Restoring Spindle Arm and Steering Gear Arm Balls...
How many of you feel comfortable in replacing/restoring the balls on the Spindle Arms and the Steering Gear Arm?
During my neophyte days of Model A Restoration (1966-68), I sent my Spindle Arms and Steering Gear Arms off to have "new" balls put on. When I got them back, they looked great. Fast forward to 1980 when I drove my 1929 Standard Coupe back from a trip to California and as I was just entering Bend, Oregon, I lost my steering! I almost soiled my britches on that one! Pulled into a gas station at the point of no steering and discovered the ball had seperated from the Steering Gear Arm. Using my MAFCA Roster at the time I called someone and they got me a Steering Gear Arm so I could coninue my trip back to Walla Walla, WA. From that point on, I have always tried to find good and unworn originals. Anyone ever had an experience like that with those "reconditioned" Spindle Arms and Steering Gear Arms? Even if you have done the job yourself...do you really feel comfortable? Pluck |

I don't trust something that's been welded to a cast steel part. I have built up the ball and then grind down the weld. It takes some time but I believe it saves the integrity and strength of the part.

I welded the 4 balls and filed them back to the correct diameter. Next time I'll just send them to A&L to have new balls installed on the shaft.

Re: Restoring Spindle Arm and Steering Gear Arm Balls...
My brother is my mechanic and he has done both welding the balls up then grinding back down and cutting the ball off drilling out the arm and welding the new ball back on.
5 years with some of both no problems no cracks...but I would not have done it myself with my limited welding I left it to an expert |

Re: Restoring Spindle Arm and Steering Gear Arm Balls...
In past years many clubs had seminars replacing the spindle balls. They would saw the ball and shank off and drill a hole where the shank was. A new ball and shank obtainable from most Model A suppliers was pushed through the hole and welded in place. This can be a very dangerous situation depending on how big the hole was and how bad the weld was.
A friend had a technique where he would saw the ball and shank off then mill a precision hole such that the new ball and shank would press in with an interference fit. he would then take them to a certified welder and have them welded. I felt comfortable with this process. Some time later an accident was reported in the Restorer where one of these sloppy seminar fixes failed and the person lost steering control. Bratton's Antique Auto shortly after took the ball and shank replacements out of their catalog. The reason being they did not want to be party to a possible law suite. A&L in New England came up with a much better fix. Instead of sawing the ball and shank off they mill the existing ball down to where it is even with shank. They then press a ball with a hole in it on over the shank with an interference press fit. The very top of the ball is then welded to the top of the shank. In this manner they do not molest the integrity of the original forging. When you buy replacement spindle arms from Bratton's, they come from A&L. I feel very comfortable with the A&L process and have installed them on a number of cars. Tom Endy |

Re: Restoring Spindle Arm and Steering Gear Arm Balls...
I agree with Tom W. and Tom E. about A&L reballing steering components. The technique they use makes a lot of sense. They leave the original shank and sweat on a hardened ball with a hole through the center. I can's see how this process could have flaws. I suppose there could be a problem with the inside part of the Ford component, but that would be extremely rare. I have had several done by A&L and have no worries about them failing.

Re: Restoring Spindle Arm and Steering Gear Arm Balls...
I lost a replaced ball on my roadster's pitman arm while coming down the switchbacks at the entrance to Arches National Park. I was okay after I stopped trying to steer and just jammed on the brakes. I bought a new pitman arm. No more ball replacements.

Re: Restoring Spindle Arm and Steering Gear Arm Balls...
Over the winter I replaced the three balls on front axle as part of a total restoration of 30 coupe. Used a new shorter Pittman to help dad steer. My method was cut old balls off drill under size, ream for light press, weld top and bottom with my mig, smooth out on grinder. I'm comfortable with my welding skill but now I'm wondering if I should have done this. The car has not been on road yet but will be completed this week. Maybe I should have had them stress relieved. Never thought much of it till reading this post thought these things were tried and true.

Re: Restoring Spindle Arm and Steering Gear Arm Balls...
I just finished my steering arm ball replacement. I machined the arm for the replacement ball shaft to a light press, installed a small solid cross pin, and had it tig welded top and bottom, and spot weld the cross pin.
Mechanically retained by the cross pin, and professionally welded. Don't expect this to ever come apart. KK |

Re: Restoring Spindle Arm and Steering Gear Arm Balls...
I don't want to take the chance of a weld breaking. I try to elminate any potential life endangering situations. After surviving a year in Vietnam, I practice "better safe then sorry". I buy new steering parts. It's OK if I risk my life, but not Ok to risk my children or grandchildrens' lives.

Re: Restoring Spindle Arm and Steering Gear Arm Balls...
I used replacement balls with shanks. My local machine shop milled off the old balls and drilled holes for the shanks. The welding was done by a local certified welder who has done a number of these replacement jobs. I wouldn't do this repair myself, but I feel confidant about this welder's skills.

Re: Restoring Spindle Arm and Steering Gear Arm Balls...
I think Bert's rebuilds them by using the machining down the old ball method.

Model A times mentioned a guy in Wichita I think his name was Francis Grady.
