The blue splined shaft should be able to move a couple of inches to
accommodate body motion. Disconnected at either end, the shaft should
separate there into two parts. So, yes, after REMOVING (not loosening) the
lower clamp bolt the shaft should compress enough for the u-joint to come
off of the steering box input shaft.
Unless you're VERY careful, you'll likely reassemble the upper CV joint in
one of the 5 incorrect positions rather than the one correct one, leaving
your steering wheel cocked. Nonetheless, removing both the upper and
lower clamp bolts, removing the complete lower steering shaft, and
refurbishing/lubricating the whole thing is a good idea. The lower U-joint
is VERY difficult to grease while in place (can't remember WHEN I did
mine). And the blue shaft probably doesn't get hit with grease nearly
often enough.
As we've said before, MARK THE CV JOINT carefully before disassembling it.
And after you've cleaned it, I STRONGLY recommend that you lubricate it
ONLY with Valvoline Synpower grease (for which we were given a new name
here recently). Other greases MAY cause binding in that device.
