Greetings:
I have a client, with a 2011 Renault Master Model, Box PK6, which has a problem that cannot be solved, and it has me quite baffled. The entire differential area was repaired, changing all the pieces (a specialist in boxes repaired), and from that moment, the vehicle has broken 3 semi -axes on the left side, with a duration period of 2 months each. What is broken, are the stretch marks that enter the differential, and when taking out the broken half, gives the feeling that it would have been working dry, without cash lubricating oil. The box, of course, has 1 quality oil to the proper level. What can be failing? Of course, thank you very much for your comments!
