OK so as expected our LDV needs the steering box for the test. Bought a replacement, no problem. Getting the old one off, on the other hand, big problem. All the bolts are out. It just won't come off the chassis. My mate had hammered it with a 4lb hammer for hours. He's kinked the chassis hanging off a bar trying to lever it off. He's tried heat, cos the box is fucked anyway so we don't care if it damages the seals.
Is there any trick or advice I can offer him?
