I made my own steering shaft using 3/4 inch DOM.. sleeved it to fit with the original toyota adaptor that bolts onto the steering box..I need to add a steering shaft u joint but I didnt put any slip into this system... everything is welded together

1)Does the steering shaft(system) need to have slip movement

2)How much is typical movement for a steering shaft

3)If the whole shaft is hard welded would it be sufficient to just add a little extra at the steering wheel and allow the steering wheel to move up/down(back/forth) whatever or would that kill the shaft u joint etc

Thanks

you need some slip because the body moves seperate from the frame, i would think that there would be about 1/4-1/2 inches of change when you flex out.

it needs to have movement or yer gunna push the colum outof the firewall. like said above the body flexes different angles then the frame so it would be pulling and pushing. if you wanna make yer own your best bet would be squar tubing

Same as above plus if you have the occasion to stop really fast by running into or being run into, you have just created a "chest spear". It needs to have the ability to collapse in a collision. Just my $.02

X2 on the collapsible issue, but only if street-driven or high speed off-road.

the body is rubber mounted. you should never mount any thing stiffly between rubber. so yea it needs a slip joint or somthing of the sort.
