Tie rod placement question
I'm doing a frame off on my 66 Convertible and when I removed my tie rods (which were original GM's) the LH threaded ones where to the steering arms left and right. I noticed in Long Island Corvette they show the LH threaded tie rods going to the LH steering arm on LH side of car and the other LH threaded tie rod going to the center link on the RH side of car. Does anyone know where the factory placed these, the AIM doesn't show since they were supplied as an assembly. Thanks sincerely Brian

Brian,
I believe the right hand thread is outboard on each side. -
Re: Tie rod placement question
Functionally makes no difference. But I thought the RH threads were to the right & LR threads were to the left. Object to turn for adjustment in the same direction to take up or draw in. I don't know of any judge that regularly checks the direction of installation.Comment

My 1965 has the left hand thread to the outer steering arm position on both sides, with the right hand thread at the inner position.

This is a link to a paper that I wrote six years ago. My sketch at the end of the paper shows LH threads on both outboard tie rod ends. Both inboard threads were RH.
The paper also goes on to explain what the AIM is saying with respect to the orientation of the clamps and other things shown in the AIM. From a functional standpoint it doesn't make any difference. However, the car or truck assembly plant had automatic (or manual) toe set equipment and had to have the tie rods extending and retracting with the rotation of the tie rod sleeves in a repeatable, expected direction. So by convention the outboard ends were always LH.

After looking at everyone's reply I now believe my original's were correct with the LH threaded ones to the outside. I know it's not a judged item, but since I'm doing it I would like to get it as right as possible. A BIG THANKS again for all the help and opinions!!!!! Sincerely BrianComment

Re: Tie rod placement question
Buried in Jim's linked paper is mention of the direction the clamp nuts are to be installed. I don't know if mid-year chassis judges are onto that, but I can tell you the early C3 judges are. That is an easy-to-identify Installation deduction.TerryComment

Re: Tie rod placement question
The parts store books have always been wrong and this information has been picked up by just about everybody and published. It should be like Jim says.Comment

Re: Tie rod placement question
The Chassis Service Manuals often missed assembly tips and torque specs on assembled parts that came directly to the car assembly plant. The steering arm to knuckle attachment comes to mind. Since the arms were shipped preassembled, you cannot find a torque spec for those fasteners in the AIM (nor in the Chevrolet service manual.)
Saginaw spent a lot of time and money creating their own service manuals for assembled parts that were shipped to the assembly plants. They were given to their car and truck customers for reference. The various customer service departments were pretty good at using the Saginaw manuals to augment their own service manuals.
I am lucky to have saved a fairly good library of Saginaw service manuals (late 60s to early 80s, i.e. the C2/C3 years) from my career at Saginaw Division, Product Engineering.
