3 SPECIFICATION

06-4 3310-00 1. OVERVIEW The propeller shaft transfers the power through the transmission and transfer case to the front/rear axle differential carrier (final reduction gear).

4 OVERVIEW The propeller shaft transfers the power through the transmission and transfer case to the front/rear axle differential carrier (final reduction gear). It is manufactured by a thin rounded steel pipe to have the strong resisting force against the torsion and bending. Both ends of propeller shaft are connected to the spider and the center of propeller shaft is connected to the spline to accommodate the changes of the height and length. The rubber bushing that covers the intermediate bearing keeps the balance of rear propeller shaft and absorbs its vibration.

3310-01 06-7 Manual Transmission Automatic

7 Manual Transmission Automatic Transmission (For Gasoline Engine) 1. Remove the flange yoke mounting bolt on the transfer case side of the front propeller shaft. - Put installation marks on the yoke to the propeller and the flange to the transfer case.

8 Remove the flange yoke mounting bolt and nut on the front axle side of the front propeller shaft. - Put installation marks on the yoke to the propeller and the flange to the transfer case. 3. Remove the front propeller shaft.

9 Remove the yoke mounting bolt and nut on the transfer case side of the rear propeller shaft. - Put installation marks on the yoke of the rear propeller shaft and the flange of the transfer case.

10 Remove the intermediate bearing(center) bolts. 3. Remove the yoke and flage mounting bolts and nuts on the rear axle side of the rear propeller shaft. Then, remove the rear propeller shaft.

11 ) Disassembly 1. Place an alignment mark and remove the propeller shaft. 2. Place an alignment on the spiders before removing. 3. Remove the snap ring with snap ring pliers. 4. Tap the yoke shoulder on shaft with copper hammer to remove the roller bearing. Remove the other bearings with same manner. 5. If it cannot be removed, hold the welding area with vise and remove the needle bearing by using a suitable drift and hammer.

12 Disassemble the universal joint. The universal joint compensates the angle changes due to vertical movement of the axle shaft. 7. Remove the intermediate bearing bracket and remove the bearing with special tool.

13 ) Check 1. Visual Check Check the components for wear and crack and replace if needed. 2. Outer diameter of spider journal. Specified value Limit mm mm 3. Clearance between spider journal and bearing. Specified value Limit 0.03 ~ mm 0.25 mm 4. Run-out of propeller shaft Set up the dial gauge on the center point of propeller shaft and measure the run-out. If the runout is out of the specified range, correct it with press or replace it with new one. Limit 0.4 mm 5. Starting torque of universal joint. Specified value 3 ~ 8 kg.cm 6. Major causes of vibration - Balance weights missing - Excessive run-out of propeller shaf - When using the general bolts - Excessive wear of universal joint - Stuck in sleeve joint - Vibration is mainly caused by the angle changes in front and rear universal joint. It normally occurs when the vehicle speed is 60 ~ 100 km/h.

14 ) Assembly Clean the components and replace if damaged. 1. Align the alignment marks on the yoke and assemble the spider, bearing and snap ring. 2. Apply the grease to the inner lip of needle roller bearing and assemble the needle roller. 3. Install the yoke bearing shaft on the shaft and insert the spider. Place the cap on the opposite side and tap it with plastic hammer to seat it. Adjust the clearance of spider below 0.1 mm and install the snap ring. 4. Install the intermediate bearing to the rear propeller shaft. 5. Apply the grease on the propeller shaft and install it.
