What causes front wheel bearings to leak on Freightliner?
It is a sealed system, so if the level goes down, FIND THE LEAK. If the inner seal leaks, it will contaminate the brakes. If outer, it will show radial streaks from hub out onto the wheel and tire. My last maintenance checkup at Freightliner revealed a right front seal leak.
Is the oil in my front wheel bearings OK?
The oil level in both front wheel hubs is ever so slightly below the max fill mark. The oil looks “OK” as it still has the dark green tinge of new oil. There are no oil leaks from the hub. My motorhome now has a total of 14,000 miles of use.
What happens if you remove a wheel bearing?
Always follow wheel torque recommendations. Excessive or inadequate wheel torque can lead to failure of the wheel mounting system and loss of a wheel. Do not remove the outer bearing once it has been installed on the spindle. Removing it could cause the seal to become misaligned and lead to a seal failure or loss of a wheel.
How to change the oil in a Freightliner?
Be prepared to wait as the oil will take a long time to drain out 90+ weight oil is slow. on the other hand it takes some time to be sure you have the hubs full when adding oil. Fill it to the line,put the plug back in, rotate the tire a few times. now wait 30 min and re check the oil. I will bet it is low.
What does it mean when you have a differential leak?
A differential is a component found in the drivetrain of SUVs and heavy-duty vehicles. Whether the vehicle is a rear-wheel or all-wheel drive, finding leaked fluid in the rear of it indicates a differential leak. The fluid looks like motor oil but has a distinct smell.
How often should you change oil in a Freightliner?
Since oil volume is so small, one quart will change it a couple of times. So, either way is fine. But EVERYONE needs to keep an occasional eye on fluid level. It is a sealed system, so if the level goes down, FIND THE LEAK. If the inner seal leaks, it will contaminate the brakes.
Can a pinion seal cause a differential leak?
Another differential leak could be at the pinion seal. There is a yoke at the front side of the differential, and the surrounding seal can wear out over time. In order to replace the seal, you have to dislodge the yoke and pry out the seal. After that, place a new seal and then attach the yoke to its components.
