That's a good idea and very easy to try. The same concept could work if the harmonic is exciting a resonant frequency in the steering column by clamping a weight on the steering shaft. Works like a resonator in an exhaust system does to change the natural harmonic frequency of the system.

Yep, I'm gonna try something like this.

Well this is sure an interesting thread! I was planning on getting the Borgeson box so I am
watching this closely to see how this plays out..... that sound is very annoying and not something I could live with
With my restoration......

A "restoration" wouldn't have a non factory steering box in it.

Uh... ok...... how about “Restomod”? Are we good now? Now back to our thread....... I have noticed that some of the stock power steering hoses are Quite large in diameter and maybe this has a quieting or damping effect? I may run this issue by Amazon Hose and rubber here in Tampa and see if they know what the deal is....... TBF

Larger hose is usually the return, low pressure high volume.

WRONG!

This is just a personal opinion having attempted to deal with this... and ultimately failed!
I believe the hiss is caused by the design of the coupling.
Its metal to metal where it connects to the spline on the box
I don't believe the use of the setscrew helps this either.

If you don't buy this theory,
WIth the car idling in Neutral, put your stethoscope right on the end of the coupling past the set screw but not on the box...
You'll hear the same sound you hear in your passenger compartment just amplified...

This is just my opinion (I showed to several engineering friends of mine)
Their opinion was unanimous....
The coupler, while well meaning is a hack.

Yes, it "fits" but…. I personally feel it needs to be re-engineered to muffle out the sound where it connects to the spline
and it should use a roll pin just like factory....

WARNING: Don't buy his pump expecting it to fix anything.. it doesn't.
He's basically offering it as a try and see... (think about that for a second)
(in reality this entire setup is a try and see!)

If you switch to his pump pay very close attention to your mounting brackets..
If you have the 70-71 oval pump your brackets will NOT fit the newer style pump (although the look like they do!)
and everyone and his brother tells you they interchange....True, bolt holes all line up and as a result
the brackets bolt right up but watch the clearance on the front big bracket
to the housing of the pump...it will interfere when you tighten it completely down....

You will only discover this after you've removed your pump,
bought his, bolted it all together and then bam... you can't use it!

He may try to sell you a new bracket to mount your pump with....
Then you will discover (the hard way) two things

1) that the return outlet is larger than the stock outlet and in a different place.
So you will have to get a larger diameter return hose than your stock..
Hint: if you have a stock PS pump and return hose your stock clamps wont work either

2) The location of the return outlet is different on his pump vs your stock pump
so your return hose will not be in the same location
This will rear its ugly head only AFTER you bolt the new pump in and try to tighten the belt...

My recommendation... if it's hissing in your passenger compartment.
Remove everything, return it immediately, and get [ball][/b] of your money back.
Don't settle for this...

Again this is a personal opinion based on painful experience with this setup.
Rightly or wrongly this is NOT an engineered system for a MOPAR
It is a collection of parts that "fit"
It well meaning and well intentioned
and I deeply appreciate Mr. Bergman for attempting to address
what I think is absolutely the worst thing about old Mopars (the pinky power steering)

I give him further kudos as he did STAND behind his warranty
and did not hide behind it like so many other parts people do...

But... for the $$$$ I said forget it...
I say that with the utmost disappointment.. Because I personally wanted this to work BAD!!!!!
I did everything I could. ….

Hope this helps

I have a different setup, but for what it's worth, I just converted my '70 Challenger to a coilover front suspension with a power steering rack and a GM Type2 power steering pump. When steering back and forth in the garage my steering column had an annoying vibration along with that hissing sound. Turns out the pump was making slightly too much pressure for the Ford style rack.
I installed a power steering pressure regulator inline with the feed and return lines(the excess fluid goes right into the return line so no extra heat is added to the pump) and now my steering is silent and I can adjust the feel of the system to my liking around town and on the highway.
I have no idea if this will help you or not but it's a thought.

The regulator is Heidt's part number PS-101 and all my lines are 6an. I also ran the return line through a small fluid cooler. It was installed from the beginning, before the regulator was added.

Does anyone know if the hissing problem has been fixed? Just seen about these boxes but don't think I can handle the hissing sound.

Read the post directly above yours

We had the same problem after converting a Ford Falcon using the Borgesson kit. Steering was nice but the noise is loud! Borgesson admitted there was a problem and offered NO solution or refund. Basically told us too bad! They really don't care!

I hear and feel your frustration... I've been there.
But they do have a warranty and they stood behind it when I had my issues..(which are identical to yours)
You should remind them of that and ask nicely for a full refund...

I fought with Borgeson about my box as well for the hissing. I went back and forth they blamed Bergman's coupler for the noise as their coupler has some rubber/RTV in it that they claim solves this. Obviously Bergman autocraft called this B.S when I showed him the response I got.

In the end Bergman got Borgeson to take the box back for warranty. They "repaired" it but didn't detail as to what. I haven't been out with the car yet but from driveway tests it seems to be solved so far.

That’s a Saginaw pump. Early style with oval can.
