Weird hydraulic swoosh sound

[machattack]

Hi everyone.
Ive asked a couple members for there thoughts on this problem and Ive followed up with there suggestions. I still have the problem and was wondering if anyone else had a suggestion?

I installed a wood steering wheel and I believe after doing so, I get a swoosh sound transmitting up the steering column radiating the sound into the cab. When I turn the wheel left or right about half its travel distance before the steering stop.
The sound is defiantly the swoosh of hydraulic fluid from the power steering.
I installed a new rebuilt redhead gear box O.E, a rebuilt O.E power steering pump. and New belt. Pump is full when hot. No leaks. The assembly has about 2k miles on it now and never a swoosh sound with the O.E wheel before I installed the new steering wheel.
I loosened the steering nut and re-torqued it to 35 pounds with Loctite. Is that steering wheel nut suppose to have a nylon flat washer? or a steel lock washer?

Stupid noise is driving me nuts every time I drive the car.
Any suggestions? I appreciate . Thanks for your help!

If the PS system was not making a weird noise before, then I would have to think it's the new wheel rubbing on something at the column.
It's either that or a total coincidence that the pump is now making a noise. Could be some air in the system somehow or the pump starting to go bad.
Make sure the new s wheel is good first and go from there.
Annoying for sure, good luck.

I had on on my car for awhile. I bet it’s what Stanglover said. The hub on the back of the steering wheel is rubbing on the column. Mine did the same, had to sand it down. I finally restored my original wheel, which I like much better anyway.

Is there suppose to be a lock washer or flat nylon washer that goes on the steering wheel column nut?
Ive applied tool maker dye to the wheel hub and column attachment. I'll run it a few days and see if it leaves a witness mark from any rubbing.

No lock washer, the nut should be self locking. Not really sure the exact name for it.
I could see where it was rubbing by just turning the wheel back and forth.

Anybody know the size and thread on that nut? mine isnt self locking for sure.
Jpaz, I couldn't see any spots where it was rubbing. Thats why I applied the tool maker dye to leave a witness mark.

I don't have the size and pitch, but they are called "distorted thread lock nuts".

Thanks for the info!
The nut size is 5/8th x 18 fine.
