Subject: 93 transfer case problem
IP: Logged

Message:
My 93 Dakota 4x4 has a strange problem. If I use the 4 Whl drive, when I push the lever back to 2 whl drive, the transfer case stays engaged. You can hear the whine. Sometimes if I stop and place it in park and shut off the engine, then restart, it is okay. Lately however it stay engaged for a long time. The lever and shift are free and move as they should. Has anyone had this problem before and how did they fix it?

Alex,
Do you think the front drive shaft was the cause or result of the problem? I also found I put some GL5 80W gear lube in on top of the ATF that is supposed to be in there. I am going to drain and refill.

it sounds like your vacumn actuator on the front axle is sticking.
do a search on this site under the Dealer,TSB's and Recalls page
on 4 WD and you will find some good info

Tailg8tr--Thanks for your advice. However, I cannot find a vacuum actuator on the front axle. The All data book shows only an electrical switch on the transfer case for the indicator light. The diagram further talks about it as a vacuum switch but from all examinations it looks like it is a strictly mechanical system. Am I missing something?

On your '93, I believe it is like my '89, using a central axle
disconnect, or CAD. It runs on vacumn from the T-case. Look
at the passenger side axle where it comes off the diff. There
should be a housing and a vacumn switch. The vacumn switch
looks like two pie tins pressed together. This actually shifts a
fork in the CAD housing....look at an exploded view in a Haynes
manual at Advance auto or Autozone. The electric sensor only
trips the 4WD light on the transfer case shifter bezel. Try a
search on this site in the Dealer recalls section, you are looking
for a reply by walt_felix to a post titled 4 WD This is where I'm
getting the info. Check it out.

It is more than likely the vacum switch located on your transfer case. If it were the diaphram on the front end it wouldn't have engaged in the first place. Switch on transfer case located on driver's side near extionsion housing of t case (should have 4 line's attached). Unplug line's from switch take switch off, iflever in 2 wheel position the spring loaded ball should be out about half an inch or more. If it if less squirt some penatraiting oil in end where lines go and work till it pop's out. If still persits go buy two of those switches (one to use one to put in glove box) I've fought the one on mine from day one and it is soon to get a positive system. Summit carries a kit to eliminate vacum. Or an off road store may have it for a Jeep Wrangler (think summit's is that way also) but same front end just ifs.

93 there is no vaccumm bull to mess with, the front axle is permanently locked in and the transfer case just has the shift lever. as for the staying engaged mine has done it a couple times, just try going into reverse for about 10 feet, sometimes that works, i dont know the cause of the problem.

Ted, my 92 had this problem. took me a while to figure it out but finally tore down the t-case and found the plastic guides on the shift forks had fallen off or worn through and the shift forks were worn so thin they couldn't fully disengage the 4 wheel drive. after that repair i had troubles again this years with 4wd staying engaged and it was the vac switch on the t-case that erick mentioned.

Hi, I just swapped out my t case on my 93 dakota with a t case from a 96 Ram they were both np 231 with 2.72 ratios, the only difference was the output shaft was much larger on the new transfercase, I had a new yoke made and everything seems to be going together great. Now for my questions, First off what kind of fluid should I use in the t-case? and secound does anybody see any problems with this type of swap that I may have overlooked?

I agree with JT, probably the shift fork pads or the forks themselves. Had to replace the fork in mine. As for the fools talking about vaccum and axle disconnects, that system is only used on full sized trucks. NOT Dakotas and Durangos. If you rebuild your transfercase try and find an 93 or older 241 transfercase from a Dodge, Jeep or Chevy and steal the 6 gear planet out of it. This will almost make it as strong and the 241. The newer ones have a different gear angle. Also, any 97 or older transfercase should bolt right up out of full size Dodge trucks or Jeep or Dakota. The 98 and newer Dodge do not have the speedo hole and can not be used.

Sorry guys, let me correct myself. None of the independent front suspensions with the CV half shafts use vacuum actuators. Also, there are a couple different input shaft lengths but should not be a problem from Dodge to Dodge but may need to be changed out from Jeep to Dodge. Also, if you use a t-case with a different front output yolk than yours has just use yours and change the seal while you are at it. I believe it is a 1 1/8 socket.
