The features are: The structural method of press fitting unit bearing into front hub is applied. The wheel bearing uses a taper roller unit bear- ing. A rotor for detecting the wheel speed is press-fitted to the UJ outer wheel. NOTE: DOJ: Double Offset Joint. UJ: Under cut Joint. Drive shafts incorporate UJ-DOJ-type constant velocity ball joint has high power transmission efficiency and reduces vibration and noise. A vacuum-type free wheeling clutch has been adopted in the freewheel mechanism. Its solenoid valve and actuator Switch powertrain between RWD and 4WD. The differential support method is a four-point elastic support method which reduce vibration and noise. FRONT AXLE DIAGNOSIS INTRODUCTION TO FRONT AXLE DIAGNOSIS M1261005500210 The 4WD vehicle incorporates a free wheeling clutch as the free-wheeling mechanism. The free wheeling clutch is configured of the mainshaft, shift fork and clutch gears, etc., and is electrically controlled. If the clutch does not lock or locks but does not become free, there may be electrical trouble or the component may be faulty. Noise from the driveshaft, inner shaft or differential can be caused by a compo- nent defect. FRONT AXLE DIAGNOSTIC TROUBLESHOOTING STRATEGY M1261005600110 Use these steps to plan your diagnostic strategy. If you follow them carefully, you will be sure that you have exhausted most of the possible ways to find a front axle fault. 1. Gather information from the customer. 2. Verify that the condition described by the customer exists. 3. Find the malfunction by following the Symptom Chart. 4. Verify malfunction is eliminated.
