MOT test of Suspension

MOT car includes a complete check-up to ensure that the car is worthy and safe to be on the state's roads. This MOT testing includes verification of various parts ranging from car tyres to the working of the steering wheel. MOT tester visually examines multiple factors of the car and pass or fail the vehicle.

One primary system connected to the steering wheel is the suspension system. It includes parts of suspension systems like cover springs, coil and leaf springs, shock absorbers, suspension arms, joints, etc. The verification procedure for all these parts is shown in detail by the MOT academy.

Detailed attention will be given to the top and bottom suspension mountings during this examination. All of these parts will be checked for signs of wear and tear, corrosion, or any signs of damage. Every MOT testing guide knows the procedure to be followed during the examination, and during the practical training sessions, they transfer the same knowledge to the candidates.

Points to note during the verification of each part are:

• No split pins or nuts are missing from the system.

• No system component visible below the bonnet is cracked, broken or severely damaged.

• All suspension joints are in optimum condition.

• Road springs are working in the usual manner.

• There is no leak in the shock absorbers, and they are entirely secured.

Every MOT academy during the practical training arranges to provide a visual examination demo of the suspension system. During this demo, what and how the parts are examined is demonstrated in detail.

1. Suspension springs:

This part of the examination is about checking the condition of bonded suspension units. The MOT tester looks for attachment of the leaf or coilspring to the chassis. If the points are mismatched, the vehicle is failed.

1. Shock Absorbers:

This is one crucial part to verify during the verification process. The MOT testing guide knows the machine's standard position of the shock absorbers. During the trainitions are appropriatechniques to verify them. All the points are perfectly attached to the chassisng is missing or damaged.

In some cases, a shock absorber seems to be missing from the model, but it is accepted only where such fitting is the standard fitting of the shock absorber systems in the cars.

1. Suspension rods, bars, frames and anti-roll balls:

This is a structure of steel or metal pressings used in the vehicle from the bottom. Verifying these components is necessary as they collect dirt, salt, or other deteriorating factors from the roads. The verifier looks for welded parts or major repairs of the elements. Also, highly stressed bars or heated components are taken as dangerous for road journeys.

1. Suspension joints, pins and bushes:

Rubber and synthetic bushes are not accepted when it looks like they have worn down. Some are built with strength to work with better movements. Their measurements are checked with a small pinch bar or wheel play detector. Verification points are more than 2mm wear for a 12-diameter pin, 3mm for a 25mm diameter pin, and 10% of diameter mm.

1. Gas, air and fluid suspension:

During verification of this, you should be aware of the cautious measures to be taken by the tester.

Wrapping Up:

The suspension system is one of the critical parts of the car that helps save passengers from bumps. This system needs to be in optimum condition to travel hassle-free. MOT experts understand the positions and ensure that the vehicle passes the minimum expectation bars.
