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,...
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...
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...
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, 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...
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 - 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...
If you are getting a leak from the side tube housing where it goes into the center differential housing then you will need to have the differential replace as an assembly since side tubes are pressed on and sealed from...
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...
