2004 Infiniti QX56 - The Height Of Luxury

Pro Comp's 3/16-inch-thick steel fabricated crossmembers bolted into the lower control-arm mounting holes.

With both Pro Comp crossmembers in place, Brian reinstalled the factory lower control arms.

An improvement in looks and performance, Pro Comp's coilovers were bolted in by using the factory mounting points.

Both 2WD and 4WD Nissan and Infiniti hubs were bolted on, rather than pressed in, which made switching them much easier.

A screw jack was used to lift the lower control arm to mount the spindle into the upper control arm.

Compression struts were mounted with the supplied polyurethane bushings into the rear crossmember. The opposite bracket was bolted to factory holes in the transmission crossmember.

This gold iridite adapter and longer end link were used to mount the factory sway bar to the dropped lower control arm.

The addition of braided stainless steel brake lines and new bumpstops completed the front suspension.

Moving to the rear, six bolts held the IRS subframe to the rest of the frame. They were very difficult to remove, as Brian had to use a breaker bar to pry them loose.

Next, the compressor for the auto-leveling rear suspension was unbolted.

With the entire rear suspension assembly supported on jacks, Jesse was ready to attack the evaporation canister.

An abrasive cut-off wheel was used to remove the canister from its bracket.
