I have a 98 f150 off road 4x4 i can put it in 4x4 and the front is NOT spinning this its a manual trick with the 4x4 shifter on the floor any good checks i can go thru?

 

I presume you are talking about the front drive shaft not turning. Check your shifter linkage at the tcase to see if any thing is disconnected. If everything looks good then your problem is in your TCase.

If you are talking about the frt tires not spinning (like on ice) Do you have manual frt hubs and are they engaging?
