Thanks deadmn1337, I ended up replacing the LCA rubber mount on both sides.
I also replaced items 1 to 7 in diagram on both sides.

If you are replacing the lower shock mount, the one in the aluminum control arm,the 2 torx bolts are size e-12 external torx.

I just replaced the struts on my e90. I don't remember the sizes of the sockets I used, but most of the sized described in this DIY and the front strut DIY are wrong. OEM struts from a 2007, the struts dated 3/1/2007 if I remember correctly. Sorry I didn't write down the sizes but I was powering through the install, it was hot in the garage.

To the guy that suggested the pass-thru socket set, THANK YOU. Such a time saver.

I just did this job on my 2006 325i sport package last weekend. This job is very easy, particularly compared to the water pump and thermostat I did last month! Anyway, I used Bilstein B4 p/n 19-135052. These are a perfect fit and a nice stock replacement. The hardest part of the job is actually removing and installing the interior trunk carpet panels. Buy an $8 trim panel fastener removal tool from Amazon! It is not difficult to compress the shocks by hand. For reference, I'm 5'7" 160 and sit in front of a computer all day. I replaced the upper and lower mounts, but this probably was not necessary if you are on a budget. The upper mounts especially looked and felt like new. BMW parts are really well made. All my suspension components are solid and like new after 9 years and 92k and 7 Boston winters. Except the shocks.

Thanks for this DIY. I did this last weekend, with a bad back as well. Took me 2 hrs as I had to watch how much I was bending over.

The process is relatively straight forward. I think I had more of a hard time with the stupid lining in the trunk than the shocks themselves. LOL. I replaced with B4's. Not having a 16mm open end wrench I used a 5/8 which instead which worked fine.

The new B4's had a 15mm nut on the bottom end as opposed to 17mm, weird but it worked out fine.

Thanks to the OP for posting the DIY as it was invaluable. Next up, is the front struts!
