screwdriver. Always use new bolts when installing bracket to steering column.
Inspection
- Check steering shaft for runout and length. Runout should be .02" (.5 mm) or less, length should be 21.89" (556.2 mm). Check for worn or damaged bearings.
- On intermediate shaft, check for play, noise or rough rotation in joints. Also check for damaged dust cover. Replace components as required.
Scheme 3
Assembly
- Install steering shaft in steering column and install snap ring. Install and tighten column tube bracket shear bolt until head snaps off.
- Fill bearing with grease and install in end of steering column. Ensure bearing is fully seated. Align steering lock with column boss. Use ignition key to check for proper lock function. Tighten lock retaining screw.
Note. Steering lock retaining screws are special 1-way design.
