Hey everyone,
So we are half way through our Florida road trip. Pathy has performed very well. 3200km on the way down, and I spent about $375 on fuel. But we were sporting speeds well above 80mph so I am happy with it.
Now we are in Kissimmee. Noticed the other night that there is a whine at idle when hot. However, if I shut down and restart, the whine is gone. Weird.
So some possibilities :
Alternator, but I just replaced it last summer, and it's not acting up from a charging perspective.
Power steering, but there is no change to the noise if I turn the steering wheel.
Could be belt tensioner pulley, but why would the noise go away on shutdown?
AC compressor?
Also, some drivetrain vibrations I'm noticing. Only apparent on throttle and disappears off throttle, seems to be coming from rear end, but vibrations can be funny that way. I did check front diff before leaving, but the rear diff check/fill port was seized. No evidence of leak or other issues so we left it. Any ideas on this one? Was thinking anything from u joints to worn pinion gear. Or transmission?
