Signs That The Transfer Case In Your Truck Is In Need Of Service Or Repair

If you own a truck with four-wheel drive in it, you may find that the transfer case acts up from time to time. This is not uncommon, but some things may indicate the need to take your truck in for 4x4 transfer case repair or service.

Manual Transfer Cases

If the transfer case in your truck is a manual case that requires you to pull the shifter to engage four-wheel drive, the system is often simpler to work on, but 4x4 transfer case repairs can still be complicated. Inside the case, there are several gear sets that move to engage other gears. If the gears are damaged or the rails that they slide on are bent, it can be challenging to get the gear sets to mesh, and often they will grind or not lock together at all. 

To fix the problem, a 4x4 transfer case repair shop or a transmission shop that is familiar with transfer cases will need to remove the case from the truck and take it apart to replace the damaged parts. It can be a big job, and the tech needs to know what they are doing or the case can be damaged more during the repair. 

Typically bent shift rails or damaged gears result from overaggressive shifting or trying to shift the case while the truck is moving. While some cases can handle shifting on the fly, check the owner's manual for transfer case shifting procedures for your truck to avoid this kind of damage to the transfer case. 

Electronic Transfer Cases

Many modern trucks and SUVs are fitted with electronically shifted transfer cases that use sensors to determine when the right time to engage the four-wheel drive is. To shift into four-wheel drive, you push a button on the dash, and the system then times the movement of the gears to smoothly shift them into place to engage the four-wheel drive in the truck. 

While these systems work well, they can also stop working if a part fails inside the case or if some electronics in the system stop working. A bad sensor is all it takes for these electronic transfer cases to fail, but a local 4x4 transfer case repair shop or your local transmission shop can test the sensors to determine if that is the cause of the problem. 

If the 4x4 transfer case repair shop can't fix it, you may need to take the truck to your local dealership and have the service department diagnose and repair the transfer case for you. The truck will often need to be connected to a diagnostic computer to determine which sensor is causing the issue, and once the tech finds the problem, they can replace the sensor quickly and easily.

Servicing Your Four Wheels and More

When you think about it, cars are pretty complex machines. Their engines have to generate enough power to propel a few thousand pounds of material down a highway. They need to be comfortable inside, and they need to glide along smoothly on their rubber tires. In order to maintain this top function, your car will need some care from time to time. This includes basic maintenance like oil changes, and it also includes larger repairs, like changing the timing belt. Thankfully, we have auto service shops to do this work for us. In an expression of gratitude towards them, we started this blog.
