C4 Help

[FordTruck]

Hey guys i just bought a new 70 F100 project/daily driver. Its a 302/C4 but every once and awhile it'll make a noise like a squeal with a slight grind it olny lasts maby a second and seems todo it when i gas it kinda hard while turning. I drove the truck home almost 80 miles and it olny did it twice once when iwas turning around or gassed it from a dead stop round a curve. The fluid looks fine,clean and is olny a drop or two at most low and the truck shifts out fine through every gear. Any help/ideas on whats goin on?

Doesn't sound like a transmission problem to me. I would look at your front wheel bearings first on the side which is outside on a turn.

I would check rear axle bearings, also.

Thanks guys I gotta do brakes so I'll check all that when I tear into it. It did it once again this morning I did a little showing off with my posi track in the driveway andmy drives a steep hill and it shifted outta first made the noise then went right into second and I drove the truck around and its still shifting a ok.

( a steep hill and it shifted outta first made the noise then went right into second and I drove the truck around and its still shifting a ok.)

Does this happen during the 1 / 2 shift ? Can you relate it to the shift into 2nd gear....Do the wheels have to be turned for this to happen ? Or does it happen on a straight drive away start? Wheels straight ahead?.......

Dry u-joints can also make a similar sound.

It seems to only happen when the wheels are turned to the right. I took it out on another drive this evening and I went out and it shifted manually 1,2,D no problem and I punched it on both flat and hills with no noise. Til I made the right turn and started climbing the hill it made the noise and got bout half way up and tapped the brakes to make a left into my parking spot no noise but the brakes got super squishie and the front chamber was bone dry...could this have something todo with the noise?

Bobbyford- The u-joints are on tomorrows check list cause I got a clunk when I drop it and gear.

I've never had anything like this with a C4, but my AOD I did from a swap does this. So It could be possible, but I would definitely check other things especially those ujoints and the diff. Possibly the power steering pump? I had one that sounded just like that.

Thanks for the replies guys....im also starting to think its not my trans ive had nothing but bad luck with autos in bumps so im a little paranoid about transmissions but ive been dealing with a week long brake ordeal so i aint done awhole lot tracking down the problem but i did notice the carrier bearings in bad shape so im gonna start with that and u joints
