Question about 1999 Lexus LX470
1999 Lexus LX470 Steering Column Lock Assembly (SCLA): My ignition crank shaft was broken inside the SCLA so I replaced the SCLA. I reattached the electronics to the SCLA and reinstalled the key cylinder with the SCLA ''inerds'' and the key cylinder (with key) set to 'Accessory.' My vehicle now starts with the key but the steering locks when rotating the wheel and then with a little tug will allow another rotation. Did I install the key cylinder incorrectly into the SCLA where it will not allow the locking mechinisum to disengage? Is there a proper way to do this? Is it finiky? Is there a proper orintation for installing the key cylinder? Do you hook up the electronics first or last with regard to the key cylinder? HELP!!!!
I'm in the middle of repairing this right now on my 2000. I noticed that in addition to the two anti-theft bolts that need to be removed, there is another bolt on top of the SCLA that when screwed all the way in, is supposed to align with a hole in a rotating assembly that is inside the steering column. I believe that if this is not aligned, then it won't hold the lock in place and when you turn the steering wheel you might get the behavior that you are seeing.

REMOVAL & INSTALLATION The steering lock/ignition switch/warning buzzer switch assembly is attached to the steering column by special bolts whose heads shear off upon installation. The bolts must be drilled out to remove the assembly or be removed with an appropriate tool. The bolts may also be removed with a hammer and chisel by notching the bolts and tapping them counterclockwise with the hammer and chisel.
The ignition switch or warning switch can be replaced without removing the steering lock assembly. The ignition switch is on the back of the assembly and the warning switch is on the side.
CAUTION The models covered by this guide may be equipped with a Supplemental Restraint System (SRS), which uses an air bag. Whenever working near any of the SRS components, such as the impact sensors, the air bag module, steering column and instrument panel, disable the SRS, as described in Chassis Electrical .
