Intermediate Steering Shaft (ISS)

Easy and inexpensive fix. DIY. Do a search on this forum. All sorts of info.

Tighten the cross-member bolts in the front. If it's still there, replace the intermediate shaft also.

The I-shaft will be about $200 and tightening the cross-member bolts should be no more than $30-$50 in labor only. They should be able to take care of you.
