The procedure is the same on every vehicle that uses this type of opening assist. So here is another persons instructions on a GM product.
Tools used:
Leather gloves!!
3/4" combo wrench (biggest I had)
1/2" deep socket (3/8")
6" extension (3/8")

1.With the trunk lid up and the curved part of the torsion bar against the rear trunk wall, I slipped the box end of the combo wrench around the torsion bar. I don't remember which way I had the angle of the box end facing. Just use what will work.

2.Then use the extension and the socket on the end of the torsion bar and push back so that you can get the combo wrench down past the curve, this is key. Once that is done you can remove the socket and extension. Pressure will push the wrench against the rear trunk wall.

3.Now comes the fun part. Push the wrench forward (VERY CAREFULLY) all the way past the side engine grill support and onto the peg of the hinge. The tip of my torsion bar just nicked the grill support. Make sure the wrench is seated well because it could slip around on you and cause your paint some damage and maybe even you.

4.Now that the torsion bar is on the hinge peg, you'll notice that your left with a wrench stuck on the bar... Just move (wiggle, twist) the wrench as far to the end of the torsion bar as it will go.

5.Take the extension, without the socket and place over the tip of the torsion bar. Push down while you slip the wrench past the peg. Remove the extension and slip off the wrench.

6.Now use the extension again to push down and put the roller (plastic, metal) bearing onto the peg.

7.Secure all the bolts, and lube it up.

That's it. Hope it'll help someone else. Please be careful.

most torsion bars ure under the least tension when fully open and have one bar facing right and one left
insert the fixed end in the bracket then with a suitable tool twist the end of the bar down as you put it in the hinge bracket repeat for the opposite bar
It is not easy until you get the idea as to how to twist the bar as you put it in place

See here p55. You will need to cobble up a tool which hooks on the bar, somehow.

Toyota refers to a special tool, see here p55

You can see how it works. I think an effective substitute could be mad from a length of hardwood with a dowel rod through it at right angles

Replace with a new or used one.

one of those bars come out of its bracket ( on my 89 cougar)
none of the local shops would touch it, no even the body shops.
so i just connect one end to the lid, like normal, then with a pry bar, pryed out the other end and put in a small block of wood (two by four) then released the pry bar. took another bite pryed it out again then added another block until i got the desired spring back into the torsion rod. yes that's (jury rigged) but my trunk works almost like it should. if you need i can send you a picture of what i did.
