Question 96 F-250 Grinding sound?

Hi im hoping someone can point me in the right direction. I have a 96 F-250 with a diesel engine and automatic. It has 250,000 miles I just bought it 3 months ago. I hear a grinding noise and I feel vibration on the acceleration pedal. It seems more pronounced when steering slightly to the right. It only seems to do this when I am accelerating. A neighbor said that it sounded like I was in low gear. But I was only in drive, how can I tell if it is in a low gear? And does low gear only happen in 4x4? Im so afraid I made a mistake buying this truck. I really love this truck because it sits up high and I love hearing the diesel motor and I can get around in the snow . I have read different things on forums, some people talk about the locking wheels being stuck, how can I tell if one of mine is stuck? Or a U-joint? Thankyou, this is my first Diesel truck.

You got a good model truck so relax. It is 20 years old and will have some problems but they can be repaired. Could be a few things making a grinding noise. Check out if your truck is attempting to go into 4WD as you drive down the road in 2WD. A loss of vacuum to the hubs will cause the hubs to grind. If the vacuum to the front hubs is intermittent or moisture in the lines. Now you will ask how do I check all this out? The answers are here in the forum search topics.

There are no vacuum hubs on any OBS.

There could be many different things grinding. You need to pin point it better.

Does it have manual or auto hubs?

Does it do in in 4x4 or just 2wd?

Start with the front wheels and check the hubs for operation, brakes for any issues, wheel bearings. The old auto hubs can grind b/c of old, thick, cold grease or too much grease hanging things up in the hub.
