There are two repair shops. One needs only 6 yuan for four-wheel alignment, and the other needs 18 yuan. Which one will you choose?
some repair shops can do it in 2 minutes, while others need an hour or more. what's the difference?
Just like today, this customer will definitely not come next time. Alas, it is difficult to do things.
A four-wheel locator and a four-column lift need at least 6W, and the input and output are not proportional, but there is no way. Now the competition is too fierce. There are 6/7 repair shops within 5 kilometers of Fiona Fang in each community here, and the fees are high this time, so we will go to another one next time. Anyway, there are plenty of repair shops.
when the owner came to our store to replace the right rear wheel bearing, the master found that the two rear wheels ate tires, that is, the left and right wear of the tread was different. The blue wear is normal, and the red circle is badly worn.
the owner said, let's do a four-wheel alignment. It takes two hours to make sure that there is no problem to deliver the car. Finally, the customer said that the working hours are too expensive, and others are 5/5 in 6 yuan. Why did we ask him to accept 18 yuan?
at one time, the owner was very angry and said that we were too dark. He explained it for half an hour, and told the owners who didn't understand the car about maintenance. To put it bluntly, they were casting pearls before swine. They didn't care how long your maintenance process took, but only cared about the price. The owner finally gave the money reluctantly, and I don't think he will come next time.
The data of the camber angle of the rear wheel is quite different
Actually, we can accept it if the owner doesn't understand it, because usually people just adjust the "toe-in" of the front wheel, and the tie rod is loose and tight, which can be fixed in 2 minutes, so the price in 6 yuan is reasonable. If the "camber angle" or "caster angle" of the front wheel is adjusted and eccentric bolts are installed, the adjustment is not troublesome, and it can be fixed in one hour.
and the most troublesome thing is to adjust the "toe-in" or "camber" of the rear wheel. For vehicles with non-independent rear axle suspension, the positioning data can't be adjusted, because the rear axle is deformed as a whole. There are two solutions, one is to replace the whole rear axle, and the other is to add gaskets like this car today.
the gasket of this car is installed on it, that is, the tire is arranged in the shape of an inner figure (installed in the front or rear is to adjust the toe-in)
The price of the rear axle is not cheap. If you don't want to replace the rear axle, you can only add a gasket between the hub bearing and the rear axle. According to the data of camber and toe-in, install the gasket up, down or front and back, and then check the positioning data. Repeat this for many times to find the gasket with the most suitable thickness. So the workload is very heavy, and the expenses in 18 yuan are really not high.
I'd like to take this opportunity to talk about the reasons for eating tires, which can be divided into two types:
One is that the tire tread is flat although the wear on both sides of the tire is different, which is usually a problem with the camber data of the tire.
the other is that the tread is jagged, which usually means that there is something wrong with the toe-in.
