Here are some install tips for replacing the upper control arm on the Tundra.

Here is the stock setup. First, remove the cotter pin and ball joint nut (19mm). You may want to pre-soak with WD-40 (or better yet some PB Blaster) and use a persuader! |

This is the tuff part. Squirt some more lube around the bolt. With a ball peen or other hammer, start tapping around on the a-arm as well as the side on the top of the spindle arm. The Ball joint bolt is pressed on pretty snug. After letting things soak for about 10-15 minutes, you may need to start smacking in earnest! Eventually it will pop off. Or go out and get yourself a pitman puller and don't worry about it!!!

When the arm does pop off it will pop up horizontal. Now go for the long bolt in the back (19mm). Again a persuader will help immensely!! |

Getting the ATS A-arm on is cake. Insert the long bolt thru the rear bolt hole, align with the frame mount and push it thru to the other end. Once threaded I started the end bolt, then before I torqued it down , I also inserted the ball joint bolt and loosely bolted it. The long bolt should be torqued at 72 ft.lbs, the ball joint nut at 77 ft.lbs

Here are a couple of views of the new A-arm. In the middle comparison, you can see that the ball joint angle is somewhat improved over stock (on the left) at full extension, but not by a significant amount

Thats it!! Total work time, about 2 hours.
