Full Description
Center Support Shaft Section -- 3181-161
Multi-piece driveshafts depend on a precision midship stub shaft to maintain alignment between the carrier bearing and the propshaft tube. The 3181-161 provides a " bearing journal, a 16 X 1.375" spline section (7.375" long), and a N/A" butt diameter for N/A" tube welding -- everything needed for a correct two-piece shaft assembly.

Why the Bearing Journal Dimension is Critical
The center support bearing must press onto a journal that is within a few ten-thousandths of an inch of the bearing bore. The 3181-161's journal is ground to " -- use this measurement to look up the correct CSB part number. A mismatched bearing diameter is the most common cause of premature CSB failure and driveshaft vibration.
Tube Welding
The butt end accepts N/A OD tubing. Clean the tube bore and yoke butt before fitting. Tack at four positions, check runout, then complete the weld. Post-weld TIR at the bearing journal should be below 0.003" before the CSB is pressed on.
Style: Cvj
This is a slip-style stub shaft (telescoping splined section absorbs driveline length changes). Match the style to your driveshaft layout -- using a fixed stub where a slip stub is required will bind under suspension travel and can fracture the shaft.
