rack will help you out. I remember when I was installing my rack, I couldn't figure out why the knuckle wouldn't reach the rack. I ended up using a clamp to pull it towards the rack so I can get the knuckle in place. Unfortunately, because the rack being angled wrong, I was getting that lump when I would turn the steering wheel.
I think you need to loosen up the steering rack brackets a bit and angle the rack correctly so the knuckle can just slide in easily. At least that's what I ended up doing and it solved my lump steering.
