For over 2 yrs I have lost the capability to disengage the axles on '07 H3x so it may be towed behind motor coach in Park

Have reviewed owners manual towed this hummer 4 10 yrs stopped in 2008

Need to identify the prob and how to restore the capability to tow behind motor coach

Was the engine running?

A pretty loud clunk is normal. There's nothing to lubricate except to make sure you're changing the transfer case fluid on a regular basis. I would change it often, like every 20,000 miles. Takes less than 2 qts of Dexron VI, cheap maintenance that goes a long way towards prolonging the life of the transfer case.

If the engine is running and the transmission isn’t in park, you will get a clunk bang.
