hi there - I have just upgraded from a generator to an alternator on my 57 - running a 350. As part of the process I had a new power steering pump installed and new lines to my original power steering installed. Nothing else was done. On driving home I noticed that when I took my hands off the wheel the car veered to right each time.

Is this something to do with pressure in the power steering box - I can't see that it is wheel alignment as nothing was touched and it was not doing this prior to the installation of the new pump. Appreciate any advice anyone has - many thanks Gerard

Is this the gear box type of power steering or the ram type on the steering linkage?

I would suggest getting a rebuild kit for both the cylinder and the valve that splits the pressure.

There is an adjustment under the end cap and not much is needed to change the flow. Sounds like you have some residual pressure bleeding over.

I've rebuilt many of these and the adjustment is key.

It may just need to be bled. Get a service manual. If you need help, contact member Jalapeno, a real expert that rebuilds, services, and sells steering. Don't get off on a tangent based on hear say from non experts that have NO experience.

I had that same thing happen on a 55 Chev., put in a rebuilt control valve and switched the pressure and return hoses, the fittings were the same size, started it up and it yanked to the right.

did you do the work yourself? if not whoever worked on it may have adjusted it

70 L camino, grampa engine, g-force 5 spd, road rage suspension. Pray first before all else fails.

Put the front end up on jack stands, wheels off the ground. With the steering wheel centered, start the engine.

If you have a pressure imbalance the steering wheel will turn to the side where the pressure is going. The adjustment I referred to earlier (if needed).

If the steering wheel stays centered, then the power steering is not contributing to the problem.

As far as "experts", I am not sure what exactly qualifies as such. If you owned an auto dealership with repair facilities for 20 years, would that qualify?

Not necessarily. No, if the brand was your screen name, which doesn't fit here.

Check out other posts. He thought that the wood decking in 55-57 wagons was optional. Check out the Monte Carlo thread "70 SS GM research vehicle", talking about catalytic converters. Also the 1929-1941 Chevy thread "37-38-39-front suspension/rear diff Frame's Centerline?", bad advice there too. To mention just a few -

A quote from his own bio:

'I am a healthcare finance executive with a passion for automobiles. When I lived in Alabama, I owned a car dealership that specialized in Mercedes, Volvo and BMW. We also sold many low-mileage ultra-clean Corvettes.

The dealership also sought the unusual vehicles and had a loyal following. Moving to Florida, I sold the dealership in 2018. However, my passion for vehicles continues.'

Sounds like a used car lot. And a recent one.

AND, a member since 2018 and NEVER contributed a dime towards this forum.

Self anointed 'experts' ? Make up your own minds on their veracity.

There may be some mistakes in any of our posts, not to defend anyone, but the his advice about how to check the steering issue here for the ram type p/s is correct. Done it this way in my shop, when I had the self steering issue on a 55 I was working on. Just sayin.

I am going to respond to each of these in the order given.

1.) I did not know that wood decking in a 55-57 wagon was part of the factory construction. Thus, I indicated same. If everyone knows everything, there is no point of the forum.

2.) The 70 Monte Carlo discussion was about a special "research" vehicle. My point was that these vehicles exist and many times they are not as special as thought. Mentioning the catalytic converter was in reference to 75 and later GM gasoline cars that were actually installed. And, yes, I did research and taught an evening class regarding emissions and catalytic converter function.

3.) My comments regarding the centerline suggested measuring the total distance to find the centerline rather than rely upon any factory stampings due to the age of the frame. If measuring and finding a centerline has become obsolete, let the rest of the world know.


I would encourage everyone to be considerate of others' viewpoints.

Also, with regard to "never contributed a dime", neither have most other members. There is no requirement that you be a contributor.

Wishing everyone a safe, happy and prosperous New Year.

The issue may not be related to the recent work, just coincidental.

First, as others stated, check the hose connections to make sure you have them plumbed correctly. This is the way it should be done:
On the OEM pump (on the generator), the LARGE fitting is the return, so on a late model pump, the return hose attaches to a CLAMP-ON NIPPLE, which is just a bare hose with no crimped fitting. The other end of this hose will be connected to the LARGE fitting on the control valve on the linkage.

IF THE HOSES ARE CONNECTED PROPERLY, then look at the control valve on the linkage. THE FOLLOWING INFO PERTAINS TO THE OEM VALVE, NOT THE REPLACMENT VALVE. The small cap on the end has a 7/16 nut under it. Remove the cap with a screwdriver and make sure this nut is snug. OEM nut has a clip holding the nut BUT some rebuilders use a nylon locknut, which can become loose over time, causing the symptom you describe. THIS NUT DOES NOT ADJUST ANYTHING! It must be snug but not too tight. (HOW TO TELL IF THE VALVE IS OEM OR A REPLACEMENT? On the OEM valve, the short hoses from the cylinder have short straight fittings on each end, and the hoses connect to the PASSENGER SIDE of the valve. On the replacement valve, these short hoses will have large radius piping on the valve end, which bend around to connect to the valve on the DRIVER SIDE of the valve.) ON THE REPLACEMENT VALVE, THIS NUT DOES ADJUST (OR BALANCE) THE VALVE.
