BMW E34 5-Series 525i or 535i Front Cross-Bar

If you’re planning on dropping the engine and transmission, you’ll need to remove a big, sturdy cross bar that is rearward of the sub-frame. On each side of the car, the cross bar base is attached with a vertical long 18 mm bolt, and two 15 mm bolts.

Coaxing these loose can be very difficult, and I needed to resort to using penetrating oil and tapping the bolt heads with a hammer. Even then, in about half the cases, I still haven’t been able to loosen the large bolts, so I’m planning to use a large breaker bar.
