croquet

I have a 2005 5.4 engine F150. The truck has an electric shifter and usually shifts into 4wd immediately. Lately, there has been a hesitation both going into 4 wd and coming out of 4 wd. Anybody have any ideas?

Explain Hesitation ?? at what speed ?

Thanks for replying. It was a cold icy morning. I started the truck and moved it into 4wd. It hesitated for less than a minute and then eventually engaged. After I was out of the driveway, the switch back was delayed less than a minute, but eventually clicked in.

you may have some moisture in the vacuum lines that freeze... Basically an ice cube blocking the vent or vacuum line's
