ok 2000 si:

the issue is vibration at throttle, highway speeds and highway speed braking

i checked the front end out, tie rods, ball joints, axles, and bearings. had the wheels rebalanced and then rotated when that didnt work. i did replace the axles because that is the only part i found any play in. which decreased the amount of vibration.

i am thinking:
my new tires are defective. last month i picked up 4 falken 912.
bent rims, lots of potholes here in canada ( bends could be unvisible to naked eye) i do not see any bends tho.

i am pretty stumped on what could be bad.

forgot to mention, since the axles i want to try another 100% balanced wheels from a buddys car. pretty much since the axles i need to re diagnose.

Have your toe adjusted,motor mounts, or your steering rack is loose.

i will go for an alignment asap, and i will check over the mounts/ rack tommorrow.

Vibration during acceleration is often caused by worn CV joint(s).

Even if they feel tight and don't click and pop when you turn the wheel, they
still could be worn.

This.

I Also had vibration upon accleration which was my axles. I went through 2 sets of brand new (aftermarket) axle assemblies before I installed a set which were ok.

i swapped axles both sides, and then the drivers side again. there is no play in the axles/cv anymore.

checked rack/mounts no play.
