Question(My 2007 x3): My transfer case was changed to a used one and it removed the ABS/Brake/4x4 lights from being on. Now I hear a scratching sound from the back that was NEVER present before. Do you have a professional opinion what could be happening or what could be checked?

Hi guys random atc400 functionality question. Without the actuator on the t case the spreaders are closed, does this fully engage front drive shaft or fully Disengage it? And is it safe to say that fully spread is the opposite?

Hello Sean - I am trying to troubleshoot my ATC400, and wondering should the assembly at timepoint 3:59 allow the input shaft from the servomotor to rotate a full 360, or should there be some resistance from the clutchpack limiting the rotation? I've replace my servomotor and ECU, get the TC still will not calibrate. Debating if I'm going to drop the TC or just send the car down the road. Great video!
@miketurin5233 4 жыл бұрын
There should be tough resistance when you turn the shaft where the Serv motor connects. It should turn back really fast and hard once you turn it with your hand.

Mine was jerking/stuttering when going up a hill under pressure. Also I had a noise like plonk/plonk coming when rolling slowly and shift in N and then push/pump the throttle and release. Felt like a rubber band release. Also disconnect your transfer case by disconnecting the electric gear motor in the transfer case. It’s just a plug and can be done quickly under the car. No need to jack up. You car will drive in rear wheel mode only. If any symptoms are gone then it’s the transfer case.

Good video. I may need one too. Can you or someone HELP answer a question for me. My 07 x3 3.0si is rattling at the center bottom of the vehicle at rpm's at about (12-1500) in park, drive, neutral also while moving. IDK if the Transfer case has any power or movement to it while in park. I had the car up flushing my brake fluid and friend gave it gas in P, N, and Drive and it was way louder than I thought. Sounds like bad bearings or marbles inside somewhere right on or near the T.C.. The Exhaust is right next to it and was just wondering if it's that nylon worm gear, Transfer case or possibly Cat Convertor or even Torque Converter? going bad. Any help would be greatly appreciated. Thanks-Peace-

Good video! I'm trying to do the same for my 2005 X3 as well. Ran into a couple of problems though. One is that one of the bolts broke and I'm having a tough time trying to get it out. Tried a few things but it won't get out. Then i thought i would just open it up and hopefully i can just twist it and get it out that way. But now I'm having trouble separating the two halves. The video says a puller is used. May i ask what kind of puller would work? I have a few pullers but they seem to be way too short/small to be secured against the case.

Hello. Dealer just called with a $4500+ replacement cost of the ATC400 transfer case. This video is a lifesaver. The car was studdering or jumping during acceleration and very occiasionally flashing a 4x4 light. I have already replaced the plastic gear in the xcase motor actuator. After watching this video I am imagining that the chain is jumping teeth. Is that a fair assumption? Other than the chain and bearing kit, what about the seal kit? Would that be a plus to replace? Also, are these case bolts aluminum and require replacement after every torque up? And finally, is the sealant for the case half the same that they use on the differential cover (loctite 5970) now? Great video and thanks for the info.
@seanbking 6 жыл бұрын
Darby Mirocha it's probably a lose chain. The seals I didn't replace because they weren't leaking. If yours aren't I'd leave them be. The gray sealant is permatex ultra grey. Reuse the same bolts.

Thanks so much. One more thing. I am using loctite 5970 for the case half. What is the cure time before filling with fluid? The MSDS says 7 days before subjecting to 'heavy loads'. I don't think an non-pressurized transfer case is a heavy load, but I don't want to be impatient either. How long did you wait before filling with fluid?

the actuator is a notorious, common fault with e83s but the transfer case going bad isnt at all common... and the only reason the actuator goes is because some idiot engineer designed the worm gear to be made out of plastic (the motor itself doesnt go bad). plastic gear next to catalytic converter = bad news.

with the face lifted models, the transfer case was redesigned, and no longer uses a chain. Rather it uses gears which spline together. When these units fail, more than likely, not going to be worth rebuilding. Unfortunately, you have to replace the whole unit.

clunking was definitely one big indicator for mine too. if/when you drain the fluid you should be able to see the chain through the filler hole. if you're able to move the chain easily with a screwdriver etc..then the chain needs replacing. also if the Christmas lights of death come up on the dash and it only lets you drive in 2Wd, the n it could be the transfer case actuator gear..which is only a 25 fix. there are plenty of videos about that on you tube.
