My Honda 2004 CR-V develops a howling noise from the rear of the car after about 20 miles of driving. I have changed the rear differential fluid, and burnished the differential clutches per Honda Service Bulletin 07-024, twice. It is quiet until it seems everything gets warmed up. Tires and brakes are good with recent service. What is this noise? Thanks to all

That could be anything from tires to differential or even a driveshaft carrier bearing on your Vette. The best thing to do is to see if it will make the noise while running it on a lift. If it does not, then the noise is most likely tire-related. If it does, then you can use a mechanic's stethescope to determine the source of the noise.

If the noise occurs when taking a tight turn change the rear differential fluid, I own a 2001 CRV and had a noise so I changed out the fluid and the noise went away. Your description does not describe the noise in detail so I am giving you the answer which solve my issue I hope this helps.

this is a very common problem for the honda cr-v. all it is, is the rear differential fluid. change the fluid- (use honda genuine rear diff fluid) then drive the vehicle in several figure 8 turns and the noise will go away.- note you only need 2 quarts diff fluid for a drain and fill.- hope this helps

No. Contaminated rear diff fluid causes this noise while making sharp turns. By changing your service interval to every 15k miles will keep the noise under control.

yes that is very normal. some people change it every 15k or 30k or when it makes noise. i would reccommend change it every 30 thousand but use only honda fluid

Hello! This could be from a few things - you could have a differential pinion gear that is misaligned and that will cause a howling noise - or it could also be a wheel bearing. Check your differential fluid and it might be worthwhile changing it.

Hope this helps and good luck!

have the rear differential and rear axle checked.

well, differential repair can be costly but, the dealership will cost the most to be honest. about around $1200 at the least.

did u use honda fluid and honda friction modifier if not diff will make funny noises worse when turning at a slower pace

Did you check your Transmission fluid and your differential fluids make sure there up and I don't know if you checked your rear wheel bearings or not, You can usually tell a wheel bearing when you are driving the car at highway speeds and you go around a corner and it get quite a bit louder Depending on what way you are turning if your turning right and it gets louder it will usually be the right side front or rear. the left usually the left front or back. some cases I have even heard Axles making a Howling Noise. Please let me know what you come up with. And Thanks in advance If I helped you out any. Bear001
