When diagnosing driveline issues, the 1480-70 Center Support Bearing is a critical component to consider, especially in Volvo applications. This bearing features a 1.181″ ID and a center-to-base height of 2.125″, which are essential for maintaining proper alignment and reducing vibration in two-piece driveshafts. If you notice vibrations at highway speeds or hear unusual bearing noise, the center support bearing is often the first suspect. A worn or collapsed rubber isolator can lead to significant driveline vibrations, which can be traced back to this part.
Proper installation is crucial. Ensure that you do not pre-load the rubber isolator during installation, as this can alter the driveshaft’s operating angle. Align the mounting bracket before tightening to avoid unnecessary stress on the bearing. The center-to-center distance of 3.675″ for the mounting holes must also be adhered to for optimal performance.
- Volvo Application
- 1.181″ Bearing ID
- 2.125″ Center Bearing To Base
- 3.675″ Center To Center Of Mount Holes
- Cannot be used on OE shaft; new shafts only for XC70 (04-07) and XC90 (03-05)
By replacing a failing center support bearing with the 1480-70, you restore the driveline’s integrity and ensure a smoother ride. Remember, if you’re experiencing symptoms like vibration or noise, this part is a key player in diagnosing and resolving those issues.
