Grinding/Clunk Intermittent Noise
I'm having a problem with my 4WD (I'm guessing, brakes and everything else works fine), about 4 times now I'll be driving down the road and will hear a loud grinding noise and clunk that sounds like the 4WD isn't all the way engaged (running in 2wd), which goes away after I stop. I took it to the dealer and they found a small vacuum leak on the 4WD system, but it happened again tonight after getting it back yesterday. Any ideas on what this might be, or others that have had a similar problem? It's going back to the dealer, just curious if others have had the same experience, mines an 04 SCREW 4WD with just under 15K miles. Thanks....
