A diagnostic is only meaningful if there is a specific identification of a part or parts that have failed, are worn out, defective or the like. The bearings in the differential that you refer to are not visible for inspection,...

If you are getting a noise from the rear end when you put pressure on it by giving it gas then the cause is going to be the ring and pinion bearings most likely. Have the pinion bearing checked where...

In my experience, I have never observed the differential to be the cause of vibration. The most likely culprits are the wheel or tire, driveshaft, or axle. You had the wheels balanced, so that will rule out balance or a...

Sounds like you need to take it back to the shop where you had it changed. First you want to be sure it has enough of the correct oil. If it turns out it is properly filled, it may be...

Hello. Depending on where the leak is coming from, this will determine what needs to be done. If it is coming from the front pinion seal, then it may be the pinion bearing. This is a common failure on this...

Hello. A rear differential leak is something that requires immediate attention. If the fluid continues to leak, it could cause the gears inside the differential to start rubbing metal to metal. This will cause premature failure of the differential. It...

Hi there. Set the parking brake and set a wheel chock in front and behind the front wheels. Then put the transmission in drive and look under the vehicle to see if the rear driveshaft is turning. If the driveshaft...

Hello, thank you for writing in. If the sound is not coming from the differential, but is coming from that area, you will want to check the driveline and the axles. Look for anything that is rubbing, has a worn...

Hello, thank you for writing in. Issues like this can be difficult to locate, because you need the vehicle to be under a similar load to recreate the noise. With that being said, you may have a vacuum issue causing...

If you replaced the tail shaft seal behind the yoke and had to remove the driveshaft, then it is possible that the transmission vehicle speed sensor VSS is not installed correctly or the harness has been damaged. This will make...

If your transfer case can switch from 2 HI, 4 Hi, and 4 LOW, then there is nothing wrong with the transfer case. There seems to be an issue with the front locking solenoid and it may be stuck in...

The time depends on whether you are dropping in a pre-assembled (re-built or used) axle/differential or are talking about re-building what you have. To just remove and re-install the entire assembly would require roughly 7 to 11 hours depending on...

Hello - "the assembly needs to be changed" seems a bit extreme for a fluid leak. I recommend an oil leak inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose...

Disconnect the vent tube on the differential and blow through the tube on the differential. If you are unable to blow through it, then the differential is creating too much pressure and pushing out the oil through the tube. I...

Hi there - unfortunately, this is not a service YourMechanic.com offers at this time. Thanks for thinking of us though!

If a bearing in the differential has failed, the differential has to be opened up and rebuilt or replaced. You just want to make sure that the noise is not from a failed wheel bearing because if you have a...

Hello, I would not recommend to use transmission fluid for the differential. Yes, Acura did use a transmission fluid for the rear differential originally called Z1 but a new fluid (DW1) was formulated and Z1 production ceased. However the fluid...

If you are referring to the CV axle seal that is within the side case of the transaxle (i.e., transmission fluid is leaking), the service to request to get that leak repaired is axle shaft seal replacement. It is a...

Hello - your Tiguan is equipped with a Haldex torque-sensing system which directs power thru the differential to the axle (left/right) which has the best traction. Think of the differential as the reduction gears and axle(s) drive, and the Haldex...
