Quickly Identify Spicer Driveline Replacement Parts 

The Spicer ReadyShaft Dana EZ-ID Tool simplifies part identification without product numbers with an easy-to-follow 10-step process for collecting the dimensional data of the part. This information can then be utilized to identify the correct replacement driveline assembly parts needed. 

To begin using the platform, visit DanaAftermarket.com and click on the Spicer ReadyShaft logo on the home page. If you have the part number, great! Simply type it into the entry field (Fig. 1) to generate your ReadyShaft part number (Fig. 2).

But what if you don’t have a part number? No problem! Click on Click Here (Fig. 1). Once you have read the disclaimers and clicked Continue, move on to complete the following steps.

Step 1. Select the Spicer ReadyShaft Type 

Start by identifying where on the truck the shaft came from by selecting the appropriate button from the following options:

1.     Inter-Axle Shaft or Short Couple

2.     Driveshaft

3.     Coupling Shaft

Step 2. Select Short Couple or Inter-Axle Shaft 

Determine between a short couple or inter-axle shaft. Some helpful key identifying information is that short couple doesn’t include tubing; if tubing is present, this indicates an inter-axle shaft. Inter-axle shafts also contain two welds.

Step 3. Identify Yoke 

Determine the type and series of yoke you need with the Spicer® Ruler (Fig. 3) available on DanaAftermarket.com (part number RULER-SPICER-32020).

Figure 3. The Spicer® Ruler

Please note that if you are servicing a half-round yoke, you must replace bolts and straps every time.

Step 4. Select U-Joint Style 

Select the U-joint style from the following options:

  • 10 Series
    • Full Round (4 bearing plates)
    • Half Round (2 bearing plates; 2 bearing cups without plates)
  • SPL® Series
    • Greaseable (4 bearing cups with dual grease zerk in center)
    • Service-free (4 bearing cups without grease zerk)

Step 5. Determine Tubing Length 

To determine the tubing length, measure from center of weld to center of weld (Fig. 4).

Figure 4. Weld-to-weld tube-length measurement

Step 6. Measure Collapsed Length 

Compress both ends to collapse the shaft; physical feedback and an audible click will signal that the shaft is collapsed. Once accomplished, measure:

  • From center of U-joint to center of U-joint
  • Flange face to flange face
  • Center of yoke to center of flange face

Step 7. Measure Installed Length 

To determine the length of a damaged or missing driveshaft, you can obtain the following dimensions (Fig. 5) to identify the correct part:

  • From center of U-joint to center of U-joint
  • Flange face to flange face
  • Center of yoke to center of flange face
Figure 5. Installed length measurement

Step 8. Calculate Tube Diameter 

Measure your tubing diameter (Fig. 6) in either inches or millimeters.

Figure 6. Tube diameter measurement

Please note that if your measurement or selection is not displayed, your driveshaft may not be offered through this program. Please contact your local original-equipment manufacturer to verify your part number.

Step 9. Select Phasing 

Phasing refers to how the ears of the yoke are oriented to each other (Fig. 7). Phasing is calculated and implemented at the OE level to counteract vibrations in the driveline.

Figure 7. Phasing calculation

Please note that we do not recommend taking a driveshaft apart and rewelding it so that it’s in phase or out of phase from the original factory specifications.

Step 10. Determine Yoke Angle 

Calculate high/low yoke angle by measuring from point of weld to center of U-joint at tube/weld yoke (Fig. 8).

Figure 8. U-joint angle measurement

Once you select the correct yoke angle, your part ReadyShaft part number will be generated so you can place your order.
