All around suspension issues?

At least i believe it's suspension related. within the past few months, after replacing my shocks and struts with new oem sport suspension components, i had my car aligned at bmw. since then, my rear tires are feathering pretty badly, and i get a moderate amount of intermittent shaking in the front end as well. now i suspect the RTABS are probably worn enough to where the alignment may NOT have helped the situation out, but bmw didn't mention anything was wrong when they handed me back the keys. i have all four of those ready to go, but in regards to the front: ive got new end links, struts, perches (and pads), upper bearing plates, bump stops and sleeves installed... FCABS are in great shape and were replaced just before i bought the car just over a year ago. now for the tie-rods... bmw sells just the outer portion. is that what typically wears out and comes loose? or should i be purchasing the entire assembly? is there anything else i should consider replacing while im down there?any advice would be great as i would rather not replace anymore tires due to stupid wear issues... thanks!

by the by... ive got an 01 330 with sport package, with 177k miles... and yes mango, ive replaced the whole cooling system

You should purchase the entire tie rod assembly. The peace of mind is worth it's entirety and pretty affordable from Lemforder.

Just did my tie rods, just make sure you get a tie rod puller, so much easier than the pickle fork.

As far as difficulty 4/10. Its only that high because the drive to the alignment shop was scary lol

Lol, sounds like it might be. at 177k, is it likely the front control arms/ball joints are shot? i'm trying to locate the light 'knock' that i still get going over a driveway curb. with brand new shocks/struts and endlinks, it's got to be something else close by. and wow, i just took a closer look at the feathering on my rear tires today... close to 3/16-1/4" of difference from one tread block to the next on the inside of BOTH tires. they're done for with tons of tread life too.
