This
is a top level job and must be done with great care! If you do not
feel comfortable or are not 100% sure of your skills I would highly
recommend not attempting this job. Sometimes it is just better and more
cost effective to pay a professional than to make a mess and have to
pay one double!
Start by disconnecting the battery.
Remove the steering column covers with a 20mm torx driver.
Remove the ignition switch,wiper switch and turn signal switches all
are 25mm torx.
Now remove the air bag module. You will need a long 30mm torx driver as
shown below.
Unplug
the module and lay it outside the vehicle with the back(metal part)
laying flat on the ground.
Now
remove the 18mm bolt securing the steering wheel. After the bolt is
removed I paint mark the wheel to the column splines for alignment
reference. Before you remove the wheel you must pin the air bag contact
reel (I use a small phillips screwdriver) There is a small dimple
behind the contact reel hole for proper alignment. If you accidentally
release the contact reel the yellow tag attached to the wire gives
specific instructions on how to re-align it. But we want to avoid this.
With the contact reel pinned you may now slide your steering wheel off.
The below picture pretty much shows all that is described here.
Now
remove the torx screws securing the contact reel unplug and remove
that as well. Keeping the pinning device(screwdriver intact)
There
are numerous
ways to seperate the 2 pieces of the lock cylinder, I prefer to drill
them out and this is the method that I'm going to show. The below
picture(a bit blurry) shows a pen(on the left) pointing to the one
shear bolt that must be drilled out. You must then go to the other side
and drill that one out as well. It makes no diffrence which side you
start with they just both have to be removed. I put a small amount of
grease on the 3/8" drill bit to try and hold the metal shavings. I
would recommend covering the dash and the floor as well to retain the
metal shavings.
The
picture below shows the LH shear bolt drilled through and the 2 pieces
are seperated. Now I'm drilling the RH one.
Finish
drilling through and remove the 2 pieces as shown. Notice the RH
one is not completly drilled through but enough to bend it upward to
clear the column.
With
the old one out of the way wipe off any residual metal debris and
install your new lock cylinder. The 2 bolts supplied are shear bolts as
well(meaning the tops are meant to snap off when they are tightened) so
care must be taken not to cross thread these. Position your lock
cylinder and install your new shear bolts. I make both sides lightly
snug then I go back and tighten them until the top of the shear bolt
snaps off. The shear bolts are 40mm torx.
The below picture shows the new lock cylinder in place and now you are
ready to reverse procedure and reassemble.
