Unhappy 4 Wheel drive noise

I have a 1995 2500 Ram 4x4 that has a clunking and vibrating sound when in 4 wheel. All the noise is in the front and also feels like the front diff is "locked" - the front tires sort of jump when I turn. All u-joints in the front driveshaft and at hubs are brand new. This noise is only happening when in 4 wheel and under load (foot on gas) - smooth as silk in 2 wheel. Dana 60 front axle. Whats up here?!? Any help is much appreciated. Not to happy w/ Dodge right now - my '02 is having the tranny replaced after much arguing w/ dealership........

Hey when I first got my 94 1/2ton I couldn't bust out of a wet paper sack let alone get my truck up a gravel embankment. Had my buddy pull me up the friggin hill or I was f----- and he drives a bronco. Found out I had a burnt vacuum line going to the front diff.
Although when I cranked my wheels I would get the hop and skip like I WAS in 4WD.

Thanks, will check that tonite along with checking if 1 of the u-joints behind the hubs is froze - I would think that would make it cause the same problems I have....Also going to try to check some of the electric actuators for bad wires.....

The jumping or hoping skipping is always there. Just the front wheels covering more ground than the back wheels and they are locked together when in 4 wheel drive and in a tight turn. As for the clunking vibrating sound...both of mine do make a little more noise in 4 wheel, I guess more vibration. Is the clunking continous? Intermittant?

its almost more of a slipping - like the splines aren't engaging all the way. This weekend I'm checking the splines behind the wheel bearings and under the vacuum actuator. After that I'm lost........

This will sound stupid but I don't mean to offend... Are you doing this on pavement or a hard surface? 4wd is for loose surfaces. If the front wheels are getting too much traction (same as the rears) you will get this reaction. Otherwise you are going in the right direction by checking axle u-joints and the center axle disconnect. There is a kit out to eliminate the thermal/Vaccum disconnect. A vac leak will cause the collar to partially/ completely fail to engage. Good luck and keep us informed... Chris

was testing it on a grassy surface. Anyway, curious about the kit to eliminate the vacuum dissconnect - wouldn't that just give u full time 4WD?. Replaced the gaskets and plastic bushings in the vacuum actuator, but it wasn't that. Took front drive-shaft out to see if maybe one of the u-joints replaced was also bad and noticed the spring loaded bearing in the velosity joint didn't look too hot so I replaced it and problem solved. Can't feel or hear anything in 4 wheel.
