Yep, 4x2 is IFS (Independent Front Suspension) with rack and pinion steering.
On a 4x2, the old shock comes out from the bottom and new shock goes in the same way. On mine I wasn't able to cut the retaining strip once the shock was installed; therefore, I cut the strip before installing, raised the front high enough to feed the expanded shock up through the coil springs from the bottom and attached the top nut to hold the shock in place. (The top nut and locking nut are accessed by reaching over the top of the front wheel/tire). Since the shock was expanded, I used a bottle jack to compress the shock enough to install the nuts on the bottom studs.
No gas wrench necessary. :-laf
