Question Toe-in numbers

Hey all,

Here's what I have:

-2.5/2" springs (Fat Bobs)
-adjustable front upper/lower control arms
-1.5" RC wheel spacers
-255/70/16 AT2's on stock silverblades
-New TRE/Drag Link/Balljoints
-JKS Adjustable Track Bar

I had an alignment before I got the tires/spacers but now I have significant BS and DW. I had the caster set at 4.5 degrees per IRO contact from my last alignment.

I'll be going in for my alignment to be checked this Saturday and would like to know what my toe-in should be according to my assortment of parts. Any input on the specs I should be aligning to?

Thank you.

Roughly 1/16"-1/8" toed in.

DW isn't an alignment issue 98% of the time. Its a loose/worn component issue, causing the tire and/or wheel to move laterally when it shouldn't. I see you have almost all new parts up front, however. Is everything torqued properly?

Bump steer is a mismatch in angles from your drag link and track bar, caused by different arcs during suspension movement, unless you also have something loose/worn causing give during suspension travel.

I'd be checking track bar torque and making sure the frame side hole isn't oblonged. Could also be play in the sealed hubs possibly. Lots of possible causes.

I'll double check all the torque on every component tomorrow night. I had the hubs replaced right after the lift. Thanks for the input
