Just noticed I have the same clicking problem as described by these threads:
Distinct Drivetrain Clicking Noise
and
clicking sound at low speed?
Looks like the differential needs to be re-lubed and halfshafts need to be rotated or something. No idea what a nissan dealer will charge for that probably an arm and a leg. Good thing is this may be the reason my traction control kicks on randomly when accelerating spiritedly in a straight line.
If anyone has experience with this, how long can I wait before this causes major damage to my drivetrain? I'd rather not worry about solving this till 2021.
Edit: Will probably attempt a DIY diff fluid change before bringing it into a shop. Maybe that will solve the problem....
