I m Nissan Liwei, the car transmission gurgling, stepping on the clutch and not ringing, there is no

Hello, generally start the car with abnormal noise, step on the clutch there is no sound, this situation has 1, clutch release bearing wear. 2. The bearing of one shaft of the gearbox is worn. The specific reason needs to be disassembled, inspected and replaced.

Hello, this may be a problem with the release bearing or a problem with the clutch plate and pressure plate, go and check it.

If this is the case for you, it is recommended to focus on checking the wear and tear of the gears inside the transmission, and it is best to replace the transmission fluid.

According to your description, it should be one shaft, that is, the input shaft of the transmission, and the bearing is squeaky.

If the abnormal noise disappears after the hot car, don't worry about it, it's cold and oily.

If there is an abnormal sound after the hot car, and the mileage runs more, try to change the transmission oil first, and there is still an abnormal sound after the change, that is, the bearing is faulty.

Hello to tell you about this situation, you should be the gearbox of the release bearing of the problem, it is recommended to go to the 4S shop to check.

Hello, this Nissan Liwei is a common problem of this car, and it is useless for some people to replace the separation bearing, and it does not affect the use.

You can try changing the gear oil first.

There may be some reasons why the gearbox has an abnormal ringing sound:

1 Wear and damage of the bearing When the bearing is worn, its clearance will increase, and the fitting accuracy will decreaseWhen the bearing is damaged, abnormal sound will be generated because the bearing cannot operate normally, and even cause damage to the transmission element in the gearbox, resulting in the expansion of the fault

2. The wear of the transmission element or the low accuracy of the parts selected during the replacement, such as the wear of the gear or the matching gap between the replacement of the new gear and the original gear is too large

3. Poor lubrication caused by insufficient lubricating oil or excessive lubricating oil This is to replace the corresponding lubricating oil (grease), otherwise it will aggravate the wear of the gearbox and shorten the service life

4 The bolts of the gearbox shell (end cover) are loose The bolts are loosened by vibration during use, and they should be checked regularly

1. When playing the direction, the steering power pump becomes the load of the engine, it may be that the resistance of the power pump is too large, and the air intake is reduced quietly or the idle control valve is blocked, resulting in a decrease in engine idling. This seems to be a common problem with old Nissan cars, and cleaning the throttle should help somewhat. As for the replacement of the booster pump, you can see if there is a problem with the bearing of the booster pump, if it is confirmed that it is a booster pump problem after the exclusion, due to the high cost of maintenance and replacement, it is not recommended to replace it, or find an old part to try it, or use it alive.

2. Clutch problems. The situation that LZ said may still be a little vague, is it difficult to step on the clutch, or is it difficult to hook up in 1st gear? It stands to reason that if the other gears shift normally, you can basically rule out the problem of the clutch itself, if it is a pure regret that the 1st gear is difficult to hang, it may be a problem with the synchronizer of the 1st gear in the gearbox, try the "two-foot clutch" method will not be better to hang the gear.

If it is a synchronizer problem, it is also troublesome to repair, and it is not recommended to repair it.
