Default Steering and tire pressure

Having just redone my model a steer box rebuit tight no binding shortened pittman arm synthetic grease teflon cups on drag link and and tie rod all ball are round and not worn. I have the car up on jack stands it seems a little stiff maybe because everything is new and snug but car turns from side to side no binding and is easy to turn. I am thinking air pressure could help this some i believe standard is 35 psi my tires are firestones could one bump the pressure a little. Also would radials help this? This is a 1930 tudor with standard wheels what size would you recommend.

bnchief, I would leave the tire pressure as is at 35 psi. Over inflating would make the steering seem easier when not in motion, but would guickly wear out the centre tread of the tire. Just my thought. Jeff

The wider the tread, the stiffer to turn. One should only turn the wheel while the car is moving.

Do radials turn better than the regular tires

I wouldn't say that the radials "turn" better. They stay on the road better. They hug the road on long curves better, rather then "feathering" into another lane. They do aid in emergency braking, as they will adhere to the road better. As opposed the sliding on top of the road surface. Again this all differs in different weather conditions..... Hope this helps. Jeff

I know I'm a "foreigner" here and that English is not my best language, but I'm reading this post for the past 5 minutes and I still can't figure out exactly what you mean !

3.6 I assumed people knew what i was talking about for instance steering box was totally rebuilt and adjusted, I used the teflon cups in the drag link and the tie rod also front end was completely rebuilt and I put it on jack stands to see if it turned smoothly with no binding and it does it seems it could steer a little better but everything is tight so tires are my next question if you have more questions feel free to ask that is what the forum is for.

Wayne I have driven the car it steers straight does not wander just seems a little stiff need to follow up on tire pressure these tires are old but do not show and weather checking.

Drive it @ 35psi. I am sure u checked the king pins and thrust bearings, and have the box set to specs..
Agree with Jeff above about over inflation..

My opinion,would be leave tire pressure alone .If you were driving a with a tired front end ,and now everything is brand new it might just take a little time to get used to it. Could you possibly loosen the adjustment nut that puts pressure on the worm gear?

Steering box is rebuilt and adjusted with all new bearings and worm and works very smoothly and has 600w oil as well these all turn very smoothly and freely with car on jack stands i followed les andrews book to the letter And yes mitch front end completely rebuilt and checked as per book spindles are a little snug but can be turned easily I put the car on stands to see if i got any binding or hard turning smooth feels like it has power steering. Car on the ground a little stiffer maybe my tire pressure is not up to what it should be i will check that next.

I personally like to shorten the pitman arm. It makes a world of difference on my cars about the effort it takes to turn.

There are a lot of things that can cause tight steering. If you've redone the box and it is smooth on the bench.... then hopefully that is out of the equation. As Mitch stated 35PSI should be good... and yes you have to gauge steering when moving.
Other items include:
1. steering balls and end plugs... I Highly recommend the steer-eze kit adjusted properly
2. as Mitch stated the spindle bolt load ( must be properly loaded and shimmed if necessary - can have a great impact
3. proper toe in - please make sure it's checked with an accurate tool. There's lots of inaccurate methods touted but I would use an accurate toe in gauge or take it to someone who can accurately check it. You would be surprised how much difference this can make.
4. make sure your front spring isn't sagging which if severe can cause the drag link and tie rod to rub. Many original units have evidence of this.

5. proper lubrication on all components including spindles. The spindle bolt loading and bearings are key here. with the car down if you can rotate the spindle bolt bearings it is not riding on them.

Check all the above and hopefully you will find something to fix and improve upon.
Keep us posted!! Maybe post a pic or two of your front end.

To add onto #4 of Larry's good list..
Make sure the tie-rod is not rubbing the drag link.. a sign of a weak spring
