My 2000 Expedition sometimes engages the front axles? when doing a mild accelleration up to around 50 mph. (The rear wheels are not slipping and the <a href="http://service.bfast.com/bfast/click?bfmid=37919709&siteid=39251846">tires </a>are all good.) The Ford crew at the dealership can't find the problem. It creates a very noticed jerking and slight hesitation. I had the transmission fluid changed and this seemed to help the problem for a few months. Just wondering if anyone had any suggestions. Thanks
I posted this a few days ago and noone has responded altough they have to many other posts--
I believe what you are experiencing is the driveline shudder that has been discussed on the forum before. In overdrive going up an incline you get a vibration-which feels like the truck has moved the power to the front of the vehicle. Check out the other posts regarding tranny vibration or shudder.
