New to forum but I bought a JD 4310 in 2002. Lately I've noticed when operating out of 4WD that in reverse particularly I hear a thunk as it were like a gear popping out though it does not pop out. It is however something you can feel but the tractor keeps moving. It is equipped with the ePowrReverser. It also has the electronic switch on the right side MFWD that lights when engaging 4WD if that means anything. Any idea as to what it is? I'm concerned that something is going to give way at some point and I'll be in a spot where I won't be able to move it. Thanks in advance.
