    Changed the oil in the tranny / rear end lately?
    I would check both and change if you don't know when it was done last.
    I found the vent cap was missing from my rear ends vent line and found the rear pumpkin had water in it when I drained it and refilled.It could be a bearing in the tranny.
    It's so hard to tell with out listening to it and riding in the vehicle.
    My brother had a 5 spd that made a grinding noise like that and it was a synchronizer assembly in 2nd gear that just made it hard to shift in to 2nd above 25mph.
    He drove it for 50k miles like that.
    How many miles is on it?

    Thanks rig1

    I changed the rear end fluid not to long ago when i did new axle bearings and seals.

    Im gonna check my vent right now.
    The trans fluid is not too old.
    I,m aware of synchros scatching in to gear. Usually starts in second then 3rd is next
