I cant believe that you currently have an electric vehicle and are willing to junk it for only a $500 repair.... I bet you that if you change the transmission fluid and put in a little bottle of "Prolong", it car will continue to run... Especially since the transmission is only a 1 speed diff....Valdemar wrote: ↑Fri Jul 19, 2019 11:10 pmI guess it won't hurt to change it, sounds like an easy enough job. I'm at a point where a need to spend $500 on the car will be enough of a reason to send it to junkers. The dealer couldn't pinpoint the exact location of the noise, but given the nature of it I'd be very surprised if it is not the gear. I have heard noisy diffs, it is similar.LeftieBiker wrote:Once you are sure it's the reduction gears, you could try an additive with extra moly, or whatever they use these days to cushion mating gear surfaces - if you can find one compatible with the recommended (fresh!) oil. The good news is you can likely find a used assembly in good shape. I don't know what the Leaf reduction/differential setup looks like: is the motor mated right to it...?Valdemar wrote:I'm at 156k miles and there's now noise seemingly coming from the gear. It started as a faint gear like clatter at low speeds a while back, but now I can hear it on the freeway when the motor sends torque to the wheels, its kind of an odd noise like a quiet ICE engine running. Gear oil never changed. I'm guessing too late now, huh? Dealer once confirmed the noise was coming from the motor/gear area.
