Is it easy to repair a car with bearing seizure?

[Emmett]

Repairing a car with bearing seizure is quite challenging and requires professional expertise. Here's an introduction to automotive bearing seizure: 1. Overview: As the name suggests, the car's bearing fails and seizes the shaft. 2. Causes: (1) Poor quality of crankshaft or bearings. Especially for vehicles that have undergone major repairs with bearing replacements, if the shaft grinding and bearing scraping work wasn't precise enough. (2) Poor surface finish between the journal and bearing. (3) Improper fit between shaft and bearing after installation. If the contact area is too small to form an oil film, plus with clearance behind the bearing, the alloy and bearing can't fully adhere tightly, leading to loosening and outward movement, blocking oil holes and causing oil supply interruption resulting in dry friction.
