Yes it did and yes I should have. However, I was late for a meeting and did the cell call routine instead. A couple of days passed before I could actually get the car back to their shop and have them verify my complaint.
Last summer, probably less than 3k miles ago, I did a wet/dry compression test as part of my annual service. I don’t have my service notes in front of me, but as I recall, all 4 cylinders were within 2-3 lbs of each other wet or dry. I don’t have a leak down tester so that may be a good test to have done. Like I said, sitting at idle, the engine is nice and quiet with no rocking around no thrown codes. And, when I really stand it, power delivery is more than ample and smooth.
I’m beginning to think I have two unrelated problems. One, the trans shop somehow damaged the axles thus causing the rotational vibration which varies with road speed. And, two, the transmission may be the source of the vibration I’m feeling through the accelerator and floor board when stopped at a stop light. Be that as it may, the car goes back to the trans shop next Tuesday. Today, I took the shop owner for a ride and he agrees “there is something not right”. Well, duh. Interestingly, the service writer told me 3 different people took it for a test drive, including the owner, prior to delivery back to me. Life goes on, we’ll see what Tuesday brings……
OK. So the tires have been rotated and checked for out-of-round. This is the third time I’ve been through this excercise and feel confident it’s not a tire or wheel issure. However, the rotatoinal vibration remains firmly planted somewhere in the front end. Interestingly, I was under the hood, with the engine at idle looking for “anything” the trans shop may have not gotten hooked back up or tightened down correctly. I layed my hand on the valve cover and the engine is so vibration free I could hardly tell it was running. However the intake manifold is a different story. It’s vibrating like crazy at idle. I checked all the intake fasteners and they are all tight, all hoses are connected. In my simple mind, if one part of the engine is vibrating, shouldn’t any other part of engine?
Another test drive and I noticed the vibration can be felt through the accelerator and floorboard as bad as or worse than through the steering wheel.
So what’s been done to this car in the last 6 months:
New Honda pads all the way around (Great video, Eric)
Flushed brake fluid
A couple of oil & filter changes
One trans drain and fill (pre surgury transmission)
Tires rotated, balanced and checked for out of round 3 times
RF wheel bearing replaced (Dealer ripoff trying to diagnose the original carrier bearing failure)
Transmission swap
Front end goes to hellThe car has only 53K miles on it, so it’s not exactly a high mileage grinder. Tires are 1 year old Goodyear Assurance Triple Tread with less than 6K miles on them. Exept for the transmission, everything else is stock OEM.
The vibration is at all road speeds and seems to increase in severity with speed. I had the front wheels checked for balance and they were ok.
I fully intend to return it to the shop. The problem being it’s a 100 mile (my bad) round trip and a pita. Unfortunately, there are no local shops beyond the so-called Honda dealer around here, so, I’m trying to gather ideas for the possible cause(s) of this kind of vibration before I make the trip. All input is appreciated!
Turned out to be a failed differential carrier bearing. Trans was replaced with H&A reman out of California.
