Understanding the Square Body Steering Column
The square body steering column, integral to GM trucks and SUVs from 1973 to 1987, provides the crucial link between your steering wheel and the front wheels. This mechanism is critical for vehicle control, translating driver input into precise directional changes. While celebrated for their classic appeal and robust build, these columns, like any mechanical component, have specific characteristics that owners should understand for maintenance and potential upgrades.
- Classic aesthetic appeal for 73-87 GM trucks.
- Direct mechanical link to front wheel steering.
- Potential for wear and common operational issues.
- Rebuild kits and remanufactured options exist.
Core Components and Functionality
At its heart, a steering column contains the steering shaft, universal joints (U-joints), and often a tilt mechanism. For the square body era, these columns were typically non-collapsible and featured a robust, albeit basic, design. The steering shaft connects directly to the steering box, which then actuates the tie rods and steering knuckles. Understanding this principle is fundamental to diagnosing any play or binding you might experience. Many owners also seek information on a 64 impala chrome steering column for stylistic upgrades, showing the desire for aesthetic customization.
Common Issues and Diagnosis
The most frequent complaints involve steering wheel play, stiffness, or excessive noise. Wear in the steering box, U-joints, or internal column bushings can lead to looseness. A sticking tilt mechanism or worn ignition switch housing are also common points of failure. If you're experiencing symptoms, inspect the U-joints first, as they are external and accessible. For internal column issues, a remanufactured steering column or a detailed rebuild using a 73 87 chevy steering column rebuild kit is often the most effective solution.

Pros of the Square Body Steering Column
Durability and Simplicity
One of the primary advantages of the square body steering column is its inherent durability. Built during an era where mechanical robustness was paramount, these units are generally simpler than modern electronic power steering systems. This simplicity translates to easier diagnosis and repair for many common issues. The direct mechanical linkage ensures a connected feel to the road, which many enthusiasts prefer over the often-sanitized feedback from newer vehicles. Our analysis indicates this direct feedback is a significant draw for restoration projects.
Aesthetic Integration
For owners restoring or customizing their 73-87 Chevy trucks, the original steering column is an integral part of the classic interior aesthetic. Its design complements the utilitarian yet iconic dashboard. While some may opt for a 1965 mustang steering column or 1966 mustang steering column for a different vintage feel, the square body column is a perfect match for its intended application. The availability of parts like a 64 impala chrome steering column hints at the aftermarket support for enhancing this period-correct look.
It is imperative to acknowledge the value of maintaining period-correct components.
Repairability and Availability
Unlike highly integrated modern systems, the square body steering column is often repairable. Many parts are available, and the mechanics are well-understood by mechanics familiar with classic trucks. This means you can often fix existing issues rather than replacing the entire unit, saving considerable cost. For those seeking a complete refresh, remanufactured steering column options are readily available, offering factory-spec performance at a fraction of the cost of a new, custom unit. This repairability is a major benefit.
Cons and Considerations
Wear and Tear Over Time
The most significant con is age-related wear. Components like bushings, bearings, and the steering shaft itself can wear down over decades of use. This wear manifests as steering wheel play, looseness, or a general feeling of imprecision, compromising handling and safety. A worn steering column can make precise maneuvers difficult and contribute to accelerated tire wear. You must address this promptly.
Inspect your steering U-joints annually for any signs of rust, wear, or excessive play; lubricating or replacing them can prevent more complex column issues down the line.
Lack of Modern Features
Compared to contemporary vehicles, the square body steering column lacks modern conveniences like integrated airbag systems, advanced cruise control buttons, or adjustable steering columns that offer greater tilt and telescopic range. While some aftermarket tilt columns are available, they may not perfectly replicate the original aesthetic or function. If your priority is modern safety and convenience, a stock square body steering column will feel primitive. Understanding this principle is fundamental.
Potential for Costly Rebuilds
While repairable, a full rebuild can be labor-intensive and costly, especially if multiple components are worn. Purchasing a comprehensive 73 87 chevy steering column rebuild kit is essential, but if the main shaft or housing is damaged, the cost can escalate. Sometimes, opting for a reman steering column is more economical than attempting a complex repair on a severely worn unit. The primary consideration involves balancing repair costs against replacement expenses.
The direct feel of a well-maintained square body steering column is a hallmark of classic truck driving, but age demands diligent attention to its internal health.
Steering Column Go Kart Comparisons
While the term 'steering column go kart' might bring to mind simpler, more basic mechanisms, it highlights the fundamental role of the column. However, a square body steering column is a far more complex and robust assembly designed for highway speeds and significant vehicle weight, unlike a go kart steering column which prioritizes lightweight simplicity. This distinction is crucial when evaluating repair needs or aftermarket modifications.
Verdict: Maintaining Your Square Body Steering Column
The square body steering column, despite its age, remains a capable and iconic component for 73-87 GM trucks. Its pros—durability, aesthetic integration, and repairability—outweigh its cons for enthusiasts who value classic truck characteristics. However, it demands regular inspection and timely maintenance to address inevitable wear and tear. Neglecting these issues can compromise safety and driving experience.
For owners facing significant wear, a remanufactured steering column offers a reliable and often cost-effective solution, restoring that crucial connection between driver and road. Understanding the core components and potential problems allows you to make informed decisions, whether you're performing a routine check or planning a full restoration. Such precision is paramount for enjoying your classic vehicle safely.
