3619-142 – Nose Bushing – Height 48.5mm – Inside Dia 14mm – 31mm OD – Partn Number 3619-142

When it comes to maintaining the driveline integrity of Cadillac vehicles, the 3619-142 nose bushing is a crucial component. This part supports the two-piece driveshaft at its midpoint, ensuring proper alignment and minimizing vibrations that can lead to premature wear. If you notice vibrations at highway speeds or hear unusual bearing noise, it’s likely time to replace your nose bushing with the 3619-142.

With an inside diameter of 14mm, a height of 48.5mm, and an outer diameter of 31mm, this nose bushing fits perfectly within the specified mounting geometry of Cadillac applications. The rubber isolator within the bushing absorbs vibrations, but if it becomes hardened or collapses, you’ll experience driveline vibrations that can affect vehicle performance.

To ensure a successful installation of the 3619-142, follow these practical tips:

• Do not pre-load the rubber isolator during installation.
• Align the mounting bracket before tightening to avoid misalignment.
• Check the driveshaft runout after installation to confirm proper alignment.

Replacing the nose bushing with the 3619-142 not only restores the driveline’s functionality but also enhances the overall driving experience by reducing unwanted vibrations. Don’t overlook this small yet vital component in your Cadillac’s driveline system.
