VF11 Suspension systems

What would the three tools shown below be used for when removing and refitting suspension components?

• a. Compressing coil spring

• b. Removing / splitting ball joint taper.

• c. Tighten nuts/bolts to correct torque

• d. Aligning the vehicle's wheels

Give one possible effect on the vehicle for each of the following suspension faults.
-Excessive oil leaks from dampers

• Poor road holding and stability     

• Increased fuel efficiency

• Enhanced ride comfort

• Reduced tire wear

State four possible effects of worn suspension dampers

• Increased fuel efficiency

• Wheel hop on acceleration

• Improved steering response

• Reduced braking distance

Name the type of suspension unit shown below and the components A and B

• Macpherson Strut – Coil spring – Damper

• Double Wishbone – Leaf spring – Shock absorber

• Multi-link – Air spring – Strut

• Solid Axle – Coil spring – Stabilizer bar

On examination of a vehicle, it is found that the off side front damper is leaking badly. What recommendation should be made to the customer?

• Change both to ensure balance

• Replace only the leaking damper

• Ignore the issue as it is not critical

• Check the rear dampers for leaks

What task would the equipment shown below be used for after working on suspension components?

• Wheel alignment

• Tracking / toe adjustment

• Brake inspection

• Suspension replacement

14. The setting data for adjusting the rear wheel alignment on a vehicle is 2.9mm toe in + or – 1.2mm. The actual reading from the vehicle when checked is 1.6mm (positive). Is the vehicle within tolerance?

• Yes

• No

• Maybe

• Not sure

What should be done to a new damper before fitting it to a vehicle?

• Prime by hand

• Install without preparation

• Soak in oil

• Test for leaks

State two safety precautions when using a hydraulic jack for work on suspension systems.

• Using the hydraulic jack on an uneven surface

• Ensuring the correct Safe Working Load (SWL)

• Applying the jack to the wrong part of the vehicle

• Using a hydraulic jack without any safety stands

State two functions of a suspension damper

• Reduce spring bounce and ensure good directional stability

• Increase vehicle speed and reduce fuel consumption

• Enhance engine performance and improve aerodynamics

• Lower vehicle weight and increase cargo capacity
