I replaced both front lower control arms with OEM units and new bushings this week. That took care of the dreaded wobble.

did it fix a 60mph vibration or the 20-25 vibration? And were they visibly damaged? Were the bushings shot? I couldn't see anything from what I remember looking at them

UPDATE: So today I installed a new OEM genuine axle on my right (Passenger) side and that has fixed the 20-25mph vibration for the most part. I would say the vibration is about 90% gone. Still a very slight vibration but I guess I can live with it. Possibly intermediate shaft is damaged from the continuous vibration as someone in this thread above said. The 60 mph vibration still persists. Ball joints, tie rods, wheel bearings, motor mounts are all good. Lower control arms look good but I'm not 100% sure. No clue what it could be. If anyone could recommend some stuff that would be great. Will update again if I find anything out.

Do you notice any noise increased around the same time when the vibration started?

I feel like I hear a whirring noise coming from my wheels, but my new tire tread is pretty aggressive (BF Goodrich comp 2 a/s) I can't tell if it's just tread noise or something else. Had my wheel bearings checked today by a mechanic at my work and he said they sounded/ felt fine. He also said he doubted a bad wheel bearing would cause the vibration I have. But I'm not sure. I also took the plastic belly pan off underneath the car just in case that might have been flopping in the wind and causing vibration but it still persists. It's strange because some days the vibration is stronger than others, and it happens while coasting and while accelerating. Shaking is coming through the steering wheel and not the seat.

I saw your post on another thread and you said you had 60mph vibration before. Does the current one feel the same as the old one?

My experience is powertrain or rear hub vubration usually come with noise, so if you do not notice any noise this is going to be a tricky one to judge from internet.

Also, I honestly think for this kind if minor vibration issue, mechanics are usually not good at tracing the root cause. They are too used to more serious issues. So if more than one mechanics clear the suspension, steering and bearing, then I think you either need to look at tires, the other end of the car, or look at powertrain/accessory.

I know you have new tires, but you said the degree of vibration changes sometimes. Do you notice a correlation with ambient temperature? If so, I would say tires are worth looking into. Try changing the tire pressure, and see how the vibration becomes. In my previous experience with tire-related noise/vibration, the vibration felt worse when I lowered tire pressure. The Goodrich tires are known to generate some noise and vibration as they wear.

The powertrain/accessory suggestion also don't match with the fact that vibration persists in coasting. But it will at least make sure the vibration you feel in the steering is clean, and not compounded by multiple of issues. TSX steering wheel communicates tons of info, and I have learned that it can be misleading at times.

My 60mph vibration now is not the same as the one I had a year ago. The old vibration would only vibrate upon acceleration and would go away while I was coasting, that's why I knew it was axles. So when I got new aftermarket axles the 60mph vibration went away then the 20-25mph vibration appeared.

I don't think it has anything to do with tires because it was doing this vibration a couple weeks before I got new tires/wheels, I thought new tires would fix the problem because my old ones were getting pretty bald. I will still try to experiment with tire pressure and see if that does anything. I do live in ohio, so the temperature does change quite a lot. I think that is probably the reason it only does it on some days. Maybe a bushing is bad and when it's cold it is hard and vibrates, and when it's warm it is soft and absorbs vibrations more. I'm not sure.

Any vibration (even slight) as you gently apply the brakes at 60+? Rotors that are out of true can cause a slight steering wheel shimmy.

Does the vibration seem to oscillate/change intensity back and forth while at a steady speed?

New brakes and rotors probably 2 months ago, no shimmying while braking. And I would say the vibration pretty much stays the same the whole time, although maybe I can't tell. Some days it's worse than others though.

I just changed out my axles to the insane shaft both left and right and also changed out the intermediate shaft and new wheel bearings. My 6mt Tsx feels great now no more vibration at all. You might want to try that but it will cost some money

What vibrations were you having? I'm kinda thinking wheel bearings for my 60 mph vibration

You'll know if you need wheel bearings. If they were trashed enough to cause a vibration the noise would have tipped you off way sooner.

Damn man. This is really pissing me off. On top of my 60mph vibration, even after a $500 axle Iím still having a ever so slight vibration from 20-25 I donít know if I should replace the intermediate shaft or the other axle next. Heel toe told me that the intermediate shaft probably wouldnít be the issue but other people have told me their vibration went away after intermediate shaft. I have coilovers and upper control arms on the way but I doubt those would affect my vibration at all

I understand the frustration because I have thrown parts at my car and issue still remains. Maybe you want to invest in a set of chassis ear? Vibration usually comes with noise, thus chassis ear might help you narrow down the source.

I am buying one myself...

I'm replacing my passenger axle this week and I will also be replacing the intermediate shaft bearing. It seems axle vibration could easily cause extra wear on the bearing as some people have reported vibration until it is replaced. The bearing is only $40 + $15 seal and I will never have easier access so I'm just doing it. Hopefully I can get the bearing out and the new one in without having to take it somewhere to be pressed.

Keep us posted on whether or not the intermediate shaft bearing helps
