I listen to the guys in our shop and I change mine every 30K and have had no problems like the majority of people. Big difference between changing engine oil and diff fluid! |

Replying to: yarmie (Jun 15, 2009 11:16 am) Maybe this is all overblown, but on principal, I'm angry about it. I don't like being deceived, lied to and treated like I'm stupid! Honda corporate does not really have too much control what goes on at the dealership level, unless customer brings it to their attention. The TSB clearaly states that differential fluid changes prior to the scheduled ones are covered by the warranty, and are eligible for out of warranty consideration. Problem is greedy dealers. Dealers are individually owned and operated. And I would not be surpized that some are billing Honda for fluid changes as well as the customer. As to the $17.99 oil changes... It costs me about $5 to do an oil change with Group III synthetic oils (Mobil1, Pennzoil Platinum, Quaker Horsepower, Valvoline, Castrol Syntec), and Honda flter. While the 2 bottles of differential fluid and 2 crush washers are about $9. I usually buy 4 bottles for 4 changes. The best is to do it once a year, along with tranny fluid change, and brake cleaning. It takes me a good chunk of saturday morning to do oil and filter, air filter, cabin filters, differential, tranny, rotate tires, and clean and lubricate brakes moving parts, but then it is done for the year. 05 should have had its brake and power steering fluids changed last year, as well. |

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................

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

Replying to: tedtcb (Jun 24, 2009 10:18 am) And I change my oil every 7,500 miles too. Just like my manual says to do. Any more frequent is just a waste of good oil imo. I guess it's fine if you are one of those oil change hobbyists but that's not me. Why wouldn't you want to follow the service recommendations as published by Honda. Don't you trust their engineers? |
