Ididit Swivel Ball Mount: For Custom Setups

Building a custom interior or moving a steering column to a non-factory angle presents unique challenges for mounting. The Ididit Swivel Ball Mount is the premier solution for these complex, non-standard layouts, allowing the column to pass through the dashboard or floorboard at an angle while maintaining a secure, rattle-free fit. Its swivel design absorbs the tension that would otherwise cause binding in a fixed-mount system.

This is the only viable choice for builders who are modifying the ergonomics of their cockpit for better space utilization in a van or tiny home. By providing a secure mounting point that adapts to the specific geometry of a custom build, it prevents the column from vibrating against the dashboard cutout.

How to Know if You Need a Support Collar

Identifying a failing column support is usually straightforward if you know what to look for during a brief inspection. If the steering wheel can be pushed up and down or side-to-side more than a fraction of an inch, the internal bushings or the external support collar are likely worn out. You might also hear audible clicking or tapping sounds when driving over bumps, signaling that the column is striking the mounting bracket.

Pay close attention to any “looseness” felt in the steering wheel when parked; the wheel should remain perfectly centered and stable. If you notice the steering column itself vibrating noticeably while the engine is idling, the mount is failing to dampen the movement of the steering shaft. Ignoring these signs can lead to premature wear on the steering shaft bearings and, in extreme cases, a loss of steering precision while navigating technical terrain.

Measure Twice: Getting the Right Collar Size

The most common mistake during installation is failing to accurately measure the outer diameter (OD) of the steering column. Steering columns are not one-size-fits-all, and even a difference of a few millimeters will result in a sloppy fit that renders the collar useless. Always use a precision set of calipers to measure the exact point on the column where the collar will sit.

Consider the surface finish of the column as well; if it is painted or powder-coated, be aware that the collar needs to fit over the coating without damaging it. Verify the clearance available behind the dashboard panel before ordering to ensure the mount housing doesn’t hit other components like heater vents or wiring looms. Precision in the measurement phase prevents unnecessary returns and ensures a tight, professional-grade fit from the start.

DIY Installation: A Step-by-Step Guide

Begin by safely disconnecting the vehicle battery to avoid any accidental horn engagement or electrical shorts while working under the dash. Remove the trim panels surrounding the column base to expose the original mounting point and the steering shaft. Carefully unbolt the old, worn collar while supporting the steering column from below to prevent it from dropping or putting strain on the steering linkage.

Slide the new collar onto the shaft, ensuring that the alignment is perfect before tightening the set screws or mounting bolts. If using a swivel mount, leave the tension slightly loose until the column is at your desired angle, then lock it down permanently. Finally, test the steering for any binding or unnatural resistance throughout the full range of motion before reattaching your dash trim panels.

Other Causes of a Sloppy Steering Wheel

While a loose support collar is a frequent culprit, it is not the only source of steering play. Worn rag joints—the flexible rubber couplers between the steering column and the steering box—often cause significant steering dead zones. Additionally, inner or outer tie rod ends that have lost their tension will cause the entire steering system to feel disconnected from the road.

Check for play in the steering box itself, as internal gears can wear down over years of heavy use, leading to noticeable “slop” at the center point. Inspect the steering shaft universal joints for signs of rust or seize-up, which can cause erratic steering feel. Addressing the support collar is a vital first step, but always perform a full front-end check to ensure the entire system is operating in harmony.

Ensuring your steering column is properly anchored is a foundational step in maintaining a safe and enjoyable vehicle. By selecting the right collar for your specific steering setup, you eliminate unwanted play and gain a more connected, responsive driving experience. Regular inspection and proactive maintenance of these components will keep your rig performing reliably for years to come.
