An 18mm nut and bolt secures the lower control arm to the rear knuckle and must be removed.

Like the strut-to-LCA bolt, this may require "finessing" the lower control arm with a jack to remove.

When reassembling, torque this to around 35ft-lbs. You will need to do some prying with a pry-bar or large screwdriver in concert with a jack to get this realigned so you can re-insert the bolt.

This nut is identical to the one removed in the previous step, but the bolt is shorter. Don't mix them up!

After this step, the lower control arm should move freely.
