[Show] Vehicle Maintenance Chapter: Solving abnormal noise in chassis
BessMatthew 
12 Pick up the gauntlet at the end of 2019, which is mainly used for working and commuting, and often goes out for a self-driving trip when taking a rest, so the frequency of vehicles is also very high. When the car has a mileage of more than 2,400 kilometers in more than two years, it is found that the chassis will occasionally creak when the vehicle encounters bumps or ridges. Thinking that the shock absorber plane bearing has been replaced before, there is a good chance that there is something wrong with the chassis suspension. In fact, at the time of the first insurance, the store also fastened the chassis of the frame according to the operating requirements. I don’t know if my self-driving is often driving in irregular road conditions, so here is a simple sharing of my inspection process.
Arrive at the store on time after advance and in-store appointment, and enter the station after checking and registering the appearance of the vehicle.
First of all, he explained and communicated with the master. in view of the fact that the plane bearing had been replaced before, he suspected that there was a high probability that the chassis had screws loose, but he was still responsible for checking the four-wheel suspension of the vehicle and fastening the places where it might be loose one by one.
Lift the vehicle and check the chassis.
Check the four-wheel suspension.
After disassembling the front and rear guard plate of the armour chassis, the front and lower swing arm, the front subframe and the rear torque beam fixing screws were fastened respectively, and finally the problem occurred in these two positions. However, it is not certain whether the first insurance did not screw the fixing screws in place or because the previous self-driving often took the unpaved road bumps and caused loosening, making the relevant connectors have gaps, so they will rub against each other while driving.
Remove the engine lower guard.
Perform a visual inspection of the chassis.
Tighten the relevant parts with screws.
Tighten the relevant parts with screws.
Dedusting
Remove the lower guard plate of the exhaust pipe for visual inspection.
Remove the guard plate, the exhaust pipe has been rusted.
Tighten the screws of the related parts.
Dedusting
Restore the lower guard of the engine
Spray lubricant on related parts
After maintenance, the test drive disappeared, the fault was solved, and the master also affirmed that I could go to the store for inspection in time when I found the problem. In other words, SUV, an entry-level city, could not be built as a hardline cross-country.
In the end: according to the manufacturer’s after-sales policy, Volkswagen models adopt a warranty policy of 3 years or 100000 kilometers, because the vehicle has not been insured so there is no expense in this maintenance. As one of the three major parts of the automobile, the chassis plays the role of carrying vehicle load and installing related components, so it is an indispensable step to carry out relevant inspection during daily maintenance. The purpose of sharing this inspection and repair is also to remind motorists that they need to pay more attention to the condition of the car when they use the car, and that they must deal with anomalies in a timely manner, and remember that the normal condition of the vehicle is the premise to ensure the safe use of the car.
It is said that professional things should be done by professionals, which I have always followed, so when there is something wrong with the car, I am not worried that the maintenance fee is higher than the roadside shop and choose the latter. It is also because as far as I know, regular maintenance engineers in 4s stores are generally specially trained by manufacturers, and they also teach their apprentices by deeds and deeds, so they are more familiar with the models of this brand and are more targeted in judging faults. After all, the masters are qualified. If you need to replace the quality of parts can be relatively guaranteed, and the quality assurance policy after maintenance is more reassuring. This is also the case. According to my description, the master quickly found the problem and solved it with simple fastening. After maintenance, the vehicle has been driving for 11,000 kilometers, and no abnormal noise in the chassis has been found. Here also give praise for the master’s meticulous service, maintenance is not only aimed at solving abnormal noise problems, but also blowing and dedusting the relevant parts of the chassis covered by the protective plate after maintenance, and lubricating the damping system. A week after maintenance, I also made a phone call back and told me that according to the store policy, I could come to the store for free vehicle inspection before and after long-distance self-driving. I think this is the full embodiment of a store’s service consciousness and norms.
