I have a '94 Accord EX with a F22B1 auto for a beater. The vibration just started last night on my way home from work. Then I notice how bad it shook while driving to work today. The vibration starts from 60+mph and won't go away. The front driverside bearing is going bad but it hums at a low tone, but no play on the hub at all. Also, my dad said he replaced the axles already, so I'm still not sure if they're bad or not. Going to inspect them.

This is what I replaced like a week and a half ago:

-Four new snow tires; mount and balanced by me.
-Did a alignment by me
-Replaced driverside lower balljoint + both outter tie-rods + both UCA by me

It didn't do this after I replaced these parts like almost two weeks ago. Just started last night. Can the balance shafts cause this vibration at a certain mph??? It still vibrates from 60+ even if I'm in Neutral with no loads to the engine.

Any ideas??? I read one thread that it was his lower ball joint that caused the vibration and went away after he replaced them.

 

Reason I said balanced shafts is because on my other Accord with the H22A, I timed the balance shafts and there was no more vibration from 60-70mph anymore because before that, it would vibrate like hell in that mph area.

Either it's a bad motor mount, balance shafts needs to be timed, wheel bearings bad, or bad axle on my DD in the first post above.

 

Did you dynamically balance the tires or is it bubble balanced statically? Laser aligned, sounds like you have access to a shop and expensive equipment? Snow tires are usually super soft rubber and not the best quality in my experience...you might spin it again and make sure you didn't split a belt or something weird. Loose lugnuts...I dunno.

Given the timing I'd suspect tires first. It sounds like you're intelligent and its not just a warped rotor that occurs only when braking...

 

balance front tires chek tie rods

 

Thanks guys.

I decided to balance the two front wheels anyway just to see, and they were off half an ounce to an ounce. I also balanced the rears too and they were half an ounce off. On my way home, it doesn't shake like it would anymore. Weird as hell that it didn't do this to me when I threw my snow tires on. There's no play in the front suspension whatsoever and both axles are in good shape with no tear in the boots. Still has a little bit of shake to it, but not as major as it was on my way to work today.

Thanks for the comment. I dynamically balanced the tires as we have a decent wheel balancer at our VW shop. And also, reason I didn't say it was a warped rotor is, because it shakes when I'm gear and in Neutral not depressing on the brake pedal at all. So rotors are out of the question. And yes, I agree with you about snow tires aren't the best when they're soft, but here in MN, it's already 40 and under, and manufacturer don't recommend you to drive on snow tires when it's 45 degrees or over which is why it's ok for me to be on snow tires as it's snowing out as of now. Lol. I use a torque stick while torquing down all my lug nuts. And everything up front is solid with no looseness from axle to any ball joint you see. But yes, it was off when I threw those wheels on the balancer machine.
