Hey'all,
Been a while since I've been on here. I'm looking for some advice dealing with some suspension issues.
Truck is a 1990 D150. I picked it up a month ago as a new daily. When I got it home, it had a hard lean to the driver side front. I know this is not uncommon. I replaced both rear leafs with new, and 100% of the front suspension and steering components, including new coils up front.

Once it was all back together, I found that the driver side is still sitting about 1-1.5 inches lower. I realize there is an arguable weight imbalance in the design of the truck, but still a bit surprised. Last night I was dialing in the alignment, and I found a couple of anomalies. Firstly, the driver side tire appears to be further outboard than the driver side, camber is dead on. The body measures within 1/4 inch left to right, so I don't think it's a body alignment issue.

One idiot move I made was to pull the LCAs off an throw them into the pile for new bushings and ball joints. Upon installation I assumed based on visual inspection that they were interchangeable, but based on the Chrysler part numbers, they are different. Can anyone explain the difference, if any, in the LCAs? When I am looking at them (installed) from the front, it appears that the driver side is tilted towards the rear, where the pass. side appears fairly level. As the truck is new to me, I'm not sure if they are OEM, but both have a stamp on them just inboard of the spring perch on the top of the arm. One is D411 and the other D416. These numbers don't correlate with any of the other LCAs I have around the yard.

Trying to rule out whether they are on the wrong side, or if one of them possibly took a hit and is no longer straight. Visually there is no sign of damage. I've been driving it a few weeks now and it was great, just wanted to dial in the caster due to a slight steering bias. Now I am back to square 1, and I don't want to finish the alignment if I have bigger issues to deal with.

Would appreciate any advice.

Thanks.
