Click here for Part 1 of this article: About your transfer case problems
A list of some more of the basic problems, and some solutions
Your transfer case is noisy, or "jumps" out of the 4×4 low range:
- Your transfer case may not be fully engaged. Stop your vehicle, shift into Neutral, and then engage 4L (4×4 low gear).
- Your shift linkage may be loose, worn or binding. Tighten, repair or lubricate the linkage as necessary.
- The shift fork may be cracked, the inserts worn, or the fork binding on the rail. Disassemble the unit and repair all problematic parts.
- It's also a good idea to Inspect the bushings on the linkage; they may need to be replaced.
There are lubricant leaks from the vent, or the output shaft seals:
- The transfer case may be overfilled. If so, you need to drain it until the fluid is at the proper level.
- The vent may be clogged or jammed closed. Clear or replace the vent. If your vehicle has extended vent tubes, make sure tubes aren't sagging — this could be allowing fluid to collect, and not drain properly back into the case.
- It's possible that the output shaft seal is incorrectly installed or damaged. In that case, you need to replace the seal, and check contact surfaces for nicks and scoring.
