Heavy Duty Suspension

Front

Tech A says Leaf springs can be mounted above the axle. Tech B says leaf springs can be mounted under the axle. Who is correct?

Back

Both A and B

Answer explanation

Both Tech A and Tech B are correct. Leaf springs can be mounted above or below the axle, depending on the vehicle design and suspension system requirements.

Front

Who is correct about "underslung" suspensions: Tech A says "underslung" is when the axle is under the springs, and Tech B says "underslung" suspensions have a higher ride height?

Back

Neither A nor B

Answer explanation

Tech A is incorrect because 'underslung' means the axle is below the springs, not under them. Tech B is also incorrect as underslung suspensions typically have a lower ride height, not higher. Therefore, neither is correct.

Front

Tech A says Leaf Spring Suspensions can not work with airbags. Tech B says Leaf Springs are better for heavy duty applications than coil springs. Who is correct?

Back

Tech B

Answer explanation

Tech B is correct because leaf spring suspensions are indeed better suited for heavy-duty applications due to their strength and load-bearing capacity. Tech A is incorrect; leaf springs can work with airbags for added support.

Front

Coil Springs can have dual spring rates. True or False?

Back

True

Answer explanation

True. Coil springs can indeed have dual spring rates, allowing them to provide different levels of resistance depending on the load or compression, which enhances their performance in various applications.

The sudden upward movement caused by a bump:

Back

Jounce

Answer explanation

The term 'jounce' specifically refers to a sudden upward movement, often caused by a bump. While 'jump' and 'rebound' imply movement, they do not capture the specific context of a bump like 'jounce' does.

Front

Which part is unsprung? Options: Cab/Body, Chassis, Wheels, T-Pain, Transmission

Back

Wheels

Answer explanation

The wheels are considered unsprung components because they are not supported by the vehicle's suspension system. Unlike the cab, chassis, and transmission, which are supported, the wheels directly contact the road and bear the vehicle's weight.

Front

Which part is considered Sprung Weight? Options: Axles, Tires, Contact Patch, Engine, Lizzo

Back

Engine

Answer explanation

Sprung weight refers to the weight of components that are supported by the suspension system. The engine is considered sprung weight because it is mounted on the chassis and affects the vehicle's handling and ride quality.

Front

Which one keeps the leaf springs from banging on the frame? Options: Axle Stops, Jounce Blocks, Bushings, Duck Tape

Back

Both Axle Stops and Jounce Blocks

Answer explanation

Both Axle Stops and Jounce Blocks prevent the leaf springs from making contact with the frame during suspension travel, reducing noise and potential damage.

Front

Who is correct regarding leaf springs: Tech A says they do not contact each other due to grease applied at every annual service, while Tech B says contact causes friction that assists in ride dampening?

Back

Tech B

Answer explanation

Tech B is correct. Leaf springs are designed to have some contact, which creates friction that helps in ride dampening. Grease is not typically used to prevent contact but rather to reduce wear.

GMCs Air suspension system is labeled:

Back

Adaptive Suspension

Answer explanation

GMC's air suspension system is referred to as 'Adaptive Suspension' because it adjusts to driving conditions for improved comfort and handling, distinguishing it from other options listed.
