Not related to a combat vehicle, of course, but...to help people...

The Rav4 has such a problem that after 70-120 thousand mileage the rear-wheel drive clutch bearing, also known as the viscous coupling bearing, begins to hum (our mileage is 95,000). An unpleasant low-frequency sound can already be heard at a speed of 20 km/h and the faster you drive, the higher its pitch; after 90 km/h it is no longer a hum, but a constant terrible metallic whistle! If you do not fix the problem right away, you can get into trouble with the rear axle gearbox assembly.

In the original RAV4 catalogs, you will not find the code for this bearing by VIN number, since according to the regulations, the officials change the entire electric clutch. But, you will find the clutch number...

Electric coupling 41303-42020 with a bearing width of 17 mm (before 2009) Electro coupling 41303-42021 with a bearing width of 13 mm (after 2009)

I advise you to check... In my case, here is the parsley: Electric coupling 41303-42021 with a bearing width of 13 mm.

So let's look at it... There is very little information about this... more precisely, it is there, but only in the form, I went to a service center and supposedly they did it for me for 15,000 rubles... In fact, there is nothing terrible there and everything is very serviceable... A little bit of ingenuity and no crookedness hands...Unscrew the 4 cardan nuts, drain the oil from the gearbox...Next, unscrew the 4 nuts securing the gearbox...and the 4 nuts securing the coupling to the gearbox...and carefully remove the clutch, it is sealed (factory)...so if not with your hands, then tap the rubber a little with a mallet... and voila, the muff is on the table...

Next (preferably with a press) we remove the core from the crankcase... and knock the bearing off of it and remove the oil seal... It is advisable not to damage the oil seal (it is very difficult to find in stock)

Symptoms of a problematic all-wheel drive clutch

1. Rumble

– at speeds in the range of 40-60 km/h there is extraneous noise, sometimes the noise is similar to the sound of a trolleybus, sometimes a howl/hum;
2. Impacts from the rear
- when starting from a stop, when moving backwards, at low speeds with the steering wheel turned - impacts occur;

Such symptoms indicate a problem with the all-wheel drive coupling.

If the problems described above occur, we recommend: immediately contacting a Technical Service Station.

Possible consequences in case of untimely repair:

• breaking of the bearing seat;
• breakage and wear of friction clutches;
• failure of the main coupling shaft;

Replacing the oil seal

Replacing an oil seal is much easier than performing the same operation on a bearing. The sequence of actions will be as follows:

• Drain the oil by first unscrewing the left plug, then the right one;
• Disconnect the cardan, having previously marked its location;
• Unscrew the two bolts with a 17mm wrench and loosen each support screw;
• Using a 12mm wrench, unscrew the 4 fastening bolts and then disassemble the housing. It is necessary to place a special container to collect the oil liquid;
• Disconnect the terminals from the rear side and remove the magnet;
• Thoroughly degrease the mechanism and wipe it dry.

Toyota/Lexus clutch repair

One of the weak points of the Toyota/Lexus family of cars is the rear-wheel drive coupling. The service life of a bearing in size 120-95-13 (cars from 2009 to the current year) is about 80-100 thousand km, while the service life of a bearing in size 120-95-17 (cars produced in 2006-2008) is 120 -200 thousand km. There are many reasons for bearing failure, the main reason is improper operation of the car , for example: lowering a boat into the water (water gets into the clutch bearing, it fails), long trips with the 4WD function, slipping in mud and slush - all these tests The all-wheel drive clutch is difficult to handle. Remember that the all-wheel drive coupling is just an assistant in urban operation and is not intended for harsh driving conditions.

We carry out repairs of all-wheel drive electric couplings on Toyota/Lexus vehicles, performing the following work:

1. Replacement of bearing in size 120-95-17 (Original); 2. Replacement of bearing size 120-95-13 (NTN/ISB); 3. Conversion of the coupling from bearing 120-95-13 to bearing 120-95-17, all components are original; 4. Replacing the boot of the large bearing; 5. Replacement of the shank oil seal; 6. Replacement of the shank bearing; 7. Replacement of drive seals; 8. Complete overhaul and maintenance of the all-wheel drive electric coupling;

Disassembling the Toyota front axle gearbox

In order to disassemble the gearbox on the front axle, you should perform the following sequence of actions (before starting work, the gearbox must be completely cleaned of dirt and installed on a workbench):

• Using a 10mm spanner, unscrew the 8 nuts that secure the cover in the front part to the gearbox housing;
• Remove the cover and gasket;
• Using a 10mm socket, unscrew the bolt securing the locking plate on the left cover and then remove it. The same should be done with the right plate;
• Using a 19mm socket, unscrew the four nuts securing the bearing caps to the differential box;
• Remove the left differential case bearing cover. To remove the right one, you need to screw a bolt into it; by pulling it, the cover can be easily removed;

Removal and disassembly of the driven gear and differential is performed in the same way as the rear gearbox. If there is oil leakage from under the crankcase cover in the lower part, you need to unscrew the 8 bolts securing it using a 10mm socket, remove the cover and the gasket under it, and replace the worn parts with new ones.
