Gunson Trakrite: A Mobile Mechanic's Revelation

In the fast-paced world of automotive mechanics, where cutting-edge laser technology and digital diagnostics reign supreme, it's easy to dismiss older, seemingly rudimentary tools as relics of a bygone era. We're often conditioned to believe that precision can only be achieved through complex, high-tech solutions. However, sometimes, a return to basics reveals an unexpected level of efficacy, challenging our preconceived notions. This was precisely my experience with a particular piece of kit from Gunson Tools, a brand synonymous with straightforward, practical solutions for the home mechanic and professional alike.

My journey to becoming a firm believer in the Gunson Trakrite, specifically their toe alignment gauge, began with a healthy dose of skepticism. I'd seen my grandfather use one of these in his workshop years ago, and with the advent of sophisticated laser alignment systems, I genuinely thought such a basic device couldn't possibly offer any meaningful accuracy. How could a simple rolling plate, devoid of digital readouts or laser beams, stand up to the demands of modern vehicle maintenance? I was about to find out, quite by accident, just how wrong I was.

Who Are Gunson Tools? A Legacy of Practicality

Gunson Tools, part of the Draper Tools Group, has carved out a niche for itself by producing innovative yet affordable tools primarily aimed at the DIY enthusiast, but often finding their way into professional workshops due to their sheer practicality. Founded in 1946, they've built a reputation for clever, problem-solving devices that simplify complex tasks. Their philosophy seems to be about providing effective solutions without unnecessary complexity or exorbitant cost. The Gunson Trakrite wheel alignment gauge is perhaps one of their most iconic examples, embodying this ethos perfectly. It's a tool that relies on fundamental physics rather than complex electronics, offering a refreshingly simple approach to an often-overlooked aspect of vehicle maintenance.

The Skeptic's Conversion: From "Cr@p DIY" to "Spot On!"

The moment of truth arrived late one evening. My own van needed a repair, and with no time for a professional alignment, I was in a bind. I had a considerable distance to drive over the next three days, and the thought of uneven tyre wear or poor handling was unsettling. As I rummaged for a tape measure, hoping to at least 'rough set' the toe, my mate chimed in, suggesting I use his Gunson Trakrite. My immediate reaction was a dismissive chuckle: "Haha, that cr@p DIY thing? Well, I guess it can't make it any worse!" Little did I know, those words would soon be eaten.

Following the straightforward guide, I positioned the Trakrite and dialed the toe to zero. It was surprisingly easy to achieve a consistent reading. I then drove the van a short distance, centered the steering wheel with equal adjustments to the track rods, and rechecked/fine-tuned the toe. The process was intuitive, and I found it surprisingly simple to obtain a constant zero scrub reading. I drove away, thinking it was probably "good enough" for my immediate journeys, but fully intending to get a proper laser alignment as soon as possible.

A delay the following morning unexpectedly granted me the opportunity to get the van onto a ramp. With a mix of trepidation and curiosity, I awaited the verdict. What transpired next left me absolutely gobsmacked. The laser alignment machine confirmed it: no spanner required, the toe was spot on! It was within professional tolerances, a result I never thought possible with such a basic tool. This single experience completely shattered my preconceived notions about accuracy and simplicity.

The Mechanics of Simplicity: How the Trakrite Works

The Gunson Trakrite operates on a deceptively simple principle. It's essentially a rolling plate with a gauge that measures the side-slip or 'scrub' of the tyres as the vehicle is slowly driven over it. When a wheel has incorrect toe, it isn't rolling perfectly straight; instead, it's constantly scrubbing sideways across the road surface. The Trakrite's internal mechanism detects this lateral movement and translates it into a reading on a dial, indicating whether the toe is in, out, or neutral (zero scrub).

Unlike laser systems that measure angles directly, the Trakrite measures the *effect* of those angles on the tyre's contact patch. For toe adjustment, which is often the only adjustable parameter on many modern vehicles, this method proves remarkably effective. It's a testament to the idea that sometimes, directly measuring the symptom (tyre scrub) is just as, if not more, practical than measuring the cause (wheel angle) with complex equipment, especially when considering real-world driving conditions.

