1280-70 is a Center Support Bearing specifically engineered for Infiniti applications, particularly the Q45 models from 1990 to 1996. This bearing features a 1.181″ ID, which is critical for maintaining the proper fit and alignment of a two-piece driveshaft. The center bearing to base dimension of 1.125″ is designed to ensure that the driveshaft operates at the correct angle, preventing unnecessary wear and tear on the driveline components.
One of the key roles of the 1280-70 is to support the driveshaft at its midpoint, which helps to reduce whip and maintain alignment under load. If the rubber isolator within the bearing deteriorates or collapses, it can lead to increased vibration, especially at highway speeds. Symptoms of failure may include noticeable driveline noise and vibrations that can compromise vehicle performance.
- 1.181″ Bearing ID for optimal fit
- 1.125″ Center Bearing To Base for correct alignment
- 6.000″ Center To Center Of Mount Holes for secure installation
- Designed for Infiniti Q45 (90-96) applications

When installing the 1280-70, align the mounting bracket before tightening to avoid pre-loading the rubber isolator. This attention to detail will help maintain the integrity of the driveline system and ensure smooth operation. Trust the 1280-70 Center Support Bearing for reliable performance in your Infiniti.
