Correct Answer: Option D — Once the bearing cap is properly torqued, measure the end gap dimensions to ascertain even tightening of the cap.

Measuring bearing cap end gaps or fit dimensions post-torquing verifies even clamping force across mating surfaces, preventing localized pinching, distortion, or uneven bearing shell crush during mechanical assembly.
