Hi everyone,
I have a vibration issue in my '03 Fit. The vibration is silent, as in I don't hear any grinding noises, etc associated with it. It is at its worst when accelerating between 60-70km/h or so. Above and below these speeds it is pretty much not an issue. If I'm paying attention, I may notice the vibration at other speeds, but it is so subtle that if I wasn't looking for it, I would probably not really notice it.

When I jack up both front tires off the ground and try and wiggle the wheels I don't really notice any obvious play in the suspension, but I'm not exactly an expert mechanic. The front shock absorbers do move around at the top mount a bit, but my understanding is this is normal. However, they may move around slightly more than on our other Honda Fit. Nothing seems obviously wrong with them. I've tried swapping around the front left tire (the more worn looking of the front tires) with the front left tire on the other 'good' Honda Fit, and it made no difference.

Any other suggestions on what I could chase? CV joint? How would I check that?
Cheers!

 

Swap both fronts to the rear and see if the vibration changes. If you're feeling it through the steering wheel and the steering wheel vibration goes away when you do this, it's a wheel/tire issue (bent, wheel weight came off, tire issue).

 

Thanks for the reply. I haven't swapped around the wheels yet, but the vibration is coming more from the seat/at my feet than through the steering wheel. The steering wheel doesn't seem to shake much at all, at least compared with when I drove another car with warped front brake rotors.

 

Have you checked the rear tires yet? You should rotate them if you haven’t recently. My fit made weird “whu-whu-whu-whu” noise and vibration at speed that ended being “cupped” rear tires. I guess the torsion beam suspension setup is kind of rough on tires back there so they should be rotated p often. (so I was told).

 

So I tried swapping out both rear wheels with ones off of a "good" Honda Fit, and it made no noticeable difference.
Another piece of information that may help, it seems that if I'm accelerating through that speed range (~60-70km/h) while turning right, the vibration doesn't seem to be there. Going straight or turning left while accelerating in that range, and the vibration is obvious.

 

another update...
I tried driving around in tight circles at slow speeds to see if I noticed or heard anything... I didn't in either direction, so I presume it's not the CV joints??

I lifted the front end of the car on to jack stands (both corners) and tried to look around for play in suspensions or axles. I didn't notice any play in the axle on the shorter side. On the other, longer, side, (right side) there wasn't anything too obvious either. However, there may have been a very slight amount of play when I tried to rotate the axle while holding it near that rubber damper? thing that is toward the center of the axle.
(you can see the "rubber damper" I'm talking about in the photos of the axle here: https://www.velocitystage.com/produc...e-shaft-japan/ )

 

Hey, were you able to resolve this issue? Running into the same type of problem.

 

I can't really remember exactly, but weirdly, I think it ended up smoothing itself out over time?? I don't remember doing anything specific to fix it. My guess is an imbalanced tire or some uneven tire wear or something?
It's either that, or I just lived with it until I sold the car a couple years later. We had 2 Honda Fits back then, and I can't recall which one had the issue.
Sorry I can't be of more help! and good luck
