When your transfer case goes bad, your car might jump in and out of 4-wheel drive on its own. This indicates an inability to stay in a drive mode which can damage the transfer case, other systems on the vehicle, or cause an unsafe driving situation.
Two-wheel transmissions have no transfer case. However, some vehicles like the two-wheel drive Ford Bronco II, have a dummy transfer case to ease conversion to four-wheel drive by only requiring a new output shaft.
There is no set time or mileage. We’ve heard of transfer case where they only last 6,000 miles (rare) and others that have lasted over 300,000 miles. Your driving habits and how closely you follow recommended maintenance procedures are the deciding factors. That is why it’s so important to get a good warranty.
Difficulty changing gears – Low or dirty transfer case fluid can affect your transmission’s ability to shift gears. It can also result in your car unexpectedly falling out of four-wheel drive. … This will create loud grinding noises which may become louder when four-wheel drive is engaged.
Transfer Case Replacement Cost – RepairPal Estimate. Labor costs are estimated between $438 and $552 while parts are priced at $2,063. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
Can a bad transfer case cause no reverse? If the transfer case fails during operation, the vehicle may be left permanently in neutral or the transfer case may bind. If the transfer case is malfunctioning electronically it can cause erratic shifts from high to low gear and from two-wheel drive to four-wheel drive.
Based on my understanding of how transfer cases work, there IS always power going THROUGH the transfer case, it just passes straight THROUGH from the input shaft to the rear output shaft without being transferred to the front output shaft.
Some Transfer Cases may exhibit a high pitched whine when first installed. This may be related to a speed sensor not installed properly and hitting the sensor tone wheel. Make sure all speed sensors are installed correctly and reading correctly.
A little loud, but not unusual. One piece cases are louder than the split cases. It doesn’t whine like a case low on oil. When you get low on oil, you’ll know.
Replacing the transfer case will take a couple of hours, and it’s a heavy part. It’s important to go in knowing exactly what to do and how to do it right. We have some tips for you: To remove the driveshafts, you may want box end wrenches.

A transfer case is part of the drive-train (this includes four-wheel drive, all wheel drive, and other multiple powered axle vehicles). Specifically, this mechanism shifts power from the transmission to the front and rear axles with the power of the drive shaft.
The transfer case is a mechanical component in all four-wheel-drive and all-wheel-drive vehicles. It distributes engine power from the transmission to the front and rear drive shafts, acting as a differential between the front and rear wheels.
An electrical fault such as a corroded wire or faulty 4WD dial/switch, A component failure such as a faulty transfer case module or actuator. A seized differential caused by poor lubrication. A leak in the vacuum hoses (older traditional 4WD systems)
How to Test: If you want to test your 4-wheel drive, then put your car into 4-wheel drive and then turn the front wheels, left and right, while driving in a tight circle at a very low speed. You should feel them bind up if 4wd is working.
No, the front driveshaft does not rotate in 2WD. In 2WD, the front shaft is disconnected from the transfer case and the front diff.
No you cant really bypass the transfer case, it must be there for mechanical and electrical reasons such as the speed sensor on the back.
If your car makes a humming noise, it could mean the differential needs lubricant, the transmission is failing or the universal joints or wheel bearings are wearing out. … Don’t let the noises continue without having an expert take a look at your vehicle.
