How Much Does a T800 Cost?

Remember, the cost depends on factors like the age of the model, its intended application, and any existing problems.
Like with any other used model or truck that isn’t under warranty, it’s often recommended you get a pre-purchase inspection to get a better idea of the overall condition the vehicle is in, safety features, the condition of the electrical systems, and any shortcomings you should be aware of. It is suggested you consult with your local repair shop before biting the bullet.
Common Problems for the Kenworth T800 and Their Solutions
Now, let's get down to the nitty-gritty and tackle those common issues that can pop up in your T800 and how to deal with them like a pro.
#1 - Flickering Fog Lights
One of the most common Kenworth T800 issues is the fog lights not functioning as they should. This issue is often due to electrical wiring issues. However, before diving deep, it's wise to check the fuses and the bulb, just as you would with any other truck model. Sometimes, the solution to a problem can be as simple as a new bulb or a quick fuse swap!
#2 - Displacing Front Springs on Steer Axle
The front springs on the steer axle may sometimes displace and move apart from each other. The culprit here is often the thick, low-quality band used to hold them together. To remedy this, consider having a metal U-bracket welded on instead — this upgrade will ensure those front springs stay right where they belong, providing you with a smoother ride while avoiding any future mishaps.
#3 - Going In and Out of Cruise Control or High Idle
Does your truck have trouble staying in cruise control or at high idle? One possible cause is a seized-up clutch linkage. The solution? Replace the ball and socket in the clutch linkage. With a fresh ball and socket in place, your cruise control will be back in action, making those long-haul journeys a breeze.
#4 - Turn Signal or Brake Light Problems
Got Kenworth T800 turn signal problems? Are they playing a guessing game with the brake lights? The culprit might be corrosion in the chassis node. This issue is due to the chassis node's location underneath the truck, near the driveline, where mud and dirt love to gather and corrode electrical components and wiring.
Make sure you get your mechanic to properly clean the chassis node frequently, especially if you’re driving off-road.
