Have a very stock 86 4x4 3/4 ton. It's had a grinding thing going on in the left front wheel on sharp left turns for a while now. It's progressing to sort of a whirring noise(like if I had big off road tires) while driving straight and around 25-40MPH, then goes away if I go faster. I have a hunch I've got a bad bearing and CV joint. Has anyone had this problem? I also noticed on the both front wheels the locking hub assemblies are loose, they come away from the wheel maybe an 1/8"-1/4" and even have a little lateral play. Could this be connected to the grinding, and am I in danger of loosing a hub assembly while driving down the road? Because that would stink! Thanks for any input

Not going to be a CV joint as these trucks don't have them.
Need to pull it apart, and identify the problem asap.
Shouldn't be driving it even with a little grinding noise let alone a few weeks with it getting worse. What might have been a simple fix now might be huge $s. The spindle could be damaged if it is in fact a wheel bearing going away and not repaired right off.
It is possible that the wheel hub assembly could come off. That would stink, especially if it took out a child riding his or her bike or something.
