1984-1985 Toyota 4Runner Steering Column: Fixing Play and Finding the Right Part
This guide covers the common failure points, compatibility issues, and inspection tips for the first-generation 4Runner steering column.
- Compatibility is critical: You must match your new column to your vehicle's exact setup (Power/Manual steering and Tilt/Non-Tilt wheel).
- Excessive steering play is the most common failure, often caused by a worn internal slip joint that can sometimes be fixed with DIY methods.
- Before buying a used column, physically inspect it for shaft play, U-joint condition, and smooth bearing operation.
- New OEM columns are mostly discontinued and aftermarket options are unavailable, making a quality used OEM part the best choice.
Critical Compatibility Warnings for 1984-1985 4Runner
Before purchasing a steering column, you must correctly identify your vehicle's configuration. Ordering the wrong part is the most common mistake. There are four primary variations for this generation:
- Power Steering with Tilt Wheel: For models equipped with both factory power steering and an adjustable tilting column.
- Manual Steering with Tilt Wheel: For models with a non-powered steering box but an adjustable tilting column.
- Power Steering with Non-Tilt Wheel: For models with power steering but a fixed, non-adjustable column.
- Manual Steering with Non-Tilt Wheel: The base model configuration with no power steering and a fixed column.
Warning: The 1984-1985 4Runner and Pickup use a specific non-collapsible column design. Columns from 1986 and later models are often collapsible for safety and will not fit correctly. Always verify the part is from an '84 or '85 model.
Symptoms of a Failing Steering Column
A worn steering column can introduce a range of issues from annoying noises to serious safety concerns.
1. Excessive Steering Wheel Play or Looseness
This is the most common complaint for these vehicles. You'll notice the steering wheel can be moved back and forth without the front wheels turning immediately. This looseness often originates from a worn plastic ball joint inside the tilt mechanism or a worn slip joint on the main shaft. While a small amount of play is normal on older vehicles, excessive movement makes the truck feel unstable and wander on the highway.
2. Grinding, Clicking, or Popping Noises
Audible noises when turning the wheel often point to failing components within the column. A grinding or squeaking sound can indicate a dry or worn-out upper or lower column bearing. A clicking or popping sound, especially when initiating a turn, can be caused by a worn universal joint on the intermediate shaft or loose internal parts.
3. Tilt Mechanism Failure
On models with a tilt wheel, the mechanism that locks the column in place can fail. The steering wheel may not lock into position, or it might slip from its set position while driving. This is often caused by wear in the locking pawls or the tilt lever assembly.
4. Stiff or Binding Steering
If the steering feels unusually stiff or binds at certain points in its rotation, it could be caused by a failing U-joint on the intermediate shaft or a seized bearing inside the column. This can be a serious safety issue as it can make it difficult to steer the vehicle precisely.
Known Issues for 1984-1985 4Runner
While no formal recalls or TSBs exist specifically for the 1984-1985 steering column itself, the community has well-documented a common problem:
- Worn Internal Slip/Ball Joint: The most frequent source of steering "slop" or play is wear within the column's own joints. Forum users have developed common DIY fixes for this, such as disassembling the column and shimming the plastic ball joint with a thin piece of plastic to tighten the tolerance, or placing a small tack weld on the slip joint to eliminate play entirely.
Pro Tip: Before blaming the steering column for play, have a helper rock the steering wheel while you inspect the entire system. Check for movement at the intermediate shaft U-joint, the connection to the steering gearbox, the pitman arm, and the tie rod ends. Play in these other components is also common and can mimic a bad column.
Buying a Used Steering Column: Inspection Guide
Since new OEM columns are largely discontinued and quality aftermarket replacements are unavailable, a used OEM column is the best option. Here’s what to check before you buy.
- Verify the Exact Configuration: This is the most important step. Does it have a tilt lever? Is it from a power or manual steering truck? Compare photos of the mounting points and shaft connections to your original column.
- Check for Shaft Play: With the column on a bench, hold the lower shaft steady and try to rotate the upper shaft where the steering wheel mounts. Any significant rotational play indicates wear in the internal slip joint.
- Inspect the Intermediate Shaft U-Joint: The universal joint on the lower shaft is a critical wear item. It should move smoothly in all directions without any binding, notchiness, or looseness. Rust and stiffness are red flags.
- Test the Bearings: Try to wiggle the shaft from side-to-side within the column tube. Significant side-to-side movement points to worn upper or lower bearings. Spin the shaft; it should rotate smoothly without grinding noises.
- Check the Tilt Mechanism (if applicable): Operate the tilt lever. It should engage firmly and the column should lock securely in each position without slipping.
- Inspect Electrical Components: Ensure the turn signal and wiper stalks are present and physically intact. Check that the wiring harnesses and connectors are not cut, cracked, or damaged. Replacing these can be an added expense.
Replacement Overview and Difficulty
Replacing the steering column is a moderately difficult job that a skilled DIY mechanic can perform. The main challenges are working in a tight space and ensuring the steering wheel is reinstalled correctly.
- Difficulty: 3 out of 5
- Estimated Time: 2-3 hours
- Process: The general steps include disconnecting the battery, removing the steering wheel and plastic column covers, unplugging all electrical connectors, removing the bolts securing the column to the dash support, unbolting the intermediate shaft from the steering gearbox at the firewall, and carefully removing the assembly from the vehicle.
Cost Comparison
This table provides an estimated cost breakdown for replacing a 1984-1985 4Runner steering column.
| Part Type | Estimated Cost | Notes |
|---|---|---|
| New OEM | $300 - $500+ (for individual shafts) | Complete assemblies are discontinued. Individual shafts and bearings may be available but are very expensive. |
| New Aftermarket | Not Available | Complete aftermarket columns for this specific vintage are generally not produced. |

Frequently Asked Questions (FAQ)
How can I tell if I have a tilt or non-tilt steering column?
A tilt column will have a distinct lever on the side (usually the left) that you pull or push to adjust the steering wheel's angle up and down. A non-tilt, or fixed, column will have no such lever.
Can I swap a power steering column into a manual steering truck?
While the columns may physically bolt in, the shafts are often different lengths and have different spline counts where they connect to the steering gearbox. It is not a direct swap and should only be attempted as part of a complete power steering conversion. It is always best to match the column to your vehicle's original steering type.
Is a loose steering wheel always the column's fault?
No. Steering play can also be caused by worn tie rod ends, a worn pitman arm, a loose steering gearbox, or worn wheel bearings. It is essential to inspect the entire steering and suspension system to correctly diagnose the source of the looseness before replacing parts.
Was there a recall on the 1984-1985 4Runner steering?
There were no recalls for the steering column itself on 1984-1985 models. However, a major safety campaign (SSC 50N) was issued for the steering *relay rod* on later models (1990-1995 4Runners), which could fracture and cause a complete loss of steering control. While this doesn't apply to the '84-'85 models, it highlights the importance of inspecting all steering linkage components.
