STI Pinks spring install on 06 TR sedan
I did this on my 06 TR so not all information may be valid for other years. I am providing these tips for information purposes only. I am not responsible for anything that happens as a result of someone reading this thread. Proceed at your own risk.
Jack and Jack Stands
Electric Torque wrench (rated 240 ft/lbs)
6mm allen wrench
12mm, 14mm, 17mm deep socket
17mm pass through socket
19mm impact socket
25" breaker bar
Large and small torque wrenchs covering 10-150 ft/lbs
flat head screw driver
spring compressor (rent one from an auto parts store)
Let pb blaster soak on the lower strut bolts over night.
BEFORE JACKING UP THE REAR
1. Remove the rear seat.
2. Remove the seat belt tensioners w/ the 14mm socket (not necessary, but makes life easier).
3. Use the 12mm deep socket to remove the locking nuts holding the metal cover down to expose the top strut bolt.
4. Use the 17mm deep socket to loosen the top strut nut(do not remove the nut, just 1-2 turns to loosen). The weight of the car helps make this easier
5. Repeat steps 2-4 for the other side.
JACK THE REAR UP
6. Remove the brakeline by removing the clip
7. Use breaker bar with the 19mm impact socket and a 19mm wrench to break the bolt free. I loosened the bolt side. If the strut is shifting around, use a floor jack to support it.
8. Remove the nuts, don't take out the bolts yet. Hold onto the strut before removing the bolts, otherwise the strut might fall and damage things.
9. Take out the strut and note how the top of the strut aligns with the bottom.
10. Use a spring compressor to compress the springs
11. Use the 17mm pass through socket and the 6mm allen wrench to remove the top strut nut.
12. Remove the spring, decompress the spring.
13. Compress new spring, and put back onto the strut.
14. Align the top of the strut and tighten the nut with the 17mm pass through and allen wrench.
15. Decompress the springs and reinstall the entire assembly onto the car.
16. The torque specs for the bottom strut bolt is 162 ft-lbs, top 17mm strut nut 41ft-lbs, and 12mm nuts are 14.5 ft-lbs. Becareful not to over torque the 12mm nuts, broken bolts can result. It is recommended to use new self locking nuts.
17. Repeat steps 6-16 for the other rear strut.
18. After both strut assemblies are installed and torqued, put the brake line back on and reinstall the wheels (around 66ft-lbs for the lugs).
