Sunday I headed to the woods with my 15yo son and we put the Samurai through the paces. Mud, dirt roads, interstate, pretty much a little of everything. It's a much more versatile vehicle, but we did run into a problem. The YJ spring conversion pushes the front axle forward about 1.5". With the vehicle lowered, that was causing a binding issue with the steering linkage when the suspension was compressed.
To fix that, I dropped the springs, drilled the spring perches and moved the axle back 1". That solved the steering issue, but now the axle is hitting the oil pan instead.

This is apparently a common problem when a 1.6 engine is swapped into a Samurai. The fix is usually a 3+ inch lift or modifying the 1.3 pan to fit the 1.6 engine. I'm leaning more toward modifying the 1.6 pan to clear the axle. That will be next on the list.
I did twist the suspension as much as I could with my jack looking for other binding areas. So far so good there.
More to come as it happens.
