front end making chattering noise

[caddyhack]

so i just got a 94 4runner IFS 4x4 and from about 25-50 mph it is making a chattering / grinding noise from the front end. I serviced front and rear diffs with a synthetic blend gear oil, and also cleaned and repacked both front wheel bearing and seals is there anything else i should check?

This should really be in the Classic T4Rs section, but I'll try to help anyways. Could be diff bearings.

IM NEW!!! haha sorry this is my first toyota andd dont know all the gens yet but thanks for the info..
anyone else have anything??? also its comming from both front wheels

 

[rdgt4r]

could be bad gears, spider gear all those kinds of components in the front diff.

that could be it but it sounds like it comming further out near the wheels but i could be wrong i havent had anyone daring enough to sit under the truck while i drive 50mph haha :roadkill:

does anyone else have any other ideas? it sounds like a bearing noise but both rotor bearing are in good conditon no hot spots etc. and i cleaned and repacked both front rotor bearings and still same noise ???
