Please look at the terrible transfer case fluid after 20K miles. Somebody in the forum mentioned that we should change the transfer case fluid every 20K miles to avoid the transfer case issue. Wow, I did it today and I was shocked to see how terrible the fluid was after 20K miles. Please use the new plugs with the new plugs. I was cheap and try to reuse the old fill plug. I see some sweat around the fill plug, I switch to the new one and I don't see it anymore.



Test drive and run smooth. New oil change, Transfer case fluid and Carbin filter. I was planning to do diff fluid, but I decide I will do it next 10K, 60K miles. Carbin filter is dirty I would recommend to replace it every year after the fall season.
Will reset the service interval with Durametric tomorrow. Front Brake is next few weeks. Will change the air filter tomorrow morning with Stock. Currently have BMC, I see no difference in performance. I would not do BMC air filter again. I did Spark Plugs at 30K, way early. I should do the plugs at 40K.

 

I agree, every 10k for TC fluid is worth it. I reused the original plugs with just a little silicone RTV in the threads and it doesn't leak at all. Those plugs are expensive for no reason so I wouldn't buy new ones every time.
