Re: 03 LeSabre: Rack & Pinion replacement

Fairly easy.......

Steering wheel centered and locked.....

Jack up car....

Remove both front wheels.......

Pop off the outer tie rods from the knuckles.........

Remove the intermediate shaft bolt and separate the intermediate shaft from the spool valve stub of rack.....note the direction of the indentation in the stub shaft....

You are going to lower the REAR of the subframe about 1", for clearance room room....so the bolts will be loosened not removed.....you can put blocks under the rear of the subframe, about 1" below for safety....

Remove heat shield from sub frame......

Remove the plastic clamp that holds the PS lines to the rack.....

Now the hard part.......you will need an 18mm crows foot and long extension ratchet, to break the PS lines from the rack........

Now remove the bolts from the rack......I usually pull it out the driver's side....

Since you centered the steering wheel, the rack is centered, provided you didn't pull on the tie rod end.....

place your new rack next the old rack....make sure the new rack is centered with the stub shaft indentation the same.......now take a measurement end to end of the old rack with the tie rod ends on....take another measurement of the driver's side tie rod end to the side of the spool valve......when you transfer the tie rod ends, you want to get the same measurements........

Just loosening and counting the turns until the tie rod end comes off does not work, because someone during the life of the car may have replaced an inner tie rod that wasn't the "exact" same length, or the new inner rods on the new rack may be slightly different......so measure first.....

You just have to be close, because you WILL NEED AN ALIGNMENT......when you reinstall the rack, even if your measurements were exact, there is play, left and right for the rack which will affect your steering wheel center......so just get it close.....the rack will only change toe in/out.....but toe is the biggest destroyer of tires....so get an alignment....
