Things to Keep in Mind When Buying a New or Used BMW Transfer Case
BMWs are some of the best cars on the market, and for good reason. They are high-performance, reliable, and consistent. However, a failed transfer case can take the fun out of driving a BMW, and many drivers experience this problem each year. If you're in the market for a new or used transfer case, here are some things to keep in mind.
Disassembly of a bmw transfer case
BMW's remanufactured transfer case undergoes the same rigorous testing and quality control measures as new products. It undergoes thorough disassembly and cleaning to guarantee the best quality possible. Every part is checked for cracks, corrosion, and adherence to the original equipment specifications. If necessary, new parts are installed.
The transfer case is a vital part of your vehicle. If it malfunctions, you will be unable to drive your car. Its failure may be the cause of several other problems with your car. For instance, if your car makes grinding noises when shifting gears, it may be a sign of a failing transfer case.
In some instances, a transfer case actuator needs to be replaced, which can cost over $2000. The process of changing gears in a transfer case is time-consuming, but it can be accomplished by a competent DIYer. Another option is to buy a new transfer case actuator assembly, which costs $540. This way, you can avoid the hassle of rebuilding the entire system.
Fluid in a bmw transfer case
If you're considering purchasing a used BMW, you might be wondering about the type of fluid in the transfer case. There are several types of fluid used in the transfer case, including automatic transmission fluid, gear oil, and specialized fluids. All of these fluids keep internal parts clean and lubricated and prevent corrosion. Some people prefer to use original OEM fluids, but alternative brands are available that are cheaper.
If you're experiencing gear-shifting issues, you should look into the condition of the transfer case. A leak could mean a number of problems. For instance, you might have a faulty transfer case that can result in a malfunctioning transmission or other components. You'll also want to check for noises. Most BMWs have quiet engines, but if you're hearing a grinding sound while shifting gears, the transfer case could be failing.
Once you've identified the problem, you can replace the fluid in the transfer case. In order to do this, you need to remove the fill plug and drain the old fluid. You'll also need to replace the exhaust gasket and exhaust nuts. Afterward, you'll need to reinstall the underpanels.
Symptoms of a failing bmw transfer case
When it comes to identifying a failing BMW transfer case, you can look for three common symptoms. The first one is an intermittent clicking noise. This sound is usually caused by a low fluid level in the transfer case, and you can try to remedy the problem by changing the fluid in the transfer case. Another common symptom is a malfunctioning 4WD light.
Other symptoms include electrical issues. A malfunctioning transfer case control module can cause lights on the dashboard to flicker or stop functioning altogether. It may also cause the vehicle to have trouble starting. If you notice any of these signs, you should take your vehicle to a mechanic for an inspection. Before inspecting the car, make sure it is on a level surface, have the parking brake engaged, and disconnect the negative battery cable to avoid any electrical problems. The transfer case control module is located near the transfer case, and is relatively easy to spot.
Another symptom of a failing transfer case is grinding noises while shifting gears. You can detect these noises by listening to the engine. The noise will be accompanied by growling, humming, or grinding sounds. The car may also jerk when accelerating under full throttle. If you hear this noise, it is likely due to a failing BMW transfer case.
Cost to repair a bmw transfer case actuator
A failing transfer case actuator can ruin the performance of your BMW 4WD. The actuator contains a small plastic gear that wears down over time. A failing gear causes the transfer case to jerk and can even cause the brake and ABS lights to illuminate. Fortunately, the problem is relatively simple to fix. In just an afternoon, you can replace the gear and have your BMW 4WD running like new again.
The cost to repair a transfer case actuator will depend on the extent of the damage. Replacing the entire actuator will cost around $450, while replacing the ring and encoder motor will only cost between $30 and $60. If you're handy with tools, you can also replace the input seal for around $50.
While some transfer case assemblies fail before 50k miles, this is not common for those who maintain their vehicles. It's more likely to happen to people who abuse their vehicles. Typically, people will notice problems with shifting and other issues with the vehicle's transfer case after a few months, and will have warning lights and dash indicators that indicate the issue. Fortunately, many of these issues can be repaired, so you don't have to spend a lot of money on a replacement transfer case.
