On a 40 Ford had a man set toe now it going down road right turns easy ,left turns seem to be a little grabby a little harder to pull sterring wheelThanks for help
 
It sounds like the toe is not set correctly. Radial tires should have 1/32 to 1/16 toe in, and bias tires should have 1/16 to 1/8 toe in. If a car is toed out it will wander and if it is toed in it will be squirrely or grabby. Good luck Flatmotor
 
I just had a similar problem i toed in a 52 f1 and it became worst.What I found was the kingpin was loose and after replaceing it, then tie in correct.It like a new truck now.
 
I put a new set of needle brg king pins in will take it to a frt end shop.When I started driving it 400 mile ago hade it done at a place he said was old school but he could not get it on his rack so we did it on a flat surface in his shop.
 
The steering gear needs to be "centered" in order for steering effort to be equal in each direction.
 
Are your new needle bearing king pins tight? Can you put a small level on the back side of the backing plates on both sides to see if the camber? is the same on both sides (the SAME- not backing plates perfectly VERTICAL?) Can you get the level on something to see that the caster? is the SAME on both sides? Finally, can you see if a line thru the kingpin axis and the tierod axis passes roughly thru the center of the rear end (Ackerman effect?) It's my understanding that a front end is messed up if the CASTER is off. CASTER is the axis of the kingpin off vertical when viewed from the side of the car and is what controls the steering tending to straighten out when the car is moving forward. If the caster is different on both sides of the car, that's when you chew up tires and have nasty steering. It's easy to set on a car with independent front suspension, but easier to mess up hitting a pot hole, etc. With a good ole Ford axle, it's harder to knock out of whack, but the axle would have to be bent to straighten it out. Also, the Ackerman effect is what makes the front wheels turn a little different on left and right so when you make a turn, the axis of both wheels intersect with the axis of the rear axle at the same point so neither of the front wheels will be dragged side ways when steering. You might be best taking it to a shop that specializes in TRUCK alignment. They should be able to check all this out and do what's necessary to fix it. This is all my opinion of course.
 
THat is the place I took it to a Truck alignment shop said he does it old schoolI have the orginal frt and rear end in this 40
