08 Prerunner rear axel adjustment

Hello TW, I don’t post often but I am stumped at this point. I have a 2008 Prerunner with 5100’s all around, SPC UCA’s, Dakar leaf pack with 3 degree shims, and the Timbren super bump stops and am having trouble adjusting the rear axel. At first it was way off towards the right and you could tell by looking at the driveshaft and differential. So yesterday I spent most of the evening trying to adjust the axel and center the Timbren mounting plates with the leaf center pins. At first I didn’t think it did anything b/c the driveshaft still looks off when looking at it. However after taking measurements (with a tape measure lol) it seems now that the axel is pointing left even though the front of the tires are the exact same distance from wheel well.... also the truck pulls to the right pretty bad now after attempting to adjust the axel. So if you guys have any tips or suggestions I’m all ears! Thanks!

 

...Ps I took the last measurements on the page from the leaf rack to the middle of tire (aka tiny line running down middle of tire) kind of hard to see in photo.

 

dont ever trust the bed for measurements... you can loosen bed bolts and shift things around a solid inch.

Measure from the same point on the frame on both sides to the axle itself (say from an identical spot in front of the leafsprings to the axle tube face just outside of the leaf spring perch)

So long as you have the centering pin fully seated in the spring perch there really isnt much adjustment you can do.
