Default PSCV replacement 1969

So one last question for today, i am about to replace the power steering control valve and ram. I have a new unit ready to go with some heavy duty jack stands. I found an excellent video of the change out on You Tube, but, I understand the cars wheels have to hang freely and the car started to calibrate the PSCV, so
Where do I safely put my jacks. I did lots of reading and looked under the car but can't find a good place to put them knowing I will have to run the car to set the PSCV.
I searched the forum but couldn't find a good reference.
Thanks for any advice.
Pete

OR, do I have this correct, maybe the wheels can stay on the car and sitting on something supported???

I remove my wheel to get better access to the adjusting nut. Place your jackstands on the side frame rails in the area a few inches forward of the front door seam. The frame rails actually curve slightly upwards just forward of this point so you must make sure your jacks are not positioned there. Poke your head under there to make sure you have them in the right spot.

Thanks, I was trying to put them up front along the line of the wheels,,
Thank you so much, I will put some safety blocks there instead and have the jack stands as you say.

Remember not to reach thru the steering wheel when starting car.
Good luck

I will not do that!
but I did get the car safely on jack stands and removed all the hoses with no issues. I now try to disconnect the PSCV from the pitman arm but I just can't remove it.
I have tried and tried, why is it so damn tight, shouldn't it just slide off the top? I have a pickle fork which is says NOT TO USE in the instructions.
Any ideas, do I need some type of puller instead or shall I just bang on it harder!
Thanks, Pete

why wouldn't you use the pickle fork on the old valve? The fork with a few taps with a large hammer and the valve comes off.

Pickle Fork it is then!!
I have no idea why they say not to use it in the instructions, maybe they want to keep the old one in good shape.. I don't care, I have a new one waiting on the bench!
I have never done this job before, here it goes!!

Just an update, PSCV and new RAM installed as of 3 days ago. First time on that job with no help other than youtube and corvette forum. Works perfect now, I now have power steering and no leaks on the garage floor.
Thanks for all the help!

Nice one, can you link to the youtube video and forum posts in case anyone wants to do the same some time in the future?

Cheers.

Here is the you tube link to the change out. Hardest part was getting both wheels off the ground, after that it was easy but definitely remove the front drivers wheel for easy access.


I bought mine at Lordco which is in British Columbia only but equivalent to a Napa or Auto zone. I believe the same ram cylinder and PSCV is used from about 1963 to 1978 and likely on many cars other than the corvette so they are easy to find.

Wilcox or Corvette Central have them for about 100 each rebuilt plus core charge.
Wilcox also has a great video on rebuilding the PSCV if you feel like saving a few bucks. I would have but have just too many things to do on my car and just didn't have the time.

It is about a 4-6 hour job for me and probably less for someone who has any idea of what they are doing.

Best of luck
Pete
