Hey guys and gals. Im at my wits end with this damn noise. I have a 95 f350
PSD. I just had the e40d trans rebuilt and the day i got it back when I was almost home when it was good and warmed up it starts making this squeeling noise. like the noise a garden hose makes when you kink it just right. It will only make it when the truck is moving. forward or back doesnt matter. So far i have checked the brakes, all the inlet pipes and connection boots and clamps, tightened all exhaust connections including the manifold bolts st the heads. Replaced all 3 univ joints and the carry bearing on the drive shaft. even jacked up the rear end ran it in drive and could not duplicate the noise. the truck has to be moving. its hard to say exactly where its coming from but it sounds like its coming from under the cab or right at the fire wall????
My mech buddy thinks its a exhaust leak, but cant seem to locate it. could it be the down pipe got damaged and or punctured while the trans shop removed or installed the trans. Also read something about it maybe beeing the front trans pump.
I dont know what else to do. i think im going to change out the down pipe and see if it goes away.
any body got any ideas?
Any help or advise is greatly appreciated.
