Noise coming from rear hub after replacing various fluids

I just replaced the engine oil, differential fluid and rear VTM fluid on my 2003 Pilot. Now all of a sudden it is making strange sounds -- coming from rear hub I think. Does anyone know why it is doing this. Never made this noise before. Sounds like a high to mid-pitched humming/grinding sound.

Once you add fluid to the rear differential, you should drive a short distance in forward and reverse. Then take out the fill bolt and add VTM-4 fluid to fill it again. It will take more fluid since driving it a short distance helps the fluid move into the rear end. The noise is probably due to not enough fluid. The fill procedure is fill it once, drive it, fill it again.

Not a solution but check to see if the limited slip differential is at issue. Honda extended the warranty on some models back in the day (in my case up to 108K miles), but I still battle this annoying, dreaded grinding noise on my 2004 Civic hybrid (now at 169K miles).

Maintenance Minder 6 Scheduled Maintenance
Recommended service for your 2006 Honda Ridgeline:

Replace VTM-4 rear differential fluid: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher level of mechanical (shear) stress to fluid or frequently fully loaded. This requires differential fluid changes more frequently than recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions, have the differential fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

The check engine lights and vtm-4 lights of my 2003 honda pilot alway stays on after i went for an automatic car wash. and after a day or two mostly if i ran it on the higheay check engine and vtm-4 light...


Apparently what has most likely happened is you were on a wet or ice road and may have lost traction on the road. You may have never even noticed, but your vehicle did. The vehicle compensated for the road condition & probably revved the engine a little to low, which probably turned on the check engine light. This is a scenario only.

The best way to find out what's wrong is to have the computer scanned for trouble codes. The trouble code will point to the problem. Several auto parts stores will do this for free or rent you a scanner so you can scan it yourself. If the code isn't obvious or you need more help you can come back here and I'll walk you through figuring it out.

It also could be you need to change the rear differential fluid. There was a TSB for this vehicle. I am not sure if your vehicle falls into it. You could check with the dealer as well.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day

When do you change the fluid in the rear differencial. I was told by a mechanic that the rear differencial fluid was low and had metal shavings in it, and that the fluid needed to be changed and that it...


I'd say yes. The differential fluid is often overlooked by oil change technicians, even though it's something that should be topped off periodically.

It probably would cost more than that to repair it once it wears out.

I think that changing the fluid would take about an hour, and depending on the garage, and the labor rate, that they might elect to take the rear cover off of the differential, and drain it that way and replace the fluid once it was put back on. He could inspect the gears while the cover was off and tell you how bad it was.'

Do you hear any clunking or gear mesh noises from the rear when putting it in gear or running the vehicle?


Some mechanics would simply top off the fluid and wait until it wears out, which could be several thousand miles in the future.

Use gear oil for it of the recommended viscosity in the service manual.

Generally thicker than motor oil.

So, adding fluid would cost only the amount of the fluid plus some labor.
A bottle of fluid might cost $9.99 or so depending on where you get it.

You might be able to do this yourself if you crawl under there, remove the fill plug at the top, and just add gear oil. If there isn't enough room you might drive it up on some ramps and then crawl under there.

My 2007 Honda Crv is growling when backing up Honda replaced the rear differential oil at 8000miles and once again at 15k the problem has returned. Has Honda come up with a better solution than replacing...


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.

Whenever I turning into a parking spot my car


This is caused by deterioration of the Fluid in the rear differential of the car. This occurs when the rear end is opened at its extremes at first and will progressively get worse to the point where it will make the noise all the time while driving. First the fluid in the rear end needs to be changed, and replaced with the appropriate Honda fluid (either vtm 4 fluid or dual pump fluid depending on model) if the doesnt immediatley fix the problem, there is a burnish procedure that your local honda dealer can perform for you which involves changing the fluid and cleaning the clutches inside the rear diff. Good luck!

VTM rear differential Liquid needed at how many miles


The diff fluid is only changed if the diff needs repair, or if you suspect water has entered it, check it on a regular basis for leaks and if you think water has gotten in through the vent.
