Anybody know if there is a procedure for
adjusting a manual steering box for a 70 Boss? The one on my car was replaced about 8 years ago - but the car has been driven less than 5K miles since. The steering is very tough and I don't know if it's normal for that type of car. That's why I was wondering if there is a procedure for adjusting the box. On a side note - how can you add the photo of your car to your login name? I have read messages posted by others and see that there are links to pics of their cars and I would like to do the same. Thanks

The only adjustment for a steering box is the sector shaft preload. That's is the stud and nut on top of the box. You loosen the nut, place an allen wrench on the shaft and adjust it down until you feel it contacts the top of the sector shaft. There's actually a torque setting for the tightness of the stud, but I don't have it handy. I can get it for you if you need it. But this adjustment won't reduce steering effort, just remove some play if present.Normal manual steering does take a good amount of effort. How hard is it? Lubing the steering components should help some. ------------------

I`ve driven a couple of 70 Boss 302`s with manual steering, one with F60-15 Polyglas, the other with 235 60R15 radials, & they both were very heavy in steering effort. I suppose the quick ratio box along with the wide tires comes with a price. As Arnold would say: IT WILL PUMP YOU UP!!!!! If you drive in city traffic much, yuo`ll soon have arms like Popeye!

They don't call it Armstrong steering for nothing.  It could also be an alignment problem. Too much caster will make it harder to steer. Our '66 is a handfull in a parking lot. You have to drive it differently, make your turns while the car is rolling and not stopped. Feels like you're gonna break the steering wheel right off its spokes when the car is stopped.  SteveW

It's pretty tough - but I can see by other
postings it may be normal. It's been
years (decades actually) since I have driven
a manual steering car so I have anything to compare mine with.
I lubed up the front end - everything except for the upper control arms. I couldn't get my
grease gun to fit. Have any tips for getting to those? Now I see why people used to cut holes in the shock towers. ------------------

If you are REAL lucky, using you use a small box wrench and lots of care you may be able to remove the grease zert and then install 90 degree grease zerts. If you can't get them off/out, you will have to go thru the steps necessary to remove the entire upper A-arm to get to the zerts.
