Why does my Hyundai Terracan have a leak?

Why does my Hyundai Terracan have a leak?

A leaking diaphragm on the Hyundai Terracan’s front axle ‘Centre Axle Disconnect’ actuator could cause exhaust gas recirculation (EGR) diagnostic trouble codes (DTCs) to be logged. Since the EGR valve was operated by a vacuum, leaks elsewhere in the system could affect its performance. Hyundai HP Terracan: shudder from rear differential

Can a limited slip diff be changed on a hp Terracan?

This may be rectified by changing the diff oil (Mobil limited slip diff oil was recommended), though it could take up to 1500 km after the oil change to eliminate the shudder. If the shudder was not rectified by changing the diff oil, then the limited slip diff assembly (and two side bearings) would have to be replaced.

What causes an oil leak in the rear differential?

This might be the effect but not might not necessarily be the cause of the problem. There are several quick checks you can do to see what the problem might be. For the rear differential pinion seal, which seals the input flange (connecting to the rear propshaft) from the diff internals, there is a possibility that the bearing is on its way out.

How does the rear differential pinion seal work?

For the rear differential pinion seal, which seals the input flange (connecting to the rear propshaft) from the diff internals, there is a possibility that the bearing is on its way out. This is easily checked by shaking the propshaft in all directions.

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.

What kind of oil is leaking from my rear differential?

You will find grayish or light brown oil under the backside of your vehicle. The leak could be on the rear differential cover, the axle seals, or the pinion seal. How to stop it and bring the vehicle to the normal running condition?

What does a leak in the differential look like?

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.

Where are the seals on a rear differential?

Some differentials put these seals just outside the bearings, while others have the seals all the way at the end of the axle tube. Due to different designs, your differential can leak from many different places making it difficult to determine the exact leak location. However, many people find that rear differential leaks are the most common.
