Honda V6 with the 5 speed trans
Car has been trouble free.
In the last 6 months given some front bearing issues I replaced both front bearings and both CVJ axles.
Just prior to the replacement I notice a vibration when decelerating.
This is most prominent when driving the interstate at 70 MPH with the cruise control on.
Level terrain all is fine. When going down hill (less engine power required) is when the vibration starts. It is significant and at a rate that equals the tire RMP.
If I an driving w/o CC I essential get the same symptoms but not quite as sever. I can "induce" the symptoms if I give the car a tiny bit of throttle when going down hill.
I'd appreciate any help with this.
Thank you.

What happens if you shift it into neutral going downhill? Decoupling the tranny from the engine and at least initially keeping the RPMs the same?

Obviously do not try this on a crowded highway at 70 mph. Maybe late at night with no one else around.

While in neutral you could also press the gas to get the RPMs up to what they were while in gear and see if that makes a difference.

All with cruise control off....

 

I suspect a motor mount is settled some and that particular scenario is the first shake you have noticed.

 

Andy's experience far outweighs mine.
Follow his guidance.

 

Andy, Derf,
Thank you.
I will check both out.
What does a settled motor mount look like? I am thinking the cushioning material will be compacted toward the bottom of the mount?

Sometimes you have to take a step back to notice one end is lower than the other. Some of our mounts have oil in them and appear to leak.

 

I stood at the front of the car and put a pry bar under the intake manifold and levered it up. I did not see any particular movement or hear any clunking noises.
Is there a better way to evaluate the engine mounts? And, as best as I can tell there are three. One on the driver's side, one at the front of the engine and one are the lower rear. Did I miss one?
Thank you.
Eric

 

Replaced the right side motor mount and the one at the bottom of the engine just behind the radiator.
Most of the vibration issue is gone.

QUESTION:
Are there other mounts for either the engine or transmission?

The right mount was shot and the lower one seemed mushy. (a technical term)
:-)

Rock auto shows 4, my L has one at each end and the engine/transmission hangs from the inner fenders. Then there are two that take the torque front to rear. You can look at pictures and compare to what is on your car.

 

OK.
Thank you.
I'll try them again.
