WARNING: This page is about a different car, the 2019 Nissan NV3500 HD, 2019 Nissan NV2500 HD, and 2019 Nissan NV1500. However, it is still accessible from the selected car via links, so may be relevant.
- Clean the threads and splines of the drive pinion.
- Drive the new front oil seal in evenly until it becomes flush with the gear carrier using Tool (A).
Tool number (A)
:--(J-50982)
CAUTION:- Do not reuse front oil seal.
- Do not incline the new front oil seal when installing.
- Apply spline sealant 1.5 mm (0.059 in) diameter bead 360 degrees around splines inside of the companion flange and install it on the drive pinion, aligning the matching marks.
- Use Spline Sealant (Loctite 565) or equivalent. Refer to Recommended Chemical Products and Sealants .
- Install the new drive pinion lock nut and washer and temporarily tighten using Tool (A).
Tool number (A)
:--(J-45012)
CAUTION:- Do not use power tool to install drive pinion lock nut.
- Do not reuse drive pinion lock nut or washer.
- Measure and adjust the total preload torque as necessary using suitable tool (A).
- Use the pre-measured total preload torque recorded during removal and add an additional preload torque "A" to the recorded pre-measured value. Use this calculated value when adjusting the total preload torque "T", when not replacing the collapsible spacer.
Pre-measured total preload torque + Additional preload torque "A" = Total preload torque "T"
Additional preload torque "A"
: Refer to Preload Torque .
Total preload torque "T"
: Refer to Preload Torque .
- Tighten drive pinion lock nut in increments and measure total preload torque several times to prevent overtightening.CAUTION: Do not loosen drive pinion lock nut to adjust the preload torque. If the total preload torque exceeds the specification, disassemble and replace the collapsible spacer and the drive pinion front bearing. Then tighten it again to adjust. Refer to Disassembly and Assembly .
- Rotate the drive pinion several times, each time the drive pinion lock nut is tightened to seat the pinion bearings.CAUTION: After adjustment, rotate drive pinion back and forth two to three times to check for unusual noise, rotation malfunction, and other malfunctions.
- Use the pre-measured total preload torque recorded during removal and add an additional preload torque "A" to the recorded pre-measured value. Use this calculated value when adjusting the total preload torque "T", when not replacing the collapsible spacer.
- Installation of the remaining components is in the reverse order of removal.CAUTION: Fill the rear final drive with new differential gear oil level after installation. Refer to Changing Differential Gear Oil .
