[faq]

Does the wheel axle wear only due to frequent moving of the washer?|Not only. Wear is also influenced by unit load, operation on uneven ground, wheel play, and the condition of cooperating components.

Is a bent wheel axle always visible to the naked eye?|Not always. Sometimes the symptom is unstable rolling, uneven play, or difficulty aligning the wheel properly after installation.

What is worth checking together with the axle during repair?|It is good practice to inspect the wheel itself, fastening components, washers, bushings/sleeves, and seating points, because wear of any of these can accelerate axle wear.

Can the wheel axle be selected only by the Therm model name?|This is not the best method. The safest approach is selection by MPN 44820 and comparison of dimensions and mounting method with the removed part.

How can I tell after replacement that the axle was correctly selected and installed?|The wheel should sit firmly without excessive play, rotate correctly, and not cause misalignment or instability when moving the washer.
