Bad shake/wobble in the front end
So a buddy of mine and I finished a D30 swap in the ranger and everything seems tight and good to go. For a little while its been pretty good, but up until recently I've been getting a bad shake/wobble in the front end at 40-45mph. After that the front end settles itself out im guessing cause the tires are spinning so fast. I look out the window while its wobbling and it looks like the tires are moving side to side on its own. Tires are brand new and balanced. I checked every bolt I can think of and also the power steering box bolts. Just changed the upper link bar bushings. I just cant think of what else it could be? Castor too far out? Alignment jacked up? Or is the whole front end just going to fall out from under the truck one day haha.
HELP / suggestions would be greatly appreciated
