is there a difference dimensionally between 2wd and 4wd front subframes?
i know that one is alloy and one is steel, but could you use a 4wd subframe with 2wd tca's and hubs? i have a 4wd subframe and rack but want to go 2wd and i already have the hubs and tca's. i am thinking that the 4wd subframe is wider hence why the wheels have a different offset.

come on guys someone somewhere must know.

A guy I know tried to do what your thinking and had a few problems one being the rack didn't have enough adjustment to sort the tracking out . That was 4wd subframe and rack with 2wd hubs etc. hth

Dojj will no but as far as i've read everyone who's tried ended up with grief

different rack, different steering column to rack, differing tca position, geo changes all over.
