Changing the power steering rack on a 1994 Jaguar XJS L6

You'll need:
  1. Beck Arnley 108-1049 Remanufactured Power Steering Rack
  2. OTC 6297 Ball Joint Separator

Here is the procedure for changing the power steering rack on a 1994 Jaguar XJS L6.
  • Remove the 'X' Brace. There are 4 bolts, the two bolts in the back are 19mm and the two in the front are 15/16. You should do this on the floor although the pic is with the car in the air to show you where the bolts are.
  •  Remove the key and lock the steering wheel in the foward position.
  • The good thing about this rack is that it can only fit one way with the steering shaft, so remove the bolt and wiggle the thing out. If it is corroded, spray it with Rust-off or some similar product, mine came out easy :D
  • We need to disconnect the tie rod ends. Undo the nut, but not all the way, and with a tie rod separator, I used the OTC 6297 Ball Joint Separator, separate the tie rod. You put it like I did on the pic, hold it with one hand and a rag and start screwing the tool with a 15/16 and a ratchet clockwise until it pops (big pop don't get scared now). Take the tool out after the pop. 

  • There are three bolts holding the rack to the sub frame, all 13mm, on do the and pull the rack, which is still attached by the tie rods and the steering lines if you followed instructions. I do it like this so its easier to get to the lines which are in an annoying position.

  • Before you undo the lines behind the rack, I recommend taking the two holding brackets in front of the sub-frame, two little Phillips, so the lines have some play and they are aeasy to work with.
  • Now to undo the lines which are behind the rack. Fluid will come out so put a bucket or something to catch the steering fluid. There is four lines, we only need to undo two, the ones facing the right side of the vehicle. on the pick you see a wrench about to undo the first (top) line.
  •  After you undo both lines, push them back out of the way, and undo the nuts, which should be loose, and the tie rods cracked with the OTC tool I mentioned before. Don't let the rack drop on you :D. Put the rack on the table. there are 3 shims, and a black bracket that goes on the driver's side of the rack. the shims go toward the inside of the car. 

  • All you have to do now is reverse the procedure to put the new rack back. The pain is in placing the shims back in place. 
  • Hook the tie rods and snug the nuts by hand.
  • Catch the bottom line, tighten it, then the top line, tighten it. Tighten the lines brackets in front of the sub frame.
  • Place the new rack with the black bracket and shims in place, align the holes with a screw driver and put the bolts through. I do the passenger side first and then the driver's side.
  • Tighten the three bolts.
  • Tighten the nuts for the tie rods.
  • place the steering shaft back in place, not how it goes, it can only fit one way, or the bolts won't go through. 
  •  Tighten the bolt and nut.
  • Refill the reservouir, start it up, move the steering wheel side to side and recheck the fluid. 
  • Place the 'X' Bracket back in place.
  • Tighten the four bolts for the 'X' Bracket.
