I'm not going to insult your talents, but if it took you 5 hours, you definitely need more tools. It's an hour job at worst, seriously.
EDIT: That may have come across as rude, and I didn't want it taken that way. I had the rear of the car lifted, things may look markedly different if you weren't able to get the back end in the air. If you didn't have the back end in the air, then you definitely need more tools.
No rudeness, I don't have feelings to hurt. Verdict: I am slow.
I put the rear on jack-stands. The time consuming elements were removal of rear hangers (not a lot of room for hands and ratchet) as well as the removal and replacement of tie rods. This was done with a breaker bar with T40 and a box wrench. Once I got it tight, I used my torque wrench to get it to 76ftlbs.
I would be quicker now, but my tools are in the garage and basement. I had several trips. If I do much more of this type of stuff I may get an electric socket driver.
I already had pinch-weld friendly jack stand inserts (rubber). I don't have a crawler, so I was sliding around on the concrete driveway.
I did a short test drive... there is a difference. Much flatter when taking corner aggressively... I anticipate that if the back end kicks out it will do so with vigor now. I would do again.
The grey paint turned out wise, since the bar can be seen through the wheel and in the rear fender well. The bright blue would have been an eyesore for my vehicle. Blue would not match.
Happy wrenching!
Next project should be <1 hour. Adding the FP skid plate.
