Wheel alignment is an operation that many consider a one-time thing. Do it once and forget about it for the entire service life. An experienced “suspension specialist” will at least smile at this approach. We are ready to explain in detail.
Even in hothouse conditions – on German autobahns and Japanese highways – the suspension is constantly under load. When braking, accelerating, turning. In short, shock absorbers, springs, ball joints, and silent blocks wear out even on ideal asphalt, and this leads to a change in the wheel alignment angles. What can we say about our country, where “environmental aggression” is added to natural forces? And even without mentioning the physical contacts of levers and rods, all elastic, damping and connecting elements wear out much faster here. There is also salt, reagents and the natural ability of metals to “weld” to a state that is difficult to separate. However, more on that later…
Theory of angles
If you don’t dig too deep, in this case, it is simple – familiar and understandable to anyone who has even slightly touched technical literature. Let’s briefly recall the alignment service in Birmingham.
There is no need to know and especially remember the values of the angles for your car, which are in every manual and should be in the programs of services offering wheel alignment. It is unlikely that anyone will do it themselves now, armed with a rope-tape measure and a plumb line or level. Nevertheless, it is necessary to understand that the wear of the “rubber” with the gone angles is only a visible result. From the invisible – worsened controllability due to the smaller contact area of the tires with the road. The steering wheel, tearing out of your hands from the changed shoulder of the rolling – the distance between the axis of rotation of the wheel and the axis of its turn. Finally, unstable behavior on a straight line.
- Sometimes you can observe a very positive collapse.
- Specifically, negative camber is the lot of athletes.
There is another angle, the importance of which is forgotten or belittled – the longitudinal tilt of the axis of rotation: Castor or caster.
Hold the corners!
Well, what do you need to know about wheel alignment angles in practical terms, in relation to operation? Let’s say it again: they go away! And the main culprit here is the silent blocks of the levers. Their rubber deforms over time, the axle gets loose, and the camber angle changes. At the same time, the wheels that have become “house-shaped” also lead toe-in. What’s interesting is that with a small change in the camber angle, the toe-in changes much more significantly. This is the design of the suspension. It turns out like this: the wheels are “house-shaped” just a little, and the tire wear is not necessarily uneven, but strong, since, first of all, it is the knocked toe-in that “eats” the wheels. And only secondly – the wrong camber.
However, in relation to specific models of cars, it is unlikely that a competent mechanic will undertake to say exactly – here it lasts as much, there it is twice as little. Much depends on the quality of the installed spare parts and the driving style. The same applies to the castor, but not everywhere.
There are also a number of models (even brands) with front independent suspensions that do not provide the ability to adjust the camber. The manufacturer implies that with serviceable and undamaged suspension elements, the main angles (camber and caster) will be within the permissible values. These are many Volvos, Mazdas, almost all Audis, BMWs except for the X5, the latest generations of Honda Accord, Ford Focus I and II. The design can be either McPherson or double- or multi-link. What do you need to know in this case? Firstly, the toe-in is adjusted anyway, since natural shrinkage occurs in the silent blocks, and the angles still change. Secondly, if the camber/caster is disturbed, it is already necessary to replace the worn (dented) elements. On the other hand, we also provide cabin filter replacement in Birmingham, the camber tolerances are larger and the angles usually last longer – the manufacturer here, as a rule, lays in a slightly larger margin of safety.
Things to Consider During Wheel Alignment
It would seem that such a solution is a dream for a “camber specialist”: turn the toe-in, and that’s it. And if the camber does not “hit” – please replace the parts for extra money. However, it often happens that the main angles seem to be within the tolerance range, but their combination cannot be called ideal, correction is desirable, despite the fact that adjustment is not provided! How to explain to the car owner that the angles are “in the green zone”, but at the same time, drift to the side and wear of the tires are possible? For example, models from the domestic Japanese market usually require adjustment of the angles for our right-hand traffic. It turns out that the driver is on the right, and the slope of our roads is also to the right. In Japan, these factors compensated each other. If you do not adjust the angles to our conditions, there will certainly be a right-hand drift of the car and uneven wear of the wheels. When camber/caster adjustment is provided – there are no problems. Adjusted, and the soul is at peace, not ashamed to look the person in the eyes in six months. But when there is nothing to adjust? Therefore, in my opinion, it is better if adjustment is provided, especially when operating in our conditions.
How do you choose a service?
I suggest the following option: ask by phone whether they will do a Niva, a second-generation Mitsubishi Pajero or a first-generation Nissan Terrano? If yes, then you can safely go with any other car.
Conclusion
Understanding the significance of angles such as camber and caster is crucial for maintaining your vehicle’s performance and safety. Even if your car’s alignment falls within manufacturer tolerances, adjustments may still be necessary to account for local road conditions and driving habits.
When selecting a service for wheel alignment, ensure they have experience with your specific vehicle model and understand the nuances of the local driving environment. With proper maintenance and timely adjustments, you can ensure a smoother ride, improved handling, and longer-lasting tires, ultimately enhancing your driving experience in Birmingham.
