whirring noise

have a whirring noise in the front end (92 power ram 4x4)that is at the same speed as the turning of the wheels?
Meaning it occures once on every revoloution.

How many miles?

I'd try turning the engine off on an incline, and coasting downhill to hear better where the noise is coming from. It could be as simple as some brush wound around the axle, or as bad as bearings. Try to isolate the sound. With more info might be more help.

151ks ya i'll try and see if i can isolate it a bit thanks

Does the drive shaft from the transfer case to the front axle stay engaged to the front axle all the time?Sounds like the noise is in that area.

The front drive shaft, or the axle itself? I think on that year the front hubs have a vacuum disconnect so that they freewheel when 2wd isn't engaged. Might be time to jack up the whole thing and spin tires slowly to see what's making the noise.
