The front drive axle clutch gear shim needs to be measured and adjusted if any of the following parts are replaced:
• | The inner axle shaft |
• | The inner axle shaft housing |
• | The clutch shaft |
• | The differential carrier case |
• | The ring and pinion gears |
• | The differential assembly |
• | The differential bearings |
• | The carrier connector |
Front drive axle clutch shims are available in the following sizes:
8.25 Inch Axle | 9.25 Inch Axle |
---|---|
1.27 mm (0.05 in) | 1.30 mm (0.05 in) |
1.52 mm (0.06 in) | 1.52 mm (0.06 in) |
1.78 mm (0.07 in) | 1.80 mm (0.07 in) |
2.03 mm (0.08 in) | 2.03 mm (0.08 in) |
2.29 mm (0.09 in) | 2.30 mm (0.09 in) |
2.54 mm (0.10 in) | 2.54 mm (0.10 in) |
2.70 mm (0.11 in) | 2.80 mm (0.11 in) |
3.05 mm (0.12 in) | 3.05 mm (0.12 in) |
3.30 mm (0.13 in) | 3.30 mm (0.13 in) |
3.56 mm (0.14 in) | 3.55 mm (0.14 in) |
3.81 mm (0.15 in) | 3.80 mm (0.15 in) |
-- | 4.05 mm (0.16 in) |
-- | 4.30 mm (0.17 in) |
-- | 4.55 mm (0.18 in) |
-- | 4.80 mm (0.19 in) |
2.1. | Install the inner axle shaft (1) into the inner axle shaft housing (4). |
2.2. | Install the thrust washer (with tabs) (5). |
Ensure the tabs on the thrust washer are aligned with the slots in the inner shaft housing.
2.3. | Install the thrust washer (without tabs) (6). |
2.4. | Install the retaining ring (7) into the inner axle shaft (1). |
Note: In order to obtain an accurate measurement, the inner axle shaft must be moved outwards before measuring.
This measurement is the distance between the inner axle shaft and the clutch shaft before subtracting the J 34673 .
This is the shim thickness for the front axle without having any axle shaft endplay.
Note the following examples:
• | If the figure obtained in step 8 was 3.53 mm (0.139 in), use a 3.30 mm (0.130 in) shim. |
• | If the figure obtained in step 8 was 3.30 mm (0.130 in), use a 3.05 mm (0.120 in) shim. |
Note: Use this method only if the proper tools for calculating the shim size are unavailable.
Use the chassis grease in order to hold the shim in place.
Do not use sealer at this time.
Caution: Refer to Fastener Caution in the Preface section.
4.1. | Install the J 8001 or the equivalent on the axle tube end. |
The plunger of the indicator must be at a right angle to the axle flange.
4.2. | Move the shaft back and forth and read the end play. |
The correct end play is 0.03-0.51 mm (0.001-0.020 in).
4.3. | If the end play is incorrect, install a thicker or thinner shim as needed in order to bring the end play into the specified range. |
