When rolling backwards, either in gear or neutral just rolling my car makes a extremely loud moaning sound. It sounds like there is a Wookie from star wars trapped under my car making all types of god awful noises.

When going backwards these things seem to affect it:
-If I hit the brakes sometimes it goes away and sometimes it just changes the sound(louder or changes the pitch)
-when I am turning while backing up it seems to get louder and happen more often
-sometimes its a pulsing sound

I allready looked at the pads quickly without taking the wheel off and they still have lots of pad left so anyone have any idea what I am talking about???

Hooch'n

normal

I call thay my reverse Wookie, and it's Normal.

I get screaming not moaning when i try to go in the back way ....

Oh... miss read... my bad

LMAO! I was thinking the same thing at first

People can hear it from like 15 feet away and they stare at me like im some sort of freak that ran over Sloth from the Goonies and you tell me that this is normal?

ROFLMFAO!!!!! WOOKIE LOL. omg that was funny. Ive never heard it before

You might have a grooved rotor or stuck pad.. Time for a brake job?

Yeah, it really depends whose butt your throwing your hog into: some scream, some moan. It's normal.

HAHAHA me too..LMAO....oh man that was a good one ...LOL...

Try hitting VTEC in reverse and see if you can still hear the noise at VTEC

I hate to bring a thread back from the dead, but mine have been doing this *slightly* ever since I replaced my stock pads with the Hawk HP+'s. It is coming from the back brakes, I'm positive. So then I decided to take the rears off and put them back on to make sure I didn't do anything wrong. I over torqued the caliper bolts (maybe more so then before) via some incorrect info from another HT thread (but all is forgiven) and now I want to do it over again to make sure it's done right.

Is there anything else this might be? It can't be normal - it wasn't doing it before the new pads and hasn't ever done it on any other Honda I've had. And yeah, hahaha, it sounds like I've just run over a wookie.... moooooooooooan!

-Ben, who's going to Sears to get a smaller, more managable torque wrench, and hopes someone might have some advice when he gets back.

When I reverse the car goes right into vtec

Question

Why does my manual transmission car make a loud whirring noise in reverse?

Answer



Manual transmissions use mostly helical gears, but reverse is a special situation that requires a different type of gear - a spur gear.
The gears that make up the forward gear ratios are all helical gears. The teeth on helical gears are cut at an angle to the face of the gear. When two teeth on a helical gear system engage, the contact starts at one end of the tooth and gradually spreads as the gears rotate, until the two teeth are in full engagement. This gradual engagement makes helical gears operate much more smoothly and quietly than spur gears. Also, because of the angle of the gear teeth, more teeth are in engagement at any one time, this spreads the load out more, and reduces stresses.

The only problem with helical gears is that it is hard to slide them in and out of engagement with each other. On a manual transmission the forward gears stay engaged with each other at all times, and collars that are controlled by the shift stick lock different gears to the output shaft (see How Manual Transmissions Work for details). The reverse gear on your manual transmission uses an idler gear (the large spur gear visible at the right side of the picture below), which has to slide into mesh with two other spur gears at the same time in order to reverse the direction of rotation.


Most of the gears in a manual transmission have helical teeth. The three gears that make up reverse have straight teeth. The large spur gear on the right slides up to put the car in reverse.


Spur gears, which have straight teeth, slide into engagement much more easily than helical gears, so the three gears used for reverse are spur gears.

Each time a gear tooth engages on a spur gear, the teeth collide instead of gently sliding into contact as they do on helical gears. This impact makes a lot of noise and also increases the stresses on the gear teeth. When you hear a loud, whirring noise from your car in reverse, what you are hearing is the sound of the spur gear teeth clacking against one another!

Um, a MOAN.... not a WHIRL. While that is an interesting explanation of why the whirling sound is made (or as I equate it to the sound an RC car makes) that's not at all what I'm talking about, and I'm pretty sure that's not what ReBornGSR was talking about either. When I say moan, I mean MOAN. I keep imagining in my head the sound that two smooth metal pipes would make drug across each other. It is a deep and low sound, almost like when you hear a semi-truck braking. And that's why I keep thinking it is a result of something I did wrong installing the Hawk pads. Normal braking is fine, actually it's terriffic thanks to the pads, but that reverse sound is bad.

Unfortunately Sears was out of the torque wrench I was looking for, and though I could probably get my big one (heh) under there, I don't have a long 1/2inch extension that I need to clear one of the caliper parts, and long story short, I didn't go ahead and buy one because I know someone that kindly bought me one as a stocking stuffer for Christmas, haha. So yeah, anyway... guess I'll just have to wait and see.

I think we have the exact same sound so I'm not going crazy here. I still haven't fixed it or been able to find out what it is. It happend shortly after I did a brake install so I guess we screwed something up along the way
The ladies think wookie noises are sexy
