Differential — disassembly and assembly (Hyundai Elantra J2)

Disassembly

1. Loosen the drive gear mounting bolts and remove it from the differential housing.

2. Using a special tool (09433-21000), remove the bearing.



3. Using a punch inserted into hole "A", knock out the locking pin.



4. Remove the satellite shaft, satellites and washers.



5. Remove the axle gears and spacer bushings. Do not confuse the gears and spacers installed on the right and left sides.

Assembly

1. After installing spacers on the rear sides of the differential axle gears, install the gears into the differential housing. When reusing parts, install them in their original positions according to the marks made during disassembly.

When using new axle gears, install spacers of medium thickness 1.0 mm.

2. Install the washers on the back sides of the satellites. Install the satellites into the differential housing, then insert the satellite axle.

3. Measure the clearance between the axle gears and the satellites.



The gap should be 0.025-0.150 mm, and the gap in the pairs of gears on the right and left sides should be the same. If the clearance is outside the specified limits, disassemble the mechanism and reassemble it using other spacers that provide the normal clearance value.

Nominal value - 0.025-0.150 mm

4. Install the satellite axle locking pin in the direction shown in the figure. After installation, the pin should protrude no more than 3 mm.

Precaution. The locking pin cannot be reused.

5. Press the bearings onto both ends of the differential housing. When installing bearings, press on the inner rings. Do not apply pressure to the outer rings of bearings.

6. Install the differential drive gear onto the housing.

7. Apply automatic transmission fluid to the bolts and tighten them to the specified torque.

Tightening torque: 130-140 Nm
