The only adjustment you will have is toe in. . There's no reason your caster will be off with the addition of a spacer. Loosen the clamps at each end of the tie rod. Check to se if you can actually rotate the tie rod or is it rusted in place. grab a pipe wrench and drive down the road until you get the death wobble. Note the speed when it occurs.I wonder if this is the case for me. I have a weird feeling that is what the problem is. Thanks,
Stop , get out and rotate the tie rod one revolution and repeat the drive. If it gets better you know your on the right track. If it gets worse, rotate the rod back one revolution to the start point and continue another revolution in that direction. Repeat the drive .
If nothing else , it helps you understand the relationship between alignment position and a stable front end. I run through this after every rod end swap
