Burnishing Clutches in Rear Differential
 

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

We changed the oil and 'burnished' the clutches which consisted of:
Putting crv on Jack Stands so all 4 wheels are off the ground, start
engine and let idle until radiator fan cycles on and off two times,
turn off VSA, apply parking brake, shift into reverse, let engine
idle for 5 minutes, shift into drive, remove parking brake, run 5
minutes at 10 mph. Repeat the sequence and then shift into park and
turn engine off. Let cool for 10 minutes, then drain and refill
differential a second time. Each fill takes 1.3 quarts (about 42
ounces) so you will need 3 quarts to change two times. While we were
doing all this, my son-in-law kept saying 'I don't see how changing
the fluid can fix it' but it did. We took the car out and it seems
to be completely ok. The only 'downside' was the fluid was $12.00+
per quart however that was much less than a differential
replacement!

Honda did mine NC @ 30,000 miles but didn't offer
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 had
problems @ 30,000 miles? Although the daughter has' driven the
wheels off hers' much of her driving is trips of 40 miles or so and
hers didn't give problems until about 70,000 or so. Go figure? I'll
take your word on the 60,000 mile change, I must have missed it.
Thanks again

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/60,000
miles. It also says that the rear differential and all interior
parts are a part of the Powertrain? From that I think we can let
Honda do ours again if we have a problem before 60,000 miles. It
really wasn't that bad of a job if you have to do it yourself. I just
hate to pay $12.00+/quart for the fluid and from what I can find there
is no 'generic' equivalent.
