Clunking sound when shifting out of 4wd

I'm at work right now and just got back from going to get something to eat. While I was out I had to use 4wd to get out of the parking lot without sliding into other peoples cars. I turn the knob back to 2wd once out of the parking lot and I hear this clunk-I'm guessing coming from the transfer case? I was like WTF? Is this normal, this is the first day I've had to use the 4wd so I'm not sure.

 

can you make a video sound clip?

 

My truck does that the odd time as well. Not to worried about it.

 

in my first gen, it did the same thing to me once...pressed button and it took a few extra seconds to shift out, now i make sure to be going straight and slow and no gas. and if it takes a little longer, i just push the button quickly to stop it, then try again.

 

Yeah, mine does it sometimes too. I believe it's alright.

It does it less when you switch while driving straight ahead. While turning, both axles are trying to turn at different rates, but are locked together by the xfer case, thus, the klunk of the driveline bind releasing when you go from 4 to 2wd.

 

I always let off the gas when shifting in or out of 4wd but this was something I've never heard before in any of my previous trucks. This was on a straight stretch of road. Thanks for the input guys.

 

x2. Every 4x4 I've had (Jeep, Dodges, Tacos) has done the same.

 

Speaking of 4wd... is it ok to leave it parked in 4hi overnight?

 

Yup. I do that, when im parking/parked in a really crappy area that will most likely prove slippery or difficult to pull out of when im ready to leave. I wouldnt leave it in 4low, though, i image, that wouldnt hurt it either, i woudl just hate to forget its on and go above 25 mpg. but leaving it in 4high is fine.

 

Do you by chance have a diff drop installed?

 

I would love to be getting 25 MPG!

 

100% stock

 

you will be reminded very quickly it is in 4lo when you take off... you will not pass go, you will not get 25 mpg. You will not go past 30mph

 

^tx2, or don't give it enough time after backing off before turning the knob. I take it as a warning to be more careful next time.

 

Agree with the above, but also, have you had the front propeller shaft checked to make sure it is not in the recall range? Mine was clunking quite loudly when I switched out of 4wd, even when I was moving less than 5 mph. I got the recall done and it is much better now.

 

LOL...and if you put as much foot in it as you do in 4hi you'll be looking for a chiropractor to repair spinal damage.
