try this for a start

BMW TIS - 31 35 000 Removing and installing/replacing front stabilizer (M62)

there is a write up or post on a thread somewhere with more detail .

X5Girl has a write up on replacing sway bar bushes which will help . says to lower a subframe mount , not too sure myself . the TIS seems to suggest moving left spring strut slightly to make space , I would try that .

try this for transmission connector

instructions are not clear on front shaft . only show rear shaft
BMW TIS - 27 10 010 Removing and installing transfer case (automatic transmission)

this shows the transmission removal . there is more to it if you click back to the TIS home page , find your X5 and see all instructions .
