📏 Technical Specs:
| Spec | Value |
|---|---|

| Inner Diameter (ID) | Approx. 1.68 inches |
| Width/Height | ~0.5 inches (varies slightly) |
| Construction | Metal-clad rubber seal |
| Features | Spring-loaded lip, dust boot (on some variants) |
| Seal Type | Rear output/yoke seal for 4WD housing |
🔁 Cross-Reference & Alternate Part Numbers:
| Brand | Part Number |

⚠️ Important Distinction:
There are two types of A904/A500 extension housing seals:
| Part Number | OD | Application |
|---|---|---|
| 12074J | 2.568" | 4WD (4x4 only) |
| 12074 or 12074M | ~2.506" | 2WD or compact applications |
Do NOT interchange these — the difference in OD makes them incompatible.
🛠️ Usage Notes:
-
If you're working on a 4x4 vehicle , especially with a transfer case attached directly to the transmission, this is the correct seal .
-
Install using a seal installer or large socket , tap in evenly.
-
Grease the inner lip before sliding in the output shaft to prevent dry wear.
