Weird thunk noise when engaging clutch.
I've got a 03 rubicon I've had for about a month now. Not sure why I didn't notice it before I bought it, but I've got a weird thunk noise when disengage the clutch... mainly between 1-2-3 gears. If I let the pedal out real slow it's not there. Almost reminds me of auto lockers will suddenly engage or disengage.
I can also replicate the noise by letting it coast a little and then hitting the gas hard. So seems to be related to when torque is applied.
Shifts, really smooth other than that. Way better than my YJ did. Searching the interwebs seems like it could be a couple of things:
1. U joints going out.
2. Transmission, transfercase or motor mounts are lose or bad.
3. A bent fly wheel.
U joints look ok, there no slop or noise when I'm under it and try turning the rear driveshaft. When it's in gear I can turn it at all.
I know that the motor mounts are fairly new... look good from what I can see.
I can't see and obvious place underneath that it's hitting if something is loose under there.
Anyway, anybody experience something similar?
