2005 escape rear wheels lock up going down road !

Postby Brians2005 - November 17th, 2015, 7:58 pm

My 05 escape has locked up back tires 2 times now this time I went head on with guardrail ! What in the transfer case/ PTO unit would make this happen ? An how can I rewire it so I control when back wheels kick in ?

So the brakes are not locking the rear tires?
You are just driving along and the rear end locks up and skids you to a stop?
Does it make any catastrophic-sounding noise when this happens?
Is it one or both rear tires?

The drive shaft to the rear axle is always spinning, being driven from the PTU. The coupling at the front of the rear differential (in the pinion area) is the power application point. You can remove the rear drive shaft and run around on the FWD to help diagnose, but will trigger the '4WD' warning light on the dash, no harm done though.

And then what did you do? Did you back up and then continue your drive? How did you get them to release? How fast were you going?

You are giving us hardly any information. Describe the WHOLE event, not that my rear tires locked up.

I drove 45 minutes to work got sent home ( due to flew) 25 minutes in to the drive home ( a drive that I've drove hundreds of times in my 02 escape an a few hundred in this 05 escape ) started around a small corner in the road . no noise or anything just back tires locked up I skidded side ways ( lost control) went head on in to hard rail . when I hit hard rail I bounced back far enough that I was spun around facing other way ( never left drive ) when I gained my wits I moved out of road with no problems. Cops came wrote out report I drove car home I was doing 55 when back tires locked up . as of right now I'm still driving it . this is not first time its done it its the 3 time first two time I was doing under 30 mph hope I answered everything

I'm at a loss here.
I cannot think of a failure that would cause this unless there was a ton of noise along with it, such as a broken driveshaft that became lodged while it was flopping around underneath the center section, but it would be obvious that there was something wrong, like beating against the floor/ground/gas tank/exhaust as the vehicle moved.
It's possible that the rear differential has had an internal failure and a piece of something became lodged between the ring & pinion gears, and a slight movement in the opposite direction (moving the vehicle backward) allowed this foreign object to fall, which allowed forward movement again. But even here, I would expect gear tooth damage and noise/grinding/chattering to be noticeable. Pull the rear differential cover to drain and inspect the R&P and spiders for damage (chipping, sharp edges, missing teeth), and look for chunks of anything laying in the bottom.
In both cases, I'm surprised that the rear half-shafts survived this sudden wheel lock 3 times without the CVs breaking, if they are truely being shock loaded during this event.

I'm curious how do you know it's the rear? What you have more sounds like a transmission issue cause as boogie said, there's no clear explanation for why just the rears lock up.

Your traction control could be going off my newer escape does it a lot sometimes causing me to slightly lose control but my escape makes an audible,gear grinding sound then the brakes change the amount of torque the wheels are getting (applys the brakes to decrease wheel speed) mine usually goes off on a gravel. Road you could have wheel speed sensors going out. I would try finding a wide gravel road with a sharp corner and try to get a little sideways and see what happens
