Default Click Sound from Rear in Reverse

Hi guys,

Every now and then, when I move from reverse to forward or forward to reverse, there would be a minor click sound. Sometimes there may be one click followed by another click very fast. But then if I pause/stop and resume reversing, the clicks do not reappear.

That sound also can be recreated if drive normally at around 2,000+ rpm and then suddenly let go off of the gas. This sudden stop in acceleration will jolt the car slightly and can create that sound.


I thought this was axle pop that was described in TSB Number 011217, and so I took it to the dealers to see. However, the inspector just said that it was my brake pads rubbing against my aftermarket rotors that was causing the sound. He said that it was normal.

I just wanted to get your opinions on it. Was the Honda guy correct?



Cheers,
Thomas

My brakes do that, i thought it was my axle nuts, but i had them retorqued to the 200-something lbs the tsb stated. It was still making the noise the same day.
Try moving slowly in reverse and then into 1st without touch the brakes, listen to hear if theres any noise. I only get it when i tap the brakes.

are you referring to a click/noise when you start releasing the clutch? It almost seems like drivetrain slack or something?

From the sticky -

Problem: Clicking noise from rear when moving in first gear or reverse. Sounds like two metal marbles.
Solution: Honda use to torque the axle nuts to 180 lbs. The correct torque is now 230 lbs. Torque your axle nuts.

So let's say I'm rolling forward from the momentum of first gear and need to reverse back. I would pop the gear out of first and into reverse. When I start releasing the clutch pedal and applying gas to move, sometimes a click noise would occur.

Yeah, I went to the dealers for that specific torque but they wouldn't do it, because they said that the clicking sound isn't the same as the TSB.
That's why I was a bit confused, since I thought I had that problem.

Thanks for the link though

It's important to stop fully before reversing. But yeah I get that noise at times as well. I thought it was some play in the cvs or something.

There are 10s of threads about various drivetrain clicks, but I’ll try this one. Did OP ever figure this out? Anyone with a similar sound know what’s making it? I know sound travels, and the car is moving, etc. But it really doesn’t come from the area of the rear bearings.

I had this same issue. Ballade diagnosed it as wheel bearings, which I replaced and the clicking sound went away.