Accuracy vs. Complexity: Why Simple Can Be Superior

While a full laser alignment system offers comprehensive measurements for toe, camber, and caster, and provides precise digital readouts, their accuracy is ultimately dependent on the operator. As the saying goes, "any kit is only as good as its operator." I've seen firsthand how an expensive laser system can have its accuracy negated by a hurried technician resting the sensor on a balancing weight, or worse, selecting the wrong vehicle model from the database. These errors can lead to alignments that are worse than doing nothing at all, despite the high-tech equipment.

The Gunson Trakrite, by contrast, is far less susceptible to such fundamental operator errors when it comes to toe. Its direct measurement of tyre scrub provides an intuitive feedback loop. If the needle isn't at zero, you adjust until it is. There's no complex software to navigate, no databases to mis-select, just a clear indication of whether your tyres are scrubbing or rolling freely. For a mobile mechanic, or even a home enthusiast, this simplicity translates to reliable results that are consistently within tolerance for the vast majority of cars and vans.

The Mobile Mechanic's Indispensable Ally

My Gunson Trakrite now has a permanent home in the back of my mobile van. It has become an essential piece of my toolkit. After performing a suspension repair – replacing track rod ends, steering racks, or control arms – setting the toe is crucial. Many customers, understandably, are reluctant to add the cost of a full garage alignment to an already expensive repair. This is where the Trakrite shines. It allows me to perform a rapid, accurate toe adjustment on-site, ensuring that the customer's front tyres aren't destroyed within a few miles due to severe misalignment.

It provides peace of mind, both for me and for the customer. I can confidently leave a job knowing that the vehicle is at least running with correct toe, preventing premature tyre wear and ensuring safe handling until they can, if they choose, get a more comprehensive alignment check. It's a fantastic value proposition, offering a professional touch without the professional price tag.

Maximising Your Gunson Trakrite's Potential

While the Trakrite is incredibly simple to use, a couple of small tips can ensure you get the most consistent results:

1. Clear the Path: Before rolling the vehicle over the Trakrite, always give the area a quick sweep. Small stones or gravel can interfere with the plate's smooth movement and lead to inaccurate readings. A simple brush is all you need.
2. Even Surface: Ensure the ground where you're using the Trakrite is as level as possible. Significant slopes can affect the readings.
3. Slow and Steady: Drive the vehicle very slowly and smoothly over the plate. Jerky movements can skew the results.
4. Consistent Technique: For repeatable results, try to be consistent with how you drive over the Trakrite each time you take a reading.

In conclusion, the Gunson Trakrite is a surprisingly good bit of kit. It's a humble, low-tech solution that consistently delivers high-quality results for toe alignment. It proved to me that sometimes, the simplest tools, when well-engineered and understood, can outperform even the most sophisticated equipment, especially when human error is factored into the equation. For any mobile mechanic, or indeed any car owner keen on saving their tyres and improving their vehicle's handling, this tool is an absolute revelation.

Frequently Asked Questions About Wheel Alignment and the Gunson Trakrite

Is the Gunson Trakrite accurate enough for professional use?

Based on my experience and comparison with professional laser alignment equipment, the Gunson Trakrite provides accuracy for toe adjustment that is consistently within tolerance for the vast majority of vehicles. While it doesn't offer the comprehensive data of a full laser system, for simply setting toe, it is remarkably effective and reliable for professional mobile mechanics and workshops.

Can the Gunson Trakrite measure camber or caster?

No, the Gunson Trakrite is specifically designed to measure toe (or 'tracking') by detecting tyre scrub. It does not measure camber (the inward or outward tilt of the wheel) or caster (the angle of the steering axis). For these measurements, a more comprehensive alignment system is required.

How often should I check my vehicle's wheel alignment?

It's generally recommended to have your wheel alignment checked annually or every 10,000-12,000 miles, whichever comes first. However, it's crucial to check alignment after any significant suspension or steering component replacement (e.g., track rod ends, ball joints, shock absorbers), after hitting a large pothole or kerb, or if you notice uneven tyre wear or steering issues.

What are the common signs of bad wheel alignment?

Key indicators of poor alignment include uneven or premature tyre wear (especially on the inner or outer edges), the vehicle pulling to one side when driving straight, a crooked steering wheel when driving straight, or a loose or vague feeling in the steering.

Is the Gunson Trakrite difficult for a DIY mechanic to use?

Not at all. The Gunson Trakrite is renowned for its simplicity. It comes with clear instructions, and the process of driving over it and reading the dial is very straightforward. With a little practice, even a novice can achieve accurate toe settings, making it an excellent investment for home mechanics.
