Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Backlash Inspection
- Install the drive shaft and intermediate shaft into the differential assembly.
- Secure the driveshaft (A) in a bench vise (B) with soft jaws (C). To prevent damage to the driveshaft, always use soft jaws or equivalent material between the driveshaft and the vise.
- Place the intermediate shaft (D) on a V-block (E), then fix the intermediate shaft using a grip (F) or equivalent.
- Measure the backlash of the final driven gear (G) with a dial indicator (H).
Standard: 1.1-1.6 mm (0.04-0.06 in.)
- If the backlash is out of standard, replace the differential carrier; 4WD (see DIFFERENTIAL CARRIER, FINAL DRIVEN GEAR, AND TRANSFER DRIVE GEAR REPLACEMENT ), 2WD (see DIFFERENTIAL CARRIER, FINAL DRIVEN GEAR, AND TRANSFER DRIVE GEAR REPLACEMENT ).
