pull the cross member and check the dimensions. the shock towers tend to collapse in. it needs to be jacked out straight and reinforced. while your at it you can put new fulcrum pins and bushings in, new ball joints and bearings, reinforce the sway bar mounts, and maybe even change the shocks. you can also check the engine mounts (which should be new if its a new engine) and check the steering rack. also replace all the bolts with new grade 8 versions and use loctite on them.
sounds like a lot but its quite cheap and you can do everything together. its extremely important to get the new fucrum pins, ball joints and reinforce the shock towers and the like.
if you’re not a member of CAT it can be worth it to get the their shop notes for about $25 which is a mine of information.
when you’re all done you should be able to align it well. with the cross member out of line (which it will be unless its been done recently) you’ll never get the front end aligned.
