In a transmission that has been taken apart, all bearings are excessively worn. Which statements are correct?

• A. Technician A only
• B. Technician B only
• C. Both A and B
• D. Neither A or B

Answer: (C)

When bearings in a transmission are found to be excessively worn after taking it apart, replacing them all is the prudent course because partial replacement can leave mismatched clearances and uneven loading that quickly cause new failures. Replacing every bearing ensures uniform support and predictable operation.

At the same time, this situation warrants a careful check of related components—shafts, gear races, and mating surfaces—for wear or damage. If any of those parts show out-of-tolerance conditions, they should be replaced too to maintain proper fit, clearance, and lubrication.

So, if one statement says to replace all bearings and the other says to inspect and replace worn related parts as needed, both are describing necessary steps. Taken together, they reflect the appropriate approach, which is to restore the transmission to good working condition by replacing worn bearings and addressing any accompanying wear on nearby parts.
