Reducer - Toyota 4Runner, 3.0L, 1995

So this is the first entry for Runner's summer season.

The chronology of events can float a little (both within one record, and within several of them), so I leave the dates and times current at the time of filling in the BZ.

Arriving on his vacation at the dacha, his father set about putting Ranner in order.

To begin with, he decided to add oil to the rear axle, which had long been written from under the oil seal. Topping up the oil showed that it was done on time, because there was not so much oil left there.

Actually, the oil seal did not start to write suddenly ... in the spring we changed the gearbox due to the fact that it began to hum. And the buzz is alarmingly loud.

An autopsy showed an unpleasant picture: the hum arose due to the breakage of a pair of teeth on the drive gear. By the time of replacement, we bought a BU bridge in good condition through forum contact from a like-minded Runnerovoda. The gearbox in that bridge turned out to be really in very good condition ... it seems that even the clutches of the LCD system were much more alive than ours, because the rotation of the axle shafts in different directions was a difficult task.

Having removed the old gearbox and installed the "new" gearbox, we began to enjoy the silence in the cabin, however ... the oil seal at the "new" gearbox was leaking.

Well ... flowing means changing. Ordered, bought. My father left at the end of his vacation in Moscow. Having decided that it was not an easy task to change the oil seal on his own, the father decided to entrust this business to specially trained people in the service. By God, it would have been better to do it yourself ... I don't know what service he chose for this, but ... no ... they changed the oil seal ... and it began to leak less ... actually now it only sweats a little (there was a depletion on the shaft neck, unfortunately, but at least it doesn't flow) ... But now the gearbox hums almost as before ... Why? Yes, because these, their mother, servicemen tightened the nut of the shank, as God will put it on their souls, without taking care of setting and adjusting the gap in the main pair. And father, as usual, sat down and went ... and not somewhere, but to our village 200 miles away ... In general, now it was too late for them to make claims ...
So now you need to adjust the main pair again. :about(

PS: a little later I will add a photo of the gearbox (unfortunately, I forgot to take a picture of it at the time of replacement), so stay tuned for the BZ.
