The performance of shock absorbers declines steadily over time. These subtle changes are difficult to detect since drivers adapt to them over time. The first warning can be when a road incident results in loss of control of the vehicle, often with dire results.
Tomson Motors uses the latest in German precision engineering, the Beissbarth shock tester. We are the only workshop in the Western Cape with this technology, which allows us to quickly and cost effectively test and detect any problems with your vehicle's shocks. The device generates a detailed and accurate report of your shocks’ current condition - providing safety thresholds for road grip and resonance frequency - allowing you to make an informed decision.
It is advisable to check a vehicle’s shocks at least every 20 000 km. After 70 000 km this becomes an absolute necessity. Shocks can only be accurately assessed using sophisticated equipment. Traditional manual or 'quick' tests which are commonly used do not give accurate results. It is impossible to 'see' faulty shocks. Generally shocks are not tested during routine services, as most service centres do not have the necessary equipment.
Shock absorbers are designed to keep the tyres in contact with the road. They essentially prevent tyres bouncing. This is essential since without this consistent and firm tyre to road contact it is impossible to have complete control over a vehicle.
Dangers of worn shock absorbers
1. Poor road holding – tyres are not in contact with the road surface to provide adequate control.
2. Tyre wear – damaged or worn shocks cause bald sorts?? areas? and dramatically reduce tyre life.
3. Poor braking – worn shocks cannot prevent tyres bouncing. This results in tyres not being in firm contact with the road during braking.
