On top or even mid perch, the front tires lean in a lot. The top of the tires is much further in than the bottom. It's causing bad tire wear and has a negative effect on the handling on the road.
Is there any way to fix this. I didn't see any adjustment on the upper control arm.
You may have bent spindles. Based on your driving reputation, it would not surprise me at all. Even a minor bend in the spindle ear (one you can't see) can throw off the alignment. My LCAs were pulled all the way and I still ran -1.1 camber or so on
mid-perch. Replaced the spindles, dropped truck to the ground and I instantly had positive camber (more noticeable than the excessive negative camber I had before). FYI, I am now effectively on top perch or very close to it (ICONs), lower arms are pulled out, and my truck is easy to get into spec.
You can buy adjustable UCAs (Outlaw, ICON, etc.). I did. They can give you a little more flexibility on dialing in that alignment if you are on the top, but not really necessary if your problem is the spindle.
The camber kits will help the tech dial in an alignment and hold it once it is set, but they do not give you "extra" adjustment. The mounting slots for the LCAs are what they are. In other words, if your spindles are bent, camber kits are not going to help. They did not help me. FYI, some people think the camber kits are bad (prone to shearing the bolt apparently). I will leave that to the experts. They definitely hold the alignment, even when offroading hard, but maybe that leads to the shearing instead of just letting the alignment slip. Again, experts, feel free to weigh in.
Read Pirate's post. Great stuff. He helped me initially diagnose my problem (along with Moto, Outlaw and ICON). Very grateful for his help (and everyone else too). I bet he responded to 10 PMs from me. Thanks Pirate!
As to tech selection, Hock is right. Very important. I finally found a good one. He has my truck dialed in to Pirate's suggested specs. So nice to drive a truck that doesn't fight you or destroy tires.
Finally, I bought Outlaw's gussets for my new spindles. Only $99 for the gussets plus their welding charge. Outlaw bought the new spindles, welded on the gussets and sent them to me. Great service. A little extra insurance for not much incremental cost.
Hope this helps. My alignment issue drove me crazy for months. PM me if you have any questions about my issues or fix.
