I'm having some issues with my Series III Landy's transfer case and I was wondering if anyone else has had similar problems. The symptoms are a grinding or clunking noise coming from the transfer case when I engage four-wheel drive, but it seems to be working properly otherwise. I've checked the fluid level in the transfer case and it's at the recommended level, so that doesn't seem to be the problem. I've also inspected the transfer case for any signs of wear or damage, but everything looks okay. Has anyone else experienced this issue? Are there any common causes or solutions that I should look into first? Any advice would be greatly appreciated!
