How to Remove the Oil Seal on the Sunny's Drive Shaft?
2 Answers
The Sunny's drive shaft does not have an oil seal. The oil seal that needs to be removed is located at the connection between the transmission and the engine. The removal method is as follows: 1. The transmission and engine need to be removed together; 2. Then separate the transmission and engine; 3. Remove the torque converter and then take off the oil seal. The components of the drive shaft are as follows: 1. Universal joint: This is an important component of the drive shaft. In rear-wheel-drive vehicles, the engine, clutch, and transmission are installed as a unit on the frame, while the drive axle is connected to the frame via elastic suspension. There is a distance between them that needs to be bridged; 2. Telescopic sleeve: This involves welding the spline sleeve and the flange yoke together, and welding the spline shaft to the drive shaft tube. The new type of drive shaft changes the traditional structure by welding the spline sleeve and the drive shaft tube into one piece, and integrating the spline shaft with the flange yoke; 3. Shaft sleeve: This helps reduce friction and wear during shaft movement. Its basic function is similar to that of a bearing, but it is relatively cheaper. However, due to higher friction resistance, it is only used in certain parts.
I've replaced quite a few drive shaft oil seals on cars, and today let's talk about the Nissan Sylphy. First step is ensuring safety: use a jack to lift the vehicle and securely place jack stands to prevent slipping and injuries. Next, remove the wheel to expose the drive shaft section. When loosening the drive shaft nut, make sure to use the correct size wrench - the Sylphy usually requires a 19mm one. After removing the drive shaft, you'll see that small ring-shaped oil seal, which may have cracked due to aging. Carefully pry out the old seal using a dedicated seal puller or screwdriver, being careful not to scratch the shaft neck, otherwise the new seal might leak. Before installing the new seal, clean the shaft end and apply some grease to aid sealing, then gently press it into position. After reassembling the drive shaft and wheel, take a short test drive to check for any abnormal noises or oil leaks. The whole process takes about two hours - beginners might easily lose screws, so it's advisable to prepare spare parts in advance. Regular inspection of oil seals can prevent major issues - don't wait until there's severe leakage to take action.
