1. Steering Linkage:
* Tie Rod Ends: These are common wear points. Check for play by grabbing each tie rod end and trying to move it up and down and side to side. Any noticeable movement indicates worn ends needing replacement.
* Idler Arm: Located on the frame, this connects the steering linkage to the pitman arm. Excessive play here indicates a worn idler arm bushing or the arm itself needs replacement.
* Pitman Arm: This connects the steering box to the linkage. Check for play at the pitman arm where it connects to the steering box.
* Center Link: Connects the tie rod ends. Look for play in the center link.
2. Steering Gear Box:
* Steering Box itself: Internal wear within the steering gear box can cause slop. This is usually diagnosed by checking for play in the steering wheel while the vehicle is stationary (with the engine off). Excessive play here usually means a rebuild or replacement of the steering gear box.
3. Suspension Components:
* Ball Joints: Worn ball joints in the upper and lower control arms can contribute to steering slop. Check for play by jacking up each wheel and checking for movement in the ball joint. Listen for any "clunking" sounds.
* Bushings: Worn control arm bushings, shock bushings, or other suspension bushings can allow excessive movement which would affect steering.
4. Other Possibilities:
* Power Steering Fluid: Low power steering fluid can exacerbate slop, though it wouldn't be the root cause. Check the fluid level and top it off if necessary. Also check for leaks.
* Power Steering Pump: A failing power steering pump might not provide enough assistance, leading to a feeling of slop.
Troubleshooting Steps:
1. Visual Inspection: Carefully inspect the entire steering linkage and suspension for any obvious damage, wear, or loose components.
2. Check for Play: Manually check each component (tie rod ends, idler arm, pitman arm, ball joints) for excessive play.
3. Steering Wheel Play: With the vehicle off, sit in the driver's seat and grab the steering wheel. Check for play (any movement before the steering wheel begins to turn the wheels).
4. Test Drive: Take a test drive and pay attention to any unusual noises or vibrations.
If you're not comfortable doing this yourself: Take your Bronco II to a qualified mechanic. Diagnosing and repairing steering issues requires proper tools and safety precautions. A faulty steering system can be dangerous.
