A little off topic but it may help you.

I had a customers car a few years back that complained of the steering "locking up solid".

Car came in on a towtruck.

After a bit of testing, could not locate the fault, but sure enough during a roadtest, it went solid.

The intermediate coupling was not on the rack far enough and was forcing a u-joint to go through too much angle.
Vehicle had a rack fitted after accident damage by another repairer.

Took about 15 minutes to sort.

Moral is: check all the u-joints are not going beyond about 30 degrees.
