Title: Power Steering failure
Post by: Egoboost on April 27, 2016, 10:16:59 PM
Hi guys,

Reaching out to see if anyone here has experienced/gone through the power steering recall and what symptoms they experienced/felt in the steering.  From what I gather from reading up on it, the issue can either throw a code or not, and the dealer will either replace the steering gear or update the PSCM depending how they diagnose the cause.

This is what I'm experiencing: intermittent power steering loss at various speeds, turning angles, rate of how slow or fast I turn the wheel...in short random kicking in & out of assist making the car...ahem...unpredictable in terms of steering effort.  I can come to a stop, make a 90-degree turn with my fingers sometimes, other times it takes both hands...and sometimes I'll regain or lose it in the middle of that turn which pretty much makes me look like a drunk.  Same goes true for something as simple as a lane change.  And all of this out of the blue... it just started on Monday and has been this way ever since.

My thinking so far is this: ball joints are fine so likely no binding there.  No noise whatsoever when turning the wheel and car still tracks fine, no slop, so not thinking rack.  Strut mounts seem ok, so will eliminate that as well.

Which leads me to my problem...I'm thinking this might be a result of the recall issue...BUT my car is a '10, which is not stated in the recall...only 2011 forward.  So, what do you think the odds are of me jumping onto this recall?  Am I barking up the wrong tree and it's something completely different?  Any help/advice is greatly appreciated.

I think if you get a good dealership, you should be able to get your car serviced under the recalls/TSBs.  Sometimes Ford expands the MYs included later on, sometimes not.  Not a hard-and-fast rule, but meant to be a guideline.  Sounds like the EPAS gear to me though.

Thanks, guys...I'll try my luck with the local dealership and see how that goes.  I'm working under the assumption that the steering componentry is the same as the 11's & up and hopefully they'll be nice to me  ;D.  A box of donuts can't hurt either.

I was curious to know whats the Build date on your SHO ? Based on this file it affects 08/10 up models.  Z

Z, thank you so much for that info.  My build date was Dec '10, so I should be good to go.  Makes me feel a whole lot better knowing that this is very likely the issue causing my problems.

Appreciate the help for sure, can't say enough about what a resource this forum is to all EB platforms.

But no good deed goes unpunished and after a few phone calls it turns out the recall is VIN-specific and mine registers as everything hunky dory.  So a trip to the dealer this week and an update on my financial ruin later on.

Dealers can sweet-talk Ford into "exceptions" if they want to.  So I wouldn't give up just yet.  Also keep all documentation and approach Ford/Lincoln directly if the dealership angle does not work out.  They might meet you part-way as a goodwill gesture, so be polite but firm ;)

So here's the update...turns out the u-joint in the lower steering shaft was gonzo.  Required new shaft + alignment.   Got it back today and a shop bill for $1000.  The dealership is trying to work on some goodwill with Ford, but I have my doubts since I'm a 1st time customer but what's the worst they can say.

Where they able to retrieve any of the DTC'S mentioned above from the PCM?  Z

Ouch!  Maybe some goodwill will come your way, that'd be nice ...  First mention of the U joint being the culprit ...  Wonder if it was this part in question:

The diagram doesn't show the knuckle, which is classified under Front Suspension/Suspension Components

Negative on the DTC's, even asked the tech if there were any stored in the PCM (I had no warnings in the dash display).  Said my issue wouldn't necessarily incite a DTC to be thrown since it was a mechanical issue and the steering angle sensor woud not detect an issue as there was no deflection in the position of the shaft.  Said he's never seen one of these go before.

SHOdded, you're correct on the culprit, in fact I think they showed me the exact same diagram!

Keeping my fingers crossed they can still get some goowill due to this being such an oddity.  At the very least, I established a relationship with the dealer, and they've been really good to me.  Even rushed the repair for me yesterday so I could get the car earlier.
