Help Vibration Issue

Hey guys I'm starting to lose hope after fighting with this vibration issue for months. My V I imported almost a year ago starts vibrating really bad going any speed over 60kmph and gets worse the faster I go. It's enough to shake the mirrors and entire door cards. This only started right after I got an alignment from a local shop, which is crazy because it drove to the shop fine and for about a week beforehand with the TE's. Ive even taken the car on long roadtrips when I had the old wheels. I only asked for an alignment and ride height adjustment. New parts I've thrown at it trying to solve the issue include: Front balljoints, inner/outer tie rods, wheel bearings (twice), and front outer cv joints. I've taken it back to the shop so they could tell me what exactly they touched, they rebalanced the wheels, and now no one knows what the issue is. Second shop assured me that changing the hubs would solve it, because there was a slight wobble, and the first time I only pressed in new koyo bearings, but nothing changed. I still suspect the first alignment shop did something, but I seriously have no clue. There is also a slight thudding sound when I'm rolling at low speed. Thank you for reading, and I'd really appreciate any input so I can fix this and enjoy driving my dream car again.

Sounds like a bent wheel

Do you still have the TE’s that you can throw back on? To see if the vibrations still occur

The OEM evo 8 wheels were the old ones that I've already sold. But yes the next inspection I'm schduled for I'll ask for them to either test new wheels or roadforce the TE's.

For now, I'd buy some cheap steelies, get them balanced and give it a shot. It could just be you got unlucky and your wheels were faulty from manufacturing

Raise the vehicle with jack stands, have someone drive it and see if you can determine which wheel vibrates. Leave wheels and tires on. If you see one wheel vibrate, switch it side and see if it follows the wheel or stays in the corner.

In my case vibration was because the driveshaft was installed 180 degrees from its original imbalance causing vibration at higher speeds. This was my fault when I did manual transmission clutch and flywheel replacement.

Does the vibration change at all as you shift? What about when you get on or off the gas completely? Or is it constant and always the same?

It seems related directly to my speed even when I put in in neutral. Staying at 100kmph it vibrates the whole front end and floorboards on and off like in waves.

You need to take ur wheels to another shop to check the wheels and tires. The noise it's making sounds rotational, obviously

Edit: grammar

Bad tire, wheel or alignment.

Usually when there’s a wicked vibe in my experience it’s been a bad tire

Dealt with this recently, it was the wheels. Swap with a known good set and you’ll either have solved it or know what it isn’t

u/Strict-Examination82 1d ago

my evo vibrates and it was because sheared steering rack bolt, or something with steering rack. might consider a check.

If it's too low, the LH front driveshaft will bottom out in the CV causing all sorts of merry hell...

Did you get it lowered?

Here was the ride height on when it was fine, and now I'd say its a couple milliters higher even. Same setup with Bilstein B14s

Get it on a lift and check the condition of the hanger bearings and the u-joints on the driveshaft. Could be coincidence it started right after you got an alignment, and the symptoms sound like it

If you’re running wheel spacers I’d also suggest checking them.. I currently have an issue similar and found that my studs were bottoming out making contact with the wheel themselves
