Honda CR-V Rear Differential Problem?

Replying to: njlou1960 (Jun 23, 2009 5:36 pm)

Well, add another to the list. I encountered the same "grinding" noise, a friend said it could be the differential. I did my net search, found this forum as well as others before taking in my CRV to the dealership. When I took it into the dealership, they told me they would look at it and let me know. They called me 2 hours later and told me the differential fluid needed to be changed (32k), would do it for free. That is when I told them I was aware of TSB07-21 and and TSB07-24. During my conversation, the :"shift" was always towards consumer blame on behalf of the dealership and claimed that the manual does state changes every 15-20K(not). They agreed to do the fluid change and burnishing free of charge this time, but told me there would be a charge in the future, as if they expect it to happen again. My main concern is what happens if the differential locks up? I have the Honda Care extended warranty, but it states that "mechanical breakdowns due to contaminated fluids are not covered". The way Tsb07-24 is worded is "noise from contaminated fluid" appears to indicate a loophole for convering differential replacement resulting from their problem. Should I contact Honda Corporate? Concerned my $$$ was wasted on the extended warranty for defective craftsmanship................
 
How is changing differential fluid a defective craftsmanship? Sounds like part of regular maintenance regimen.
 
However, since we are all experts on what defective craftsmanship and what is not, on these boards...
 
Please tell us, in your expert opinion, what do you expect the dual pump fluid to last (distance and time) in this particular application?
 
Also, what chemical modifications would you, as an expert, perform to prolong the life of the dual pump differential fluid?
 
Perhaps provide a sample chemical formulation for the new and improved dual pump fluid that satisfies the regimen outlined in the first suggestion.
 
Feel free to use organic and inorganic friction and viscosity modifiers, and bear in mind the cost limitation of the per quart value that average consumer is willing to pay.
 
Thank you. Looking forward to expert's advice.

For my first 15- 20 years as a Honda owner, I changed the oil myself.
For the least 10-15 my mechanic does a “service” every 3K. We drive 240 miles a weekend up north and back and the way I figure it, yes, it’s overkill, but no one ever robbed life from a vehicle by changing the oil too much.
 
Did I forget to mention that I also change my transmission fluid with every fill up?

Weren't you the guy who said you could change your transmission fluid in 30 seconds flat?
