Answer

Ok, this is almost always a bad sensor in the shifter on the side of the transfer case. HERE are instructions to replace that sensor. I would have the code from the transfer case module to confirm this code, which is C0327.

no these were 2nd or third set it has about 160thousand miles

Answer

OK, The only reason for the tires to wear like that is a bad alignment or the tires not being rotated. The upper ball joints would cause this, but any tech worth his/her salt always checks the front suspension when doing an alignment.

At 160 thousand they r probally due the have the alinement checked by some one else

Accepted Answer

The lower usually do not cause that much of an alignment issue.
