3-1-32R – Companion Flanges – 1.401″ Splines Dia – 32 Splines – 1.943″ Hub Dia

3-1-32R is a critical component for anyone working on the rear transfer case of a 2007-2017 Jeep JK. When you encounter issues like vibrations or improper alignment during driveshaft installation, the problem often lies in the companion flange. This specific flange connects the driveshaft to the transfer case, ensuring smooth power transfer. If the flange face isn’t perpendicular to the rotational axis, you’ll experience runout, leading to unwanted vibrations at various speeds.

The 3-1-32R features a robust design with 32 splines and a spline diameter of 1.401 inches, providing a secure fit with compatible driveshafts. The hub diameter measures 1.943 inches, while the pilot diameter is 2.000 inches, ensuring a snug fit against the transfer case. Additionally, the bolt circle diameter of 4.250 inches allows for easy installation. When replacing or upgrading, make sure to clean all mating surfaces and torque the bolts in a star pattern to avoid future issues.

• 32 splines for enhanced compatibility
• 1.401″ spline diameter for a secure fit
• 1.943″ hub diameter ensures proper alignment
• 2.000″ pilot diameter for efficient assembly
• Check face runout to prevent vibrations

Remember, proper installation is key. Always verify that the flange face is perpendicular to the axis to avoid any alignment issues down the road.
