Question

The RIST procedure should be performed every time wheels are removed from a vehicle, and it stands for _______________________.

a) Remove wheels - Inflate to specification - Snug in a star pattern - Torque to 450-500 in. lbs.
b) Remove wheels - Install lubrication - Snug in a star pattern - Tighten with impact gun
c) Remove rust, dirt, corrosion from all mating surfaces - Inspect wheel rim and fasteners - Snug in a star pattern - Torque to specification
d) Remove rust, dirt, corrosion from all mating surfaces - Inflate to specification - Snug in a circular pattern - Torque to specification

Answer 1

The correct answer is option c)The RIST procedure is a set of steps to follow when removing wheels from a vehicle, and it stands for Remove rust, dirt, corrosion from all mating surfaces - Inspect wheel rim and fasteners - Snug in a star pattern - Torque to specification.

Step-by-step explanation:

The correct answer is option c) Remove rust, dirt, corrosion from all mating surfaces - Inspect wheel rim and fasteners - Snug in a star pattern - Torque to specification.

The RIST procedure is an important step to follow when removing wheels from a vehicle. It helps ensure proper installation and safety. Here is a breakdown of each step:

1. Remove rust, dirt, corrosion from all mating surfaces: This step involves cleaning off any debris or build-up on both the wheel and the hub to establish a clean surface for proper contact.
2. Inspect wheel rim and fasteners: It is important to visually inspect the wheel rim and the fasteners for any damage or worn-out parts that may affect the installation process.
3. Snug in a star pattern: Snugging the lug nuts in a star pattern helps evenly distribute the load and ensures proper alignment of the wheel with the hub.
4. Torque to specification: Finally, torque the lug nuts to the manufacturer's specifications using a torque wrench to ensure proper tightness and prevent over-tightening or under-tightening.

Following the RIST procedure helps maintain the integrity of the wheel installation, minimizes the risk of accidents caused by loose or improperly installed wheels, and extends the lifespan of the components involved.
