Hi Ron,
Suggest the following (it worked very well for me).
1. Remove the hex-bit you have on the adjusting screw. (it shouldn’t be there!).
2. Loosen the motor mounts bolts (without taking them out!) until they stand proud of the engine brackets about ½ inch.
3. Use a floor jack with a piece of timber about 2X10X5” under the oil pan and jack up the engine about 1/2" inch. This will give you the clearance for the socket with the 6mm hex-bit between the adjusting screw and the engine block.
4. Obtain a 10mm 3/8” drive short socket and a short 6mm hex-bit with 10mm wide end. 2 short 3/8” drive wobbly extensions and 15-17” long ratchet extension bars and 2 3/8” drive ratchets (see pics).
5. Insert a 19mm crow-foot socket with the wobbly extension and long extensions between the exhaust manifold and the cylinder head just above the steering box with the crow-foot socket to your left. Wrapt a tape around the 6mm hex-bit to tap tight into the 10mm socket so it will not get stuck like the bar you now have on the adjusting screw and the 6mm hex-bit on the extension bars on the adjusting screw with a bit of oil on the 6mm bit so that you can withdraw when adjusted. The locking nut is very tight on the adjusting screw and a squirt of penetrating oil will help. Turn the adjusting screw ¼ of a turn to the left (unscrewing motion) and tighten the lock nut. Test the steering with the weight of the car on the wheels and repeat until you obtain ½” to the left and ½” to the right on the steering wheel (total 1” play is the norm).
The adjustment should be carried out after you replace the steering idle bushes which is very easy to replace. Remove the bolt and notice there should be a washer between the top bush and the steering arm linkage. Start with the bottom bush removal with a screw driver to pry it out and a pair of players to remove it. With the bottom bush removed insert a 19”mm socket ½” drive on an ratchet extension and either tap the top bush out or push the extension with a floor jack. The new bushes are installed top first using the old idler bolt as a tool smearing sliding KY jelly or similar on the bush, then the bottom one. Tighten the bolt to 70 Nm. Hope this helps.
