Right forum, wrong area, TDI 101 would be better place. This is for power enhancements.
But to answer your question, it could be suspension related. We need more information. Does it vibrate the car or just the steering wheel, does it change on braking, decelerating, accelerating, do you feel it though the brake pedal, does it change going around corners left or right, can you feel it in the shifter, when was your wheels ballanced last, how much treed is on the tires, age of the tires, put the car in reverse and lock the wheel all the way to the left and back up and try again to the right do you hear a clicking sound, are your CV boots intact, are all the bolts holing the axles tight, did you hit any big pot holes lately etc...
Could be a bad strut or shock, busted bushing on the control arm, wheel unbalanced, CV axle etc. we need more information
Highly doughty it’s the transmission, might be the mounts though, who knows. We can walk you through some testing you can do to narrow the results down to a few things.
I’m leaning to a bad suspension component or axle joint or unbalanced tire.
