3R80-35 – Center Support Bearing – Buick Application – 1.574″ ID – Notes Buick, Bearing not included

Buick is an uncommon application in the center support bearing catalog -- most of the 4180-series and related units serve Ford, Dodge, and GM truck platforms rather than Buick passenger and crossover lines. The 3R80-35 covers Buick two-piece driveshaft applications with a 1.574-inch inner bore, shared with the 1350/1410-series bore family. However, the bracket geometry and center-to-base height are specific to the Buick platform and should be confirmed against OE dimensions before ordering.

Center Support Bearing

Center support bearing failures on passenger car and crossover applications often go undiagnosed longer than on trucks because the vibration presents differently. On a lighter-duty Buick platform, a failed rubber isolator produces a subtle resonance -- sometimes interpreted as road noise or tire out-of-round -- rather than the more obvious clunk or roughness that heavier drivetrain loads produce on trucks. If you have eliminated tire, wheel, and suspension as vibration sources and are investigating the driveline, inspecting the center support bearing is a logical next step.

Key measurements to confirm before ordering: inner bore (to match stub shaft OD), center-to-base height (to preserve driveshaft angle), and bracket bolt pattern spacing. View the complete center support bearing catalog for all available units.
