Common 4WD Problems That Only a Professional Mechanic Can Spot
If you are a 4WD owner, it is important to stay on top of its performance and maintenance. When driving your 4WD for long enough, you learn about its workings and nuances. While it sounds corny, you become one with the machine and feel it immediately when something is “off”.
However, you might lack the technical knowledge, toolkit, or diagnostic methods to identify the problem correctly. This is where a professional mechanic comes into the picture. In this blog, we list common 4WD problems that only a professional mechanic can spot.
Timely intervention can save you a lot of effort, time, and money. These problems manifest in a much smaller scope before gradually worsening. Therefore, proactive action is the best chance against untimely breakdowns.
Transmission Issues
Transmission is what facilitates the smooth shifting of gears in a fourby. What sets 4WD apart from a normal car is its ability to explore tough terrains and carry heavy loads. This is obviously impossible without the impressive, durable transmission that 4x4s are known for.
Even the slightest issue with it negatively affects the driving experience. Overheating, dirty transmission fluid, worn clutch pads, and water ingress are common reasons behind transmission issues in 4WD.
Mechanics use advanced diagnostic tools to identify the right cause and find an appropriate solution. Slipping gears, delayed shifting, and vibrations are telltale signs of transmission issues.
If you notice any of these, it is highly recommended to book an appointment with a car mechanic in Gold Coast as soon as possible.
Transfer Case Problems
It is one of the most common problems plaguing 4WDs. A transfer case is a gearbox that splits power from the transmission to the front and rear axles. It does so with the help of drive shafts and is fitted to the back of the transmission.
Now, due to poor maintenance, overloading, or long-term use, a transfer case can face issues that prevent it from doing its job. Most common reasons include inadequate lubrication, mechanical wear, poor tyre condition, and electrical failures.
With the right diagnostic tools and equipment, 4WD mechanics accurately identify the problem and deal with it.
Structural Damage
While off-roading in your 4WD and exploring the uncharted territories is fun, you must practise caution. Structural damage is a common side effect of wandering off roads. Chassis cracks, suspension failures, bent frames, damaged underbody, and even worn internal components are structural damages that affect the 4WD's performance. Since most of the damages are hidden from sight, you need advice from a professional mechanic to make the right decisions. By investing in regular maintenance, you can prevent structural damage from being a roadblock to your expeditions.
Suspension Issues
Off-roading, towing, and carrying bull bars put stress on the 4WD’s suspension system. Now, the suspension system relies on components such as shocks, struts, control arms, and bushings for optimal performance. With time, any of them can be damaged due to wear and must be either repaired or replaced.
Without an accurate, flawless diagnosis from a professional mechanic, it is impossible to make the right fix. Here are a few things mechanics do to identify suspension issues.
-Check for shock absorber leaks
-Inspect bushings for cracks
-Look out for sagging springs
-Wheel alignment checks
Differential Issues
Differentials allow front and rear axles of 4WDs to function at different speeds. This is the key factor that allows a four-by to navigate challenging terrains. However, due to water ingress, mud accumulation, and fluid contamination due to seal damage, differential issues affect 4WD performance. Noises such as whining, humming, and clunking are signs of damaged differentials. Moreover, excessive bumpiness and vibrations are also telltale signs to look out for.
