Burnishing Clutches in Rear Differential

I have a 2006 CRV with 30,000 miles. Some time ago we began to notic
a 'noise' in the rear end. This noise was heard at low speeds whe
turning sharply. The noise steadily got louder and we took it to th
dealer for diagnosis. They said there was a Service Bulletin ou
requiring a fluid in the rear end be changed every 30,000 miles an
this would take care of our problems. They did so under warranty an
it indeed did fix the noise. I noticed on the Work Order that the
also 'Burnished" the clutches in the rear end. The reason fo
my question is that my daughter also has a 2006 CRV however she ha
80,000 miles on hers and the 'noise' has progressed to a 'click' an
maybe a little jerk when the vehicle is turned sharply. Of cours
hers is out of warranty. Her husband, who is a diesel mechanic
called the dealer and discussed their problem and they said to chang
the fluid, drive it a few miles, and change the fluid again and thi
should take care of their problems. They mentioned nothing abou
'burnishing the clutches'. Am I correct in assuming that driving an
turning forcing the clutches to work will 'burnish' them? Also, sinc
there is no mention of this fluid change in the Warranty Book, do yo
suppose that if further work is needed that they might cover tha
under warranty?

Thanks for any information on this subject

 

I thought TSB's were covered no charge?

 

It depends on what it is and what the manufactorer wants to "do" about
it. TSBs aren't like recalls. They don't even have to tell you about
them. In fact, if it weren't required by law, "they" wouldn't let you
know about them at all.

 

I think driving and turning will eventually burnish the clutches, just
not within 5 minutes the way the TSB does it (jack up the car and run
it with the wheels off the ground). The best solution overall is to
remember at what mileage the noises started and change the fluid
before it gets to that point the next time so you don't have to do any
burnishing.

TSB is a Technical Service Bulletin. They are simply improved or
changed maintenance procedures provided by the manufacturer to the
dealers. They have no warranty implications one way or the other
unless the manufacturer also includes some warranty guidance with the
procedure.

With regard to your daughter's '06, look a little harder at the
service schedule. You will find a reference to changing the dual pump
fluid at 60,000 miles in the "severe" schedule.

address but it is Honda Service Bulletin 07-024 DATED October 3, 200
We changed the oil and 'burnished' the clutches which consisted of:
Putting crv on Jack Stands so all 4 wheels are off the ground, star
engine and let idle until radiator fan cycles on and off two times
turn off VSA, apply parking brake, shift into reverse, let engin
idle for 5 minutes, shift into drive, remove parking brake, run
minutes at 10 mph. Repeat the sequence and then shift into park an
turn engine off. Let cool for 10 minutes, then drain and refil
differential a second time. Each fill takes 1.3 quarts (about 4
ounces) so you will need 3 quarts to change two times. While we wer
doing all this, my son-in-law kept saying 'I don't see how changin
the fluid can fix it' but it did. We took the car out and it seem
to be completely ok. The only 'downside' was the fluid was $12.00
per quart however that was much less than a differentia
replacement

Honda did mine NC @ 30,000 miles but didn't offe
to do anything about my daughter's @ 80,000? Warranty was 60,000

Thanks for the info. Ours would probably be considered 'severe
because most of our driving is short distances, etc and we ha
problems @ 30,000 miles? Although the daughter has' driven th
wheels off hers' much of her driving is trips of 40 miles or so an
hers didn't give problems until about 70,000 or so. Go figure? I'l
take your word on the 60,000 mile change, I must have missed it.
Thanks agai

 

No, warranty was 36,000, severe service schedule is 60,000. My '06
needed it done at 29,000 & the dealer did it without a whimper and
gave me a copy of the TSB as well. I'm thinking I'll just buy some
fluid and change it myself at about 58,000 & see if I can stay ahead
of it.

My book says basically 'Bumper to Bumper' warranty, except for tires
is 3 years/36,000 miles and Powertrain Warranty is 5 years/60,00
miles. It also says that the rear differential and all interio
parts are a part of the Powertrain? From that I think we can le
Honda do ours again if we have a problem before 60,000 miles. I
really wasn't that bad of a job if you have to do it yourself. I jus
hate to pay $12.00+/quart for the fluid and from what I can find ther
is no 'generic' equivalent
