This may be impossible to do via video but I figure it's worth a shot.
I've got an 85 460 (F350) that's making a rhythmic noise up front.
I am planning on replacing the power steering pump as it's been leaking ever since I got the truck (2 months ago) but wasn't sure if this noise was that or the water pump.

Like I said, may not be possible for anyone to identify without being in front of the truck but it's that whooshing/whirring noise that loops.


Appreciate any ideas.

 

A stethoscope can help to pinpoint the noise. It does sound like a bearing.

 

I don't have one of those handy but would a pipe accomplish the same thing?

So my plan of attack is to first replaced what power steering pump, hose, and belts.
Then if I still have the noise I'll replace the water pump and fan clutch.

Is there a chance that a noise like that could be inside the engine? The short block was rebuilt about 2000 miles ago.

 

Pull the belts off and start it up..... see if the noise goes away.

 

A stethoscope is $3.99 at Harbor Freight. I would find where the noise is coming from, before you start replacing parts. Good luck.

 

Yeah, I'll pick one of those up the next time I get to the nearest town with a HF.
I pulled the belts off the p/s and waterpump and the noise went away. I really think it's the waterpump but I'll go ahead and replace the p/s first since I already have it on order, hook it up and see if the noise is still there.
Thanks

 

With the belts off you should be able to spin the pulleys and feel/hear the bad ones.

 

Thanks. Replaced the PS pump, high pressure hose, and all 3 belts. I am still keeping an eye on it but it appears that it took care of it. Also picked up a HF stethoscope for next time.
