1480-30 – Center Support Bearing – Volvo Application – 1.772″ ID – 2.375″ Center Bearing To Base

A: No. This is one of the most common fitment mistakes on heavy-duty truck driveshaft rebuilds. The 1480 series uses a larger midshaft stub shaft diameter compared to 1350 -- which is why the 1480-30 has a 1.772-inch inner bore rather than the 1.574-inch bore found on 1350/1410-series CSBs. Forcing a smaller-bore bearing onto the 1480 stub results in an interference fit that cracks the rubber isolator during installation, or a bearing that seizes when pressed onto an undersized stub shaft.

The 2.375-inch center-to-base dimension positions the driveshaft at the designed working angle for Volvo two-piece shaft applications. On heavy trucks, the driveshaft angularity budget is tight -- a center support bearing that sits too high or too low changes the operating angle of both the front and rear joints on the midshaft stub, accelerating needle bearing wear and creating vibration that is often misdiagnosed as wheel balance or tire issues.
