Sensation of tires rubbing at full lock

[justinh]

When turning FULL lock and at slow speeds (like in/out of parking spots) it feels like my tries are rubbing (they aren’t).

This is a fairly new issue and I can’t seem to come up with anything other than I’ve recently used 4a and 4hi several times.

It doesn’t feel like the bucking of turning a 4x4 on asphalt. Just like tires rubbing.

Any thoughts?

What pressure you running?

35-37, but with as cold as it’s been the last few days it’s probably lower. However, not low enough to trip the TPMS or anything.

It could be the IWE system. Were you in 2 hi when this happened?
Also, was the vehicle up to operating temp, or still cold?

I seem to recall that the IWE system keeps the hubs engaged during cold operation up to a certain point, and then ‘disengages’.

Is the behavior the same in 2H as it is in 4A ?

First thing I would do is replace the IWE check valve...

That’s definitely an interesting thought given this cold snap. I don’t recall feeling it before but my wife and son drove my truck this weekend in the city with lots of low speed tight turns and called and asked “what’s wrong with your truck?” I drove it the next morning and figured out what they were referring to when at full lock.

I don’t know how people with cold weather live with these things. We have a 2007 and 2017 and both had the doors frozen this week. It’s amazing that ford doesn’t seem to fix this stuff across several generations of trucks.

Lower ball joints going bad? At slow speeds my tire was barely rubbing by the upper ball joint when the lowers were going out.

Are you referring to the door latch being frozen or the door itself? We had 2 degrees and snow here recently and there were plenty of people with doors frozen shut across all males and models. That’s not a design issue, it’s environmental.

I was going to say pretty much the same thing. EVERYBODY'S doors froze shut in a huge geographic area in the last week, no matter who made your vehicle. We went from 51 and raining to near zero in about 6 hours. That will freeze anything that's parked outside.

It was actually both initially. But once I was able to open the doors the first time that wasn’t an issue again, the latches stayed frozen on the back doors for nearly 3 days.
