For the last few months, I've been chasing a 4wd gremlin that I thought was IWE related. Whenever I need 4wd, such as deep snow or sand, mud, whatever, and I'm on throttle heavy trying to get through, the truck will pop a few times, then completely lose 4wd. At first, it was just in certain high-bind situations.
The first thing the dealer, who is a very long time friend of mine, tried was replacing the vacuum harness. No better. Next we pulled the IWE's apart and inspected them, and it all looked fine. After that, we replaced a vacuum actuator that must be in control of the vacuum to the hubs. No change here either.
This sunday, a friend and I went to some local-ish sand dunes and were there for a few hours. I ran most the day in 2wd, then tried 4wd a little bit. As most of you know, sand is not the highest load situation to spin the tires in, so it should be fine, right? Wrong. By the end of the day the truck wouldnt stay in 4wd on even flat ground with minimal acceleration. This time when it started popping and clunking, I just stayed on throttle and let it grind and pop and do its thing, hoping to develop the problem to a point that we could find it.
Success! After the service writer, the owners son (close personal friend of mine) and a tech took my truck out in the snow today to make it act up, they drained the T-case and found it to be very metallic and low on oil.
Has anyone else blown up a transfer case yet? Its a '12 with 28,000 miles.
