Thanks Fanboy. That has been in waiting while I got some work done on the XJ.
Time for an update. Went with the 8.8 and the TrueTrac. While that was happening, went ahead and installed new ball joints, u-joints, tie rods, steering stabilizer, upper control arm bushings, new brake pads front and rear, extended brake lines, new track bar, sway bar discos, radiator hoses, changed all fluids and filters, banks monster exhaust, battery terminals, H4 headlight conversion and wiring harness, and 4.56 gears. Both axles also got new bearings and seals. Still have a Banks torque tube to install. Was going to tackle that Monday, but upper radiator hose split so had to deal with that. Decided to replace the lower while I was at it and deal with the broken stock negative battery terminal and the problematic IAC. I will try to get some pics posted tomorrow. Life is ridiculously busy right now. Need to get trailer and XJ ready to get out of town and off the grid for a few days.
