Always something new. 3 button.
Hey, I just replaced my vac actuator and now theres a loud 'clunk' as it drops back to unlocked from 4 to 2. Sound is on pass side and the clunk is almost a bang.
Any ideas?
Thank's everybody.

 

Mines always had a clunk to it when the transfer case shifted. I thought it was normal?

 

I get no clunk coming out of, or going into 4wd. didnt in the blazer either.

 

Only get a clunk when going into 2L

 

i get the same thing. almost like you hit a pot hole some times. havent had any problems. i grabbed my bosses Ford 350 with and e-xcase and it does the same thing on his. bangs/clunks coming out of 4wd and back to 2 wheel. once his did it, i figured there is no point in worrying about mine. just make sure that there is fluid in it and you should be fine.

 

are you sure that your switch is even hooked up?!?!
yeah, i never get any noise going into 4wd but i always get a bang coming out.

 

Yup, 4wd works, have used it a few times this winter.
4wd worked on the blazer too. The only time I have ever heard a clunk, is if I was in 2wd, got stuck while going up a hill, and put it into 4 wheel while on the incline (that was in the blazer)
