Hard Steering To The Left, Fine To The Right

[tobypineo]

This has every mechanic in town scratching their heads. My '04 Sierra 4x4 1500 turns hard (no assist) to the left, and perfectly to the right. Once in a while it is ok to the left too. But the right is always fine.

 

There isn't much of a consensus on what to do, hoping you guys can help.

 

Thank you for reading.

I once had a similar problem with an older truck when something broke in the steering damper.... it was like a shock absorber that once removed was very easy to extend, and almost impossible to compress, instead of the even resistance it should have in each direction.

 

I dont know what the mechanics who have looked at it actually checked for you, but there are number of possibilities. the only one I personally have experience with is the one I mentioned.

Is it rack and pinion steering? I've seen this very problem on bad steering racks on import cars... I would assume it would also be possible in a truck. Just a guess.

Did any of the shops perform a ps steering pressure & flow test? There is a test procedure to see what's going on. Find a shop that can perform this for you. It'll be either the ps pump, the ps pump flow control valve, or the ps steering gearbox-(most likely this is what's bad).
