Pain in the butt. Installed while chasing a steering noise. Good rack, but I didn't actually need it.
"Clunk" noise turned out to be under-torqued lower control arm, possibly from previous owner installing suspension. That fix was free, but my $250 second guess at the problem was not.
Good news is the car now has a low miles steering rack, fresh power steering fluid, and all new tie rods except for pass side outer
