4 how should you check for play in the wheel bearing?
whether the wheel is supported or not supported, it has no influence on the measurability of wheel bearing play.
when the wheel hangs freely.
when the wheel is supported.

Explanation:

To determine the correct way to check for play in a wheel bearing, we analyze the options:

• The first option is incorrect because the wheel’s support (or lack thereof) does influence the measurability of wheel bearing play. For example, a supported wheel (e.g., on the ground) or a freely hanging wheel (e.g., on a lift) changes how forces act on the bearing, affecting play detection.
• The second option (“When the wheel hangs freely”) is correct. A freely hanging wheel (e.g., when the vehicle is lifted) allows gravity and manual force to reveal bearing play more clearly, as the wheel is not under the weight of the vehicle.
• The third option (“When the wheel is supported”) is also correct. A supported wheel (e.g., on the ground) can be checked by rocking the wheel (top to bottom, side to side) to feel for excessive play, as the vehicle’s weight loads the bearing, making play more apparent in some cases.

However, the first option is a distractor (it is factually wrong). The correct methods to check wheel bearing play are when the wheel hangs freely (to assess radial play without load) and when the wheel is supported (to assess play under the vehicle’s weight, e.g., by rocking the wheel). If forced to choose the most accurate single answer (or the key method), checking when the wheel hangs freely is a standard technique (as supporting the vehicle to let the wheel hang removes the vehicle’s weight, isolating bearing play).

Answer:

When the wheel hangs freely. (And "When the wheel is supported" is also a valid method, but the first option is incorrect.)

(Note: If the question expects selecting the correct option(s), the valid ones are "When the wheel hangs freely" and "When the wheel is supported"—the first option is incorrect.)
