The balancing lines where still leaking after the O-ring replacement. Spend 1.5 day swapping the hard lines. The sub frame had to be lowered approximately 5 -8 inch, steering rack can stay in place to replace these hard lines. Front suspension too, I only disconnect the steering arm from the knuckle.
No luck still leaking. Looks like the o-rings are not being compressed enough. Tried putting a washer behind the collar of the hardline but still leaking.
Has anyone else experienced this?

I just replaced my steering rack with a used unit. Its actually not a bad job. One thing suprised me was one connection was finger tight but not leaking (assume low pressure) i re-used the o rings and they dont appear to be leaking. Only thing i regret doing is allowing the oil to seep/drip into the sub-frame causing it to appear like a leak after fitting the replacement rack. Anyway got it all cleaned up now and just need to drive it too check any leaks/ive ordered new o rings in case.
