BMW 5 Series E39

1. Before work let's the car pass several kilometers to warm up lubricant liquid of differential, then the car and reliably establish to a poddomkratta it on support.
2 Place the drain capacity, rags, newspapers and a face key under the car. As lubricant liquid will be hotter, put on rubber gloves to prevent burns.
3 Remove a stopper of a bulk mouth from differential; it is top of two stoppers.

2. Turn out a stopper of a jellied mouth (1) a face key. Address an accompanying illustration.
5. If a small amount of oil, level normal pours out and RKPP is tight. Otherwise check a finger whether oil level reaches the lower edge.

At considerable leak of oil it is necessary to establish the reason and to eliminate it.

Having established capacity under differential, weaken a drain stopper (2); it is lower of two stoppers.

3. Carefully turn off a drain stopper, you will not remove it from a casing yet.
7 Let's all liquid flow down in drain capacity. The drain stopper is magnetized and attracts to itself metal shaving. Wipe shaving from a stopper. Wrap a stopper with a new sealing ring the moment of 50 Nanometers.
8 you stanovit a drain stopper and reliably tighten it.
9 Fill differential with lubricant liquid.

RKPP oil rather dense. Therefore do not fill in a lot of oil at once. Take a break and substitute capacity for collecting the poured oil.

10 Establish a bulk stopper with a new sealing ring and reliably tighten its moment 50 Nanometers.
11 Lower the car on the earth. Having passed the first several kilometers, check whether the drain stopper proceeds.
