8 Most Common Symptoms of a Bad Transfer Case

A transfer case is an important component in four wheel and all-wheel drive vehicles that splits the power from the engine to both axles. A bad transfer case can have a major impact on your vehicle’s performance, so it’s important to be aware of the signs that may indicate it needs attention. In this article, we take a look at eight common symptoms of a bad transfer case.

1. Loud Noises Coming From Under The Vehicle

One of the most obvious indicators that something is wrong with your vehicle’s powertrain is loud noises coming from beneath it when you accelerate or turn corners. If these sounds are coming from near where your transfer case is located then there’s likely an issue with it and you should have it checked out as soon as possible. It could be something as simple as low fluid levels or more serious such as an issue with internal gears or bearings.

2. Difficulty Shifting Into Four Wheel Drive

If you can’t seem to engage four wheel drive on your vehicle then it may also indicate something wrong with the transfer case. This could be anything from faulty shift linkage to an electrical problem or even actual mechanical damage within the unit itself. You’ll want to have this checked out by a professional mechanic for an accurate diagnosis and repair if needed.

3. Vibrations During Acceleration And When Turning Corners

Vibrations during acceleration and when turning corners can also indicate that there’s something amiss within your vehicle’s powertrain, including potentially its transfer case if applicable for your car model/type. This will usually require further investigation from a professional mechanic using specialized tools such as electronics scanners which can detect any issues through data readouts collected while driving or idle tests where they listen for any strange noises coming from different components in order to pinpoint what exactly might be causing them vibrations rather than just replacing parts blindly without being sure whether they are actually faulty or not..

4. Whining Or Squealing Sounds Underneath The Vehicle

Another symptom which can indicate potential problems with either transmission or even potentially its transfer case is whining/squealing noises coming from underneath while driving particularly when you accelerate hard over bumps in roads surface etc., These sounds usually indicate low fluid levels inside one of these components which must be addressed promptly before they cause further damage due too parts overheating due lack lubrication.

5. Leaking Fluid

If you spot any fluid leaking from underneath your vehicle then there’s a good chance it could be coming from either the transmission or transfer case. If the fluid is reddish in color and smells sweet then it could be transmission fluid, however if it’s darker in color and has a burnt smell to it then it’s more likely to be coming from the transfer case. In either case however, you should have your vehicle looked at by a professional as soon as possible to diagnose and repair the issue before any further damage is caused.

6. Unusual Movement Or Sluggishness When Shifting Gears

If you feel any unusual movement when shifting gears or your car seems sluggish when doing so then this can also indicate an issue with your vehicle’s transfer case, particularly its internal gearing being worn down or even broken in some cases depending on how severe the damage is. It’s important to have this checked out as soon as possible by a professional before any further damage is caused due too parts slipping out of place or even overheating due too lack of lubrication within them which can lead to catastrophic failures if not addressed promptly enough.

7. Difficulty Selecting Low Range Gear

If you’re having difficulty selecting low range gear on four wheel drive or all wheel drive vehicles (AWD) which use an additional gearbox known as “transfer case” in order for this purpose, then there may be something wrong with this component. This usually occurs due either electrical issues preventing the system from engaging low range gear correctly or mechanical issues such as broken parts inside them which require further investigation and possibly replacement depending on severity of them damages found upon inspection by qualified personnel equipped with relevant tools and diagnostic equipment capable of pinpointing faulty components easily enough so that they can replace only those instead replacing unnecessary parts just blindly without being sure whether they actually need replacing at all….

8. Clunking Noises When Shifting Into Gear

Lastly, another common symptom indicating problems within your car’s powertrain system which can include its transfer case is strange clunking noises when shifting into gear after having been stationary for some time prior (such as parking up). This usually indicates that either internal components are worn down/damaged or that one of linkage arms connecting shift lever inside cabin area with actual selector switch within transmission unit itself has become loose/worn down hence causing these strange noises when attempting engage certain gears after prolonged periods stationary due lack lubrication between their moving parts. It’s always best advised to have these issues inspected professionally so that they can diagnose fault more precisely than just replacing parts blindly without knowing exactly what needs repair first..


A transfer case is a key component in four wheel and all-wheel drive vehicles that splits the power from the engine to both axles. If your vehicle is exhibiting any one of these eight symptoms, then you might have a bad transfer case and you should have it checked out by a professional mechanic as soon as possible. Regular maintenance such as oil changes and inspections can help prolong the life of your transfer case and prevent more serious issues in the future. Additionally, if you also need to tow heavy loads on a regular basis, consider investing in good shocks for your F150 – read more about Best Shocks for Towing F150 article here on our website.
