SKF Drive Shaft Center Support Bearing P/N:HB1720-10
SKF HB1850-10 rear drive shaft center support bearing for the 2001-2017 Toyota Highlander and other vehicles supports the drive shaft at its midpoint. It is built to OE-level specifications.
Vibration or a hum from the middle of the vehicle that changes with road speed can mean this bearing is worn, though a worn universal joint or a drive shaft that is out of balance can be behind it too, so find the actual cause before you replace anything.
This bearing fits the 2001-2017 Toyota Highlander, the 2003-2017 Toyota Sienna and the 2001-2005 Toyota RAV4, along with other Toyota and Lexus models. Owners of other cars can look up their own year and model in the "Vehicles it fits" section. This listing is one bearing, and the 2003-2017 Toyota Sienna takes one.
