I took my Leaf in for the clunk and I don't know if it's been resolved or not. The dealership's response was that the lug nuts weren't tight enough. The service writer gave me a TSB printout showing that the lug nuts need to be at 83 ft/lbs. That torque setting is exactly what the hard copy owner's manual calls for. I used a torque wrench when mounting my winter wheels and I used the 83 ft/lbs. If the clunk is really gone then A) why wasn't it present on all four wheels, B) I need to calibrate my torque wrench, C) next time I'll just use 90.
UPDATE: I drove on some rough dirt roads at low speed. The clunk is NOT gone.
I took the Leaf in for the third time to try and resolve the clunk when hitting bumps. I thought the dealership was going to take care of it but they ended up not addressing it, saying that a brand new Leaf on the lot does the same thing. I discussed this with the service manager and got nowhere.
To reiterate, my clunk sounds like it is coming from the passenger front suspension. It clunks only on bumps and does it without regard to the position of the steering wheel. The issue is there when the car is going left, straight and right. The sound was there with both my winter and summer sets of wheels/tires/sensors.
The first excuse was that it was the lug nuts. The second excuse was that it was a rock behind the brake rotor shield. Now the excuse is that all Leafs do it.
