Does replacing bearings affect a new car?
2 Answers
Replacing bearings does not affect a new car. Related introduction of bearings: 1. Function: Bearings are crucial components in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during movement, and ensure rotational accuracy. 2. Lifespan: Due to differences in manufacturing precision and material uniformity, even bearings of the same material and size from the same batch may have varying lifespans under identical working conditions. Taking statistical lifespan as 1 unit, the longest relative lifespan is 4 units, the shortest is 0.1-0.2 units, with a ratio of 20-40 times between the longest and shortest lifespans. 90% of bearings do not experience pitting corrosion, and the number of rotations or hours they endure is called the bearing's rated lifespan.
Replacing bearings on a new car, if done according to specifications and using genuine parts, usually has no negative impact on the vehicle. Bearings are wear-prone components, and there is a minimal chance of assembly issues even in brand-new cars. The key is to find a professional repair shop that uses a torque wrench for standard installation, avoiding forceful disassembly that could damage the axle hub. After replacement, a wheel alignment is necessary to prevent misalignment and uneven tire wear. I've seen many car owners solve the original humming noise by replacing the bearings. However, not replacing them or using inferior bearings may lead to long-term issues like suspension deformation or even half-shaft fractures. Regularly checking tire wear is also crucial, as the condition of the bearings directly affects the tire's contact angle.
