I have just over 21,000 miles on #10901. I've had it a couple months. I noticed a clunk in the rear and knew I should check the TA bolts. Sure enough, just by looking at the rear right bolt, I could see that the shims weren't lined up anymore, and I could move them with a screw driver. It was also apparent from looking at the nut that there was a lot less threads showing on the right than on the left. The left looked still tight. I turned the bolt head and watched as my trailing arm moved up and down due to the bend in the bolt. I tightened up the bolt to spec, and ordered replacements right away. I also ordered the bushings. (all from PJ Grady...thanks guys!) As soon as I got my parts, I pulled out the old bolt and noticed that it DEFINITELY bent. I did have to use a hammer to get it out. The new bolt went it great and had a lock-nut with it too. I put on the lowering springs from PJ Grady (thanks again guys!) and took the car to get it aligned. The alignment went great. The front toe-in was a tiny bit off, but everything else was perfectly in spec. I will replace the other TA bolt even though it was still tight just to be on the safe side. My suspension feels MUCH better and almost all rear clunking is gone. ALMOST...hmmm....axles? I need to do some further investigation... Moral of the story....ALWAYS CHECK YOU TA BOLTS! And you may as well just replace them with the new stuff regardless and make sure you get lock-nuts. It's VERY CHEAP INSURANCE considering how important those little bolts are! Your life is worth a few bucks and 30 minutes of your time.
