Wierd shake/vibration/clunking?!

[blck325is]

Hey guys, my car has been having some shuddering/shaking pretty strong at around 60mph. The steering wheel stays pretty straight but it moves side to side once the car starts shaking.
I have a good guibo, my csb just got replaced, and my tires were recently balanced. My question is whether the transmission might be the problem now because I can't think of anything else.

Half shafts, driveline, steering rack or other front suspension parts?

A vibration that you feel in the steering wheels is from the front suspension. If you feel it only in the seat it is from the rear suspension or drivetrain. Take the car to a shop and have a pro diagnose it.

tire balance or alignment as well.

Bad u-joints have been plaguing me.

a vibration at a certain speed and above is most likely wheels unbalanced or wheel bearings.

Driveline would be at a certain rpm.

Drivetrain is speed specific vibration. Mine was from 65 to 70. Your driveshaft rotates with your wheels no matter what engine RPM says.

i had the same thing 60 mph like clock work. it was my control arm. i suggest you change both sides. i didnt and now like clock work 80 mph shakes my dash.

Driveshaft was recently replaced.. Gonna get under the car and do some poking around.
