2000 Freightliner Century Power steering intermittent

Have not herd from the shop. They are short handed and may be a while. Will post the outcome when I pick up the truck.

 

Well, picked up my truck from the shop. It ended up being the slip joint steering shaft from the steering wheel down to the box. when the cab ride air bags fully inflated the steering shaft was stuck and was not extending like it should , therefore binding up the steering . There is no provision to grease this moving part. The shop indicated that they have seen this happen before. I ended up replacing the shaft with a new unit and will refurbish the old shaft and save it .. That was my problem all along. The bill for this was $1495.00. Would have never thought about the steering shaft and cab ride air bags .
