Hi everybody,
I have one doubt that is really gonna drive me crazy.
As my forma mentis imposes me, I will try to be as clear as possible - also because English is not my mother tongue - and with the risk of becoming boring. I will accept it.
Since the beginning of my ownership of my Toy (which has a 6speed manual gearbox, with low gear insertable without locking the center diff) I can hear a sort of noise (more or less like a knock, or hit) coming from the driveline when: a)transiting from gas-pedal released to acceleration; b) passing from R to 1st gear or from one gear to the other
Might be a sensation , but I feel that this phenomenon comes more evident when the driveline is somewhat hot.
I do not use my Toy to tow anything and neither I have ever used it with the central differential locked on the asphalt, but only in some passages in snow/glawed ice on the road or steep inconsistent ground (gravel).
I have already bringed the car to a mechanics, with the result that "this is quite normal, and if you change gear gently the phenomenon almost cannot be perceived. Anyway, this is because this is a real full-time 4WD, and some backlash is voluntarily given to the driveline".
Notwithstanding this, I have made a visual control being under the vehicle, while another person was very slowly passing from the R to the 1st and vice versa, moving on a plane asphalt for not more than half a meter forward and backward. Briefly, the result is that when inversing the gear and the motion of the Toy, the front shaft exiting the central differential turns a little with respect to the back shaft exiting the diff, that for a moment rests motionless. Vice-versa inverting the motion of the vehicle.
At this point, my question is:
a) is there anyone of you with the same phenomenon? And if yes, do you consider it overall normal?
b) on the contrary, if it a symptom of something going wrong, what has been the cause for you.
I really thank you in advance and I look forward to hear a response.
