Ever since you got your driver’s license, you’ve been to told to check your engine oil. But what about the fluids underneath your vehicle? If you’ve got a rear-wheel...
For the better part of the twentieth century, nearly every vehicle on the road had the engine sending power to the rear wheels. This arrangement makes a lot of sense to designers, with the...
Gear, or differential, oil is used to lubricate the gears in a car’s transmission so that it can shift smoothly and easily. This type of fluid is generally used on standard transmissions,...
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...
On the drive wheels, which are the front wheels in your case, there will be some resistance to turning because of the connection to the transaxle through the CV axles. If it takes a lot of force though to rotate...
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...
The instructions for removing the rear differential assembly for your truck as follows: * Position the vehicle on a hoist (or jack stands) * Position a support under the axle assembly * Remove all the brake components * Remove the...
There were 14 different axle, ratio and rear brake combinations for those two years. 1997 and 2001 do not interchange. However, a quick look at the published interchange data suggests that IF the axle, ratio, and brake set up "matches",...
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, 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 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 - there are several possible sources of a differential fluid leak: the pinion seal, the axle flange seals, or the rear differential cover gasket. I recommend an oil leak inspection performed by a mobile, professional mechanic, such as one...
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...
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...
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...
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...
Jack up the vehicle and put it on jack stands with all 4 wheels off the ground. Then put the transfer case in 4WD and put the transmission in gear. Check the driveshaft on the rear and see if its...
Hello, thank you for writing in. Your vehicle is typically rear wheel drive, when you have it in 4-Hi then you are telling the front wheels to engage with the transmission. The fluid is then pressurized and the gears mesh...
Your 4WD will work until the pinion gear cracks or breaks due to the odd wear of the ring gear that has 4 broken teeth. First, recommend that you drain the fluid and fish out any broken metal and debris...
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...
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...
