2005 Odyssey - shimmy at 60+

[Bob Kontak]

Found a fairly bent wheel in right front. I could feel it shake through the steering wheel. I just bought a complete set of new wheels and tires.

There is now a shimmy (vs shake) starting at roughly the same speed. Deal is no sensation through steering wheel. No pulsing through brakes, either.

Shimmy stops when the least bit of acceleration or deceleration takes place. It's only when cruising. If I micro feather the throttle on an off I can find a spot where some kind of harmonic is established and it almost reaches shaking.

Motor mounts are tired. Engine moves more than it should when shifted to drive or reverse from neutral. If load is put on engine with brakes on engine lifts up. Not as much as I have seen on other cars but more than it should.

Only thing left is drive shafts and I would think I'd feel that through the steering.

Thoughts?

I've got a CV going out. Usual clicking during turning. It's now starting to lightly shake/shimmy at freeway speeds.

If the right front took a hard hit, I'd also look for slop in bearing. I had this in the rear of my 951. Never made noise, just slop. My wife also hit a deer with her right front wheel once. That bearing went south some time later.

Had this happen on two different cars. One hit a pothole hard, the other slammed into a curb. In both cases, the wheel bearing was the culprit.

Bearing, maybe strut or tie rod end.

It will almost for sure be an axle shaft issue, . I did 2 of these in the last season, both times, it was the inner joint of the axle shaft that had the most play . Check the longer side first, the one with the carrier bearing on it . I also had one , where that carrier bearing ist kaput, and had significant play , same symptoms as yours .

I'd be tempted to start with a Hunter Road Force balance on all four wheels, but only because I have had so much luck with doing so.

No suggestions other than go through all the front end components (tie rod is my bet), but let me say that those Gen3 (RL3/4) Odysseys are the bomb.

Hub bearing(s) check first. Check strut springs and mounts as well. Damn, they are steep for decent loaded ones. Even Rock Auto is over $300 for KYB

I do feel if the carrier bearing/inner CV is sloppy, tired motor mounts would allow the engine to get into the shimmy mix.

I cannot isolate it to any corner on the car. Kinda feels more in the middle but not distinct as nothing it transmitted to my hands or brake foot.

I was thinking of Gorilla taping my IPhone with the flashlight on and take a video of the engine while cruising.

Thanks for the input. It's probably what FF says which is fairly inexpensive. Just some grunt work/time and I have a press for the carrier bearing if bad.

Now road balancing is not a bad idea but I am thinking at 200k miles first generation parts are going south.

I'll check but three or four months ago did ball joints and at least one tie rod, one hub bearing and rotors. But I ain't getting cocky.

It really is a work horse.

lol- Sounds like my car a while back. I redid the same things, and a new ball joint crapped out. Not in 3-4 months though. It took longer, but I wasn't able to spot it when the wheel was off. The springs had it at such an angle it felt good, but wasn't.

Funny thing was, since I had replaced all the joints, I figured it HAD to be the motor mounts. Changed those, no luck. sob! Not saying that's what's going on in your situation.

Clunked like a motha' though, so I knew something was wrong.

I think I even mounted a go-pro in the engine compartment/ and under to try to spot the engine moving. You should give that a try, and use a sh#$load of ducktape. I think I even honked the horn when the problem was occurring so I could time it on playback. Neighbors thought I was crazy. I couldn't see anything, but I felt very 'scientific' when I did it. Id go with FF though

Had a similar mysterious steering wheel shimmy in an '06 Acura MDX when the car had about 140K miles on it. Shimmy would be there at various speeds some days, not on others. Turned out to be the power steering fluid. The fluid level was ok, but changing the fluid using the approved Honda power steering fluid fixed the problem. Went through new tires, multiple balances, alignments, etc. before the fluid replacement. Thinking at some point when the car was serviced, the incorrect power steering fluid was added.

Must have been some sort of viscosity issue when warmed up. That one's way out there but you just never know.
