Transfer Case: Testing and Inspection

Transfer Symptom Diagnosis





Before attempting to repair the transfer or related components for any reason other than mechanical failure, the condition and probable causes should be identified.
Transfer failures are revealed by shifting difficulties such as excessive shifting effort, gear clash, or gear grinding. When any of these conditions occur, the following inspections should be made before disassembling the transfer.
1. Check transfer oil level for insufficient or incorrect oil.
2. Check transfer mountings for wear or looseness.
3. Check gearshift control lever for distortion or excessive wear.
After performing the above inspections, refer to the diagnosis table.
