Reverse Noise

New 2014 Sunseeker 2690s, Ford chassis.

Have 3 trips on it, 1,900 miles on it.

Several times when backing it up, there is a scrapping, almost like brakes not disengaging, noise no hesitation, or grabbing, just scrapping/scrubbing noise (resonates inside & all).

Does not sound like transmission, but in rear wheels.

It is not every time, but several of the times backing it up.

Anyone experience this?

Thanks,
Markiemark

On our Solera, I was concerned about noise in reverse until I figured out I was hearing sound through the backup camera.

Do you have mud flaps?

x2 When you shift into reverse, the backup camera audio comes on. If set loud enough you can hear a bird chirp that you will think it is perched on your seat.

It is not the camera or audio, unless the system has speaker located in the duel rear wheel system & it is playing a crazy trick on us; at least I don't think it is the camera audio.

Yes, there are mud-flaps (and the noise very much sounds like a mud-flap scrapping potentially) although one time when hearing the noise I tried checking them and they appear a ways away from the tires.

One time, wife was backing into site, I caould hear it outside down by the rear wheels.


Something is scrapping, rubbing, or binding ---when in reverse, and not every time, plus no noise forward?!?!?!?!

Thanks,
MArkiemark

Try rolling the flaps up with a bungee cord and try it.

Moisture ?

Does it happen only after sitting a day or to?
Maybe after a rain?
Does it go away after driving a bit?
Moisture or rain will sometimes make a light coat of rust
on the brakes which wears off right away, but does not cause a problem.
If so it may be normal.

Yes, after sitting or stored a week or so. and yes been a high moisture winter.

What is baffling, is that the rub/scrub sound is sometimes present after a longer drive to campsite (so brakes have been used), and then when backing in, the sound is there & definitely noticeable, just in reverse

Have not found a definite pattern yet, and when it has happened, it was backing in a site, minimal reversing, so I did not play around with it, still getting to know the unit.

On the mudflaps, they are pretty stiff, with a brace keeping them from rubbing back of tire, from what I can see, so bungey'ing them would not make a difference.

Thanks,
Markiemark

I think it's possible that it's rust from the rotors. When driving forward it applies more pressure to the front calipers. When you back up, it might be picking up the surface rust from the rear. I'd try backing up and hitting the brakes a few times. If it goes away, I wouldn't worry about it. If it continues, have it looked at.
