I took mine in today for the popping and harsh downshift.
I was told that they retourqued everything but still had the popping so they are going to replace the leaf springs eventhough I told them it was heard near the front.
They told me that the leaf springs could transfer through to the front, I call BS.
I ask what did they do for the hard shifting and he said the leaf springs are causing that too, I call BS.
Either way they are replacing the leaf springs once they come in. Ill be honest I haven't had a hard down shift after I took it in.
