Loose Steering + Steering Vibration at 45-50 MPH
I've got a 2000 E55 Wagon, approx. 101k kms.
I've done a bunch of reading, and this post was super helpful:

I've got both A) the vibration at 40-45 MPH, when the car is cold it's most pronounced, and b) I've got really loose / tramline steering (noticeable above 30-40MPH).
I'm not sure if these are related, or I'm just lucky and have 2 separate issues at the same time.
I'm going to get the rear subframe mounts replaced (haven't checked yet but guessing its worth a shot), and new rear tires. Is there anything else that I should get done at the same time, in case the vibration isn't this issue (and to save on labour and future headaches)? I've seen that it could also be a rear propeller shaft/driveshaft issue as well, so I'll look at that too.
I've already replaced:
- Front upper and lower control arms
- Front ball joints
- Front tie rods
- Front dampers (bilsteins)
- Front sway bars and links and bushes
- New front tires
- Engine and transmission mounts seem to be okay and replaced before I got it

Doing some research, the 4 subframe mounts/bushes for e55s have these part numbers:
2103507408
2103507508
But it looks like the second part is discontinued: https://www.fcpeuro.com/products/mer...507508#fitment
Anyone found them recently, or know the difference between these and the regular w210 parts?

I think E55 rear bushings have more solid rubber, to take that extra torque compared to rest of the W210s. I actually recently ordered new bushings for my rear subframe and my delar said 2103507508 (which was a kit for both sides) is now replaced with:2x A 210 351 12 42 – bushings around 90 USD/piece
2x N 009021 013203 – washers 2 USD/piece
2x A 202 990 05 04 – bolts 7 USD/piece



I've got the rear mounts to do, and will see if that helps.
I'm also looking into the servotronic to see if that's the issue with the light steering.
