- 2007 Mountaineer Base
Hello everyone, this is my first post on this forum after lurking for sometime.
I recently found what I thought (and hope still was) a good deal on a 2007 Mountaineer 4.0 Base with the tow package. Unfortunately, it has an issue that has proven to be a little troublesome in diagnosing.
When accelerating under load, there is what I would describe as a banging or popping noise coming from the drivetrain. The sound is entirely dependent on the load placed on the vehicle and is not present at cruise. I originally misdiagnosed this as bad CV axles and replaced the front pair with Motorcraft replacements. This did not solve the problem so I enlisted the help of my more mechanically inclined brother and we isolated the sound to the general area of the transfer case. From reading these forums I gathered that the issue could either be a bad CV joint on the front drive shaft or it was a problem inside the transfer case. It seems that the general consensus is to pull the front drive shaft; if the noise goes away you know the drive shaft is bad, if it doesn't go away you know it is a transfer case problem.
When we pulled the front drive shaft, we discovered that the vehicle would not move at all. There was a rather awful sound that--to me--sounded like some sort of electronic motor trying to engage or disengage. We installed the front drive shaft again and the vehicle again operated as it was prior to the shaft being removed.
Given that the vehicles drives beautifully otherwise and appears to have been very well maintained, I am fairly confident that it is not a transmission issue. Since the vehicle appears to not be sending any power to the rear wheels, that would indicate to me a transfer case issue. Subsequently, I ordered a transfer case from a junkyard online, and it is supposed to arrive in the next couple days.
Here is my big concern though, I'm not sure if I ordered the right one.
The part I ordered is for "6L24-7A195-AF thru AH" according to the website. RockAuto lists two part numbers (RTC4414F1 and RTC4412F2) for 4.0L AWD vehicles. According to CarID, it looks like those parts are interchangeable. I couldn't imagine that Ford would use different transfer cases on the same year and drivetrain of a vehicle, but it appears that might be the case and now I'm concerned that I will have the wrong part when it arrives.
Hopefully some of you who are more familiar with these vehicles can help me figure out what is going on here.
Thank you in advance!
