Must II Problems

I have a 1940 Ford Sedan with Must II front suspension the car has always had real tight and sensitive steering. I recently rebuilt the suspension on the front, and replaced the power rack. I have a problem now with the steering almost feeling like it wants to lock up while turning. It feels like the steering shaft is binding on something but checking it out I found no interferences. I'm using an after market cross member ( unknown who manufactured it came with the car when I bought it) Original upper and lower control arms and strut rod eliminators that tie into the cross member. I've tried bleeding out the new rack thinking an air pocket possibly I have ruled that out. My next thought is to change contol arms and go to tubular ones. If any one has any Ideas that may solve this problem I would greatly appreciate it I would like to fix it before the summer driving season.

Make sure your steering shaft is not to far into the steering u-joints.If they are to far,they will bind up.

I would suspect the power rack. Do you have contact with any rodders that can point you to good front end shop, one that will take some time with your car?

The control arms are not the problem. As New Interiors suggests, check the u-joints on the steering to make sure the steering shafts do not protrude past the casting. If they do, there could be binding going on. Also make sure the u-joints are "in-phase" with each other; the U's need to be parallel with each other. If that's not it, suspect the power steering pump.

Let us know what you find.

Must II problems

Thanks for the input I will double check the steering shaft in the next couple of weeks, I also may have a problem with the belt slipping I have been getting a bad belt squeel since I had the crank and waterpump pullys powder coated. I'll let you know what I find in the next couple of weeks.

I'm thinking the same as Vince..If your u joints are not binding, return that rack for a new one.

Jack up the car, and with the motor off, try to turn the steering wheel. it should turn smoothly. If the u joints are binding, it will do it even with the wheels off the ground. you can tell u joints binding because they will get hard at exactly the same spot with each revolution of the wheel.

if there is no binding with the motor off, start the motor. If you experience binding and clunky operation and belts squealing, you may have an internal hydraulic valving issue in your rack..

Later, mikey

From experience, I would fix the slipping belt problem before I tried diagnosing other steering issues.

Good one
I, for one, assumed that the belts are already tight.

But you never know.

Problem Resolved

After much checking and measuring I found the problem. It turns out the Vibration reduction U-Joint went bad and was binding. It was not visible until I removed it from the car. It's been replaced and every thing is steering like new again. Thanks for all the replies.
