68 Camaro, I have installed a new power steering gear box , but the 3 spoke steering wheel is facing up rather than down. What could be the problem?

My guess is the 2 bolts at the rag joint are 180 degrees off, unbolt, rotate and re-install.

Some of the rag joints are actually made with the flat spot 180 degree's off...either pull the steering wheel and rotate 180 or pull the rag joint and replace with an american made one :-) ,do a search for rag joint problems.

If the steering gear with a flexible coupling was the only thing changed, (for example, you didn't have the steering column rebuilt or the steering linkage or tie rods changed) then we can pretty well expect that the problem was the new gear/flex coupling combination.

I am a lot more familiar with the 1969 and later Saginaw locking steering columns. I note that you have a 1968 F-car. I think that your turn signal cancelling cam is a part of the steering wheel and hub. If this is the case, you should be able to place your gear on center and then just rotate your steering wheel 180 degrees to fix the problem.

You cannot do this with a 1969 or later column where the turn signal cancelling cam is built right into the steering column itself.

The following paper gives a pretty good analysis as to why and how to fix an upside down steering wheel problem. It could get you to the actual root cause of your problem.

I might add that recently there have been some "new" flexible couplings used on Corvette manual gears that have had the gear flange incorrectly machined. The flex coupling is not a Saginaw OEM part. Because the flat in the gear flange is machined on the wrong side, what happens is the coupling causes the steering wheel to be upside down. Since I can't audit everything that is being sold across the country, it might be possible that there are other parts that are not correctly machined as well.

BTW, it is most helpful if you can provide a little more information on your car. Power or manual steering? Standard (non-adjustable) or tilt steering column?

Good luck,
