Anyone? How to pictures/video remove transfer case 241 DHD 97 Dodge

Have to remove my TC 241 DHD per advice from a Dodge Guru. Trying to engage 4x4 on it's own while traveling at highway speeds. Sounds like a boat trailer winch ratchet but faster, as I slow down to about 20 mph it goes ker-plunk and my feet can feel the ker-plunk on floor. Are my shifting fork nylon bushings worn out and letting the fork creeping over to engage. My 4x4 dash light shows its in 4 wheel drive but will go out as I continue to drive. Anyone know of a good video on how to remove TC from truck and how to install the nylon spacers ( whatever they are called )? It is a 5 speed manual

Thank you...I love this forum!!

It could be a vacuum issue. The front axle is three pieces. Driver side shaft, the the passenger side is a 2 pieces. When 4 wheel drive is engaged, the vacuum lines come into play and a fork connect the two shafts. That could be the issue. Itís called a CAD. Center Axle Disconnect.

I agree, before tackling the transfer case, I'd spend some time researching the CAD. Easy to get at, and there are several moving pieces that could be suspect. I had an occasional clunk and when I pulled axles to put new seals in, I found a plastic bushing (actually pieces) that was part of the axle and CAD assembly.

good luck

thank you for your help! How would I check that? It tries to engage all on it's own?

Iím not crazy familiar, but it would be a vacuum issue. When you KNOW itís in 2 wheel drive, crawl under the truck and unplug the black and red lines connected to the axle half way between the diff. and steering knuckle. Truck need to be running due to the vacuum being gear driven.

I am pretty sure the light works off the CAD when the fork moves it clicks the switch. So that tells me the problem is at the transfer case because the valve that sends the vac down to the CAD is there. It seems to me the linkage might be moving it into gear. I would try to see what the linkage is doing when you shift it in and out of 4x4. Try to make sure it is all the way disengaged. The split axle on the pass side should have both shafts moving the same speed and should not grind much if any.

Unless the TC has been apart and somebody messed up something going back together, it should not be grinding at all. You shift fork plastics tabs being missing would make it not engage enough, not too much. Also there should be no grinding becasue it has a big syncro int it. It also has spring loaded locks to hold it in 2x4 or 4x4. If somebody put it back together wrong, ll bets are off.

Grinding is usually in the CAD as covered above.

Check all vacuum tubes for connection an d leaks.

Check the two under the trans fer case and see if them may have been pulled off or crossed when working on TC. Crossing them will make the CAD go in and out of gear opposite where it should be.

Check the vacuum solenoid in the CAD for moving fully in each direction.

If you do find nothing wrong with vacuum lines and CAD, get back and I can give you simple instructions for TC removal.

You can use a vacuum gauge(15 dollars or fee rent) or simply watch/listen/feel it when somebody up top operates it while sitting. It is like looking for juice with a voltmeter. except for small leaks it is like power, either there or not at the proper level. I do not know the number. You can even pull them and feel for vacuum with your finger. CAD's are known for not going into gear(sliding splines) adn grinding or not going in or out correctly. It can be due to vacuum leaks, a bad vacuum solenoid ,or a bad shift fork in it.

You might try switching those two lines on the cross member first and se what it does.
If they are crossed you will shift it but it will think you have shifted it but it will not engage the front axle.

Do you have any heater or cruise control issues?

Please post you truck info in signature, model, options, miles, mods etc and add location.

Ps there are vacuum connections near the TC above the connection on the crossmember and the switch is on top of the TC and removable without TC removal.
