How far in can I screw those bolts that stop you from over turning your steering wheel on full lock, sorry I don't know their correct name.

One fell out so I took out the other to match it up, I don't think I screwed in either far enough as it now turns like an aircraft carrier.

Thanks.

The manual on page FA7 says to use a rotating angle gauge like a wheel aligner uses.

Only way I know to correctly adjust the steering lock stop bolts is on a wheel aligner machine after you have set up the toe in angle you measure the wheel angle on full lock.
Should be 30 degrees IIRC.

The dodgy brothers way is to set up steering straight ahead and count the steering wheel turns 'lock to lock' or the clearance on the radius arms. and make the replacement stop side the same as the original side

Too much angle and you can...
hit the radius arms with inside of tyre
stuff the steering box
chew out the CV's
...or any combination thereof

edit... mudnut posted while I was typing so 31 and 35 it is (not 30)

that all sounds too darn hard. Think I'll get them to look at it next time I have a wheel alignment.

Thanks guys.

Nah, not that hard... I've done it a few times over the years.
Turn full lock onto the stop that stayed in place, eyeball the radius arm to tyre clearance, full lock the other way, adjust if needs be but if you don't want to even do that... set the replacement bolt and locknut to roughly what the other side is (count the # of threads) then it is usually close enough till you get it on a machine

Thanks ET, I'll give it a go.

And thanks mudnut for the info posted as well.

Some more info regarding the steering stop bolts.
My turning circle has always been abysmal.
I found the passenger side stop bolt had come loose and the bolt and knuckle flange thread were damaged but salvageable.

85946.

I cleaned the bolt thread up with a die nut, cleaned the the remnant bolt threads out of the knuckle flange with a scriber and finally a spiral tap, blew the swarf out with compressed air, installed the stop bolt and cleaned the crud off the knuckle so the grease seal did not have to deal with the crud.

I set the stop bolt such that when the stop bolt is "bottomed out" the axle shaft does not interfere with the flange grease seal causing it to fail...

My turning circle is now somewhat improved following adjustment of both Stop Bolts.

For reference the bolt and lock nut are M12 x 1.25 - Metric extra-fine - These are not available at Bunnings. They can be sourced from a specialist bolt or engineering supplier or, possibly Blackwoods.
Note the head of the Nissan supplied bolt is convexed and will not be an off-the-shelf item, even at a specialist supplier, the reason Nissan charges hefty prices for replacements.
