If your steering wheel is getting hard to turn and won't return coming out of a corner, the lower steering shaft may be the culprit.
The lower steering shaft connects the stem of the steering column to the rack and pinion unit.
This is a short shaft that contains two small u-joints which due to their size,
can't be equipped with grease fittings. (I agree- lousy design)
The shaft is expandable to ease its installation. (stop laughing)
Please excuse the pictures,
I'm not sure why they load so big.
There are two bolts that secure it in place, the upper bolt is 13mm,
the lower is 10mm.
Turn the steering wheel so that the lower bolt is facing the radiator to allow you access.
(Spray Liquid Wrench or PB Blaster on it now to help remove it later)
To keep the steering wheel in proper alignment,
I installed a pair of vise-grips to hold the upper shaft stem.
(This will turn on its own if you don't do this).
>>>DO NOT FORGET TO REMOVE THE VISE-GRIPS WHEN FINISHED.<<<
Once the upper bolt is removed, pull the top from the upper stem.
At this point compress the shaft and push the top under
the radiator fluid supply hose, (it's tight, but it will go).
Now comes the tricky part, the lower connection will probably be rusted to the shaft.
If you look closely, there is a slot where the bolt clamps this in place.
I hammered a screwdriver in to loosen it, (your long 1/2" socket extension or a piece of pipe helps).
>>>Leave the screwdriver in it to ease removal<<<.
If you remove the screwdriver, the metal closes just enough to make it difficult to remove.
The shaft removed, screwdriver still in place....
Next I wire brushed the end of the upper shaft.
Wipe the rack and pinion post, and apply some anti-seize to both.
Install the new shaft under the radiator supply hose, bottom first.
Good Luck...this took me about 1 1/2 hours to complete.
