Rear fender bender help

So i bought a 1999 323i with SP from a friend 2 days ago. solid low milage car. anyway, he got into a small accident some time ago, and there is a 2 inch crease dent below the left tailight. This doesnt really bother me. However this also caused the rear bumper to move a bit so on the left side at the wheelwell its not alligned anymore. I know how to take the back bumper off thanks to an excellent DIY on this forum however i was wondering how to reset the absorbers behind the bumper. or rather how to properly align and secure it in in original spot.

any help would be wonderful.

I just took off the rear bumper cover and bumper in order to reset the impact shock aborbers that collapse when you back up into a pole It took about two hours to remove, reset the shock and then replace the bumper/bumper cover. Here is how you do it:

Read it all before you start>

1. Raise the car up on jackstands. Carefully. Read up on how to do this correctly or you will damage your car and kill yourself.
2. Remove the wheels/tires
3. Inside each rear wheel well there are plastic inner liners, you want to remove the lower ones located to the rear. Do this on each side. There are 4 or 5 small fasteners of various types on each size. Take them out carefully so you can reuse them. Some are plastic, and you pry them oout gently with a screwdriver. Some are metal, 10mm and some are plastic 10mm. Your mileage may vary. This part will be easier if your car is clean so wash out the wheel wells. Its also a great time to detail clean out this area where a LOT of road dirt collects.
4. There is a clip that holds the bumper cover front edge to the lower rear quarter panel. Pre 9/2001 built cars, you take out a screw and then pull a "C" shaped hanger out. This releases the bumper cover from the quarter panel lower edge. ON post 10/2001 there is a clip that releases by pressing down.My 2002 with a build date of 9/2001 had the first type.
5. At the rear of the car, remove (pull it loose by releaseing some of the plastic slide in retainers) the lower trim panel on the bumper cover. This allows access to 2 large bolts that go through the bumper cover, and secure it to the bumper itself.
6. Remove the 2 large bolts. They are located under the bumper, about 8inches in from each end. It takes a T50 torx. I used a Sears 3/8" drive T50 socket.
7. Lay a blanket behind the car across the full width of the car. Get a friend it you have one.
8. Pull back on the bumper cover and slide the whole thing back, watching to see if there are any screws you forgot or wires (like for park distance sensors ) that you forgot to unhook.
9. Place the whole thing, which seemed to weigh only 20 pounds or so on the blanket gently.
10. You are done
11. Reassembly is the same in reverse.
12. Any questions, see your body shop
13. This was relatively easy, but dirty"
