Default diff moan/groan......

hey guys, well, just hit 500 miles today. probably figuring what i'm dealing with is the regular sounds that come from the diff. i noticed it at 20 miles, and is still there. when taking turns at very low speeds(1-4mph), on the gas, i get the very low groan/moan. its not very loud. i used to have a similiar sound on my old ap1, but it almost completely went away after i put in le607. just want to hear back from you guys, i'm not worried about it, just want to see what some ap2 owners, perferrably 06 owners have heard. thanks!!!

pete

also, there are no other sounds except when turning(going straight, reverse, etc.)

I am not sure if it's the same thing but I have a moan from the rear right (could be the diff) at around 73 mph but it's tolerable. Had honda tech listen to it and said it was normal resonance.

Nothing changed when I put in le607 here.

You mean a sound when you are making turns in the parking lot? I had that too. I ended up getting a new diff swapped out.

I would take it to the dealer and have them note the noise. Even if they say 'nothing wrong', it will be on record. If you have a problem with the diff in the future, you will have a better case to get it replaced (sometimes they won't replace under warranty because they cry abuse).

when taking turns at very low speeds(1-4mph), on the gas, i get the very low groan/moan. its not very loud.
IMO thats very normal too
During those situations the Torsen diff is working hard.

thanks so much for the replies guys! i'm not freaking over it, but if it gets louder over the next 1k miles, i'm gonna go in. i'm figuring it wont, like stated above, the lsd works the most in hard turns. and by the way at 530 miles today

Inside wheel is rotating less than the outside wheel, the torsen differential senses this and compensates, that is the sound you hear.
