That said, here's a breakdown of the *possible* causes and why you need a professional:
Possible Causes (requiring professional diagnosis and repair):
* Steering Gear Box: This is the most likely culprit. Excessive play often points to worn-out internal components within the gear box. Repair usually involves a rebuild or replacement of the entire unit – a complex procedure.
* Steering Column: Worn joints or bushings in the steering column can contribute to play. Again, this requires specialized tools and knowledge to diagnose and fix.
* Tie Rod Ends: These connect the steering linkage to the wheels. Worn tie rod ends allow excessive movement and play in the steering. These are relatively easier to replace than the gear box or column, but still require proper alignment after replacement.
* Idler Arm: This is part of the steering linkage. Wear in this part will introduce play.
* Other Linkage Components: Other parts within the steering linkage can wear and contribute to looseness. A thorough inspection is necessary to identify all issues.
Why You Need a Professional:
* Safety: Incorrect repair could lead to a dangerous and potentially fatal situation.
* Specialized Tools: Working on a steering system requires specialized tools and a thorough understanding of the system's mechanics.
* Alignment: After any repairs to the steering system, a wheel alignment is crucial to ensure safe and proper vehicle handling.
Steps to Take:
1. Do not drive the vehicle. The excessive play is a serious safety risk.
2. Have it towed to a qualified mechanic. A reputable mechanic specializing in automotive repair will be able to diagnose the problem accurately and perform the necessary repairs safely.
3. Get multiple estimates if necessary. Compare prices and services offered before committing to a repair shop.
Ignoring this problem is extremely dangerous. Prioritize getting your Suburban to a qualified mechanic as soon as possible.
