I will admit I had the work done at a shop. No time to crawl around under the truck. Plus, since this is not something that has to be done real regular, like an oil change, I am willing to pay for the service to be done. But I will admit I was amazed at how the binding went away after the fluid change. Truck also is quieter on the highway!! My truck only has 50k on it, so this was the first change for all the fluids.

no additive here is that post http://www.explorerforum.com/forums/...d.php?t=258015 great links in there if you haven't found it

the TSB that I read recently stated that this was caused by false 4wd engagement. the truck thinks the wheels are slipping,which they probably are while trying to park and thus the truck tries to engage 4wd before it realizes it shouldnt.
