hyd. steering help

[BillPutney]

okay guys I have just finished trying to get the shaft out of the tilt tube.I've gotten everything off both ends of the shaft soaked it and heated it .I put the lock nuts on both ends and hammered away with a 4# hammer that we use on the tractor occasionally , Nothing moves , only crushing the lok nut ends.Local Suzuki dealer says I need to replace the tilt tube , but obviously the shaft has to come out first.$64.00 for the tilt tube and none on the East coast,he located some in CA.$ 80.00/hr. for them to try and remove it and no idea as to how successfull the attempt might be.Any suggestions other than biting the bullet and saying FIX IT!!
