2008 BMW 328xi shaking problem/steering wheel click

[tbutz12]

Just bought a 2008 BMW 328xi, and after buyingI realized that around certain lower speeds if i go up a hill, the car shakes really bad from the floor board... and also, it shakes at high speeds around 70mph. i took it for an alignment, wheel balance, and tire rotation. Still doing it. checked ball joints, tie rods, top strut mount, axles, stabalizer bars, all are ok. Dont know what the problem is... also, the steering wheel sometimes clicks/snaps when turning it... dont know if its in the column or exterior... i got an oil change already... any advice is appreciated... first time posting... thanks

Would you describe the shake as a shimmy from the vehicles suspension, body,
or more of an engine vibration, misfiring, sputtering?
Perform a diagnostic scan if a scan tool or BMW software is available.

i would say the shaking feels like it is in the center... kind of feels like near the floor... also feel the shaking in the wheel as well. i already performed a scan on it, no codes or anything... almost as if the car is in too high of a gear and too low of rpms... that type of shake. but that is not the case, and it changes gears fine... sometimes a little rough and shaky when down shifting at lower gears... it is an automatic

i do not believe it to be an engine shaking or misfire... although i cant locate exactly where its coming from...

This is the likely suspect:https://www.fcpeuro.com/products/bmw-centre-mount-aluminium-26128615621

I would still inspect motor mounts.

Not sure about the steering wheel click but could be this;

Being an x-drive I would recommend getting the transfer case fluid changed..

UPDATE!!!
so it appears as if my steering wheel is constantly vibrating no matter the speed... also, the transmission shifts down pretty rough and jerky only sometimes... the shaking, feels like it is the entire car.... mostly towards the floor in the center. I am going to change the tranny fluid, the transfer case fluid, and change that driveshaft support bearing you sent me and see what happens after this I suppose.... hoping my transmission isn't crapping the bed...

I would change the transmission and transfer case fluid and add the shudder fluid to transmission

You can inspect the flex disc,drive shaft, and center bearing while your under car..

Changing the fluids is recommended maintenance anyway, but don't add any snake-oil additives.
