I think Ford is well aware of the overheating issues. They are just not doing anything about it for US customers.

I found a TSB that referenced AWD Edges in the Middle East. Any Edge with less than 100,000 got a free PTU replacement that had a drain plug. Of course the p/n for that PTU is not available in the USA.

your statement to get our s**t together is pretty ignorant. Ford does not provide a way to drain the fluid. The PTU is not a serviceable unit. If you take it to the dealer and ask for a fluid change they will refuse and inform you it is lubed for life.

This is a well documented issue. I even found a TSB that Ford offers a PTU replacement unit with a drain and a 100,000 mile extended warranty for the Middle East. While that has not been extended to the States is beyond me.

It is my understanding that you can just use a lithium grease. It can be purchased in a spray can. If you need to clean out the old stuff a little mineral spirits or brake clean on a rag should do the trick.

The sunroom is designed to stop about 6 inches short. That's the vent position. To close you have to press and hold the button. Annoying, but that's the way it is.

Per a thread that a user called thenatrix participated in he disassembled a unit and was able to replace bearings. As far as labor is concerned I will be performing all labor so other than my personal time, labor costs are not a concern.

Sorry to revive an old thread, but please can anyone give me any details about a lawsuit pertaining to the PTU?

So with problems surfacing at only 62,000 miles it has been determined that the PTU on my 2008 Edge Limited AWD has overheated and needs to be replaced. I'm not going to go into the backstory in this thread. If you want the complete story I guess PM me or I can post it up if there is enough interest....

Since I cannot afford to have the dealer replace the PTU at a cost of $1500 I have decided I have 3 options. My hope is that there are others here that have perhaps gone one of the routes I will outline and can give me some feed back on their experience.

1: Drill and tap a drain plug and do regular fluid changes. My hope here is that there is no internal damage done. Reading other threads here it seems the preferred method is to drill and tap a 1/4" pipe thread. Flush the case with kerosene, flush with motor oil, flush with gear oil then flush monthly a few times until the gear oil is relatively clean then have an annual fluid change.

My question is, when you fill the case with kerosene do you drive it at all to get the fluid in all the nooks and crannies and try and knock the gunk out? I know not to drive it that way and extended period, I'm thinking a few hundred feet. Same with the motor oil flush. And to those that have done this what is your success rate? Are you still driving with this PTU unit or did you eventually have to replace?

2. Remove and disassemble the PTU, get it all cleaned out, replace anything that's bad and reinstall. This is a very attractive option to me as it would give me piece of mind that everything is ok internally and if it isn't it would be repaired. The only problem here is if there is anything bad and I need to order parts or I decide I have to go full replacement anyways I'm down a car until the parts come in. Due to my wife's and my schedules overlapping driving each other around with one car isn't an option.

3. Total replacement of the PTU. This is the most expensive option, but it just gets the job done.

If anyone has done option 2 or 3 I'm looking for difficulty level. Tips and trick and anything I need to look out for. Also if someone had a Chiltons or Ford manual and would be so kind as to scan and e-mail me the appropriate pages you would be my hero.

Also looking for tips to prevent the overheating. It seem to be the general idea that the routing of the exhaust may be the issue as the catalytic converter is right next to the unit as well as the main pipes coming from the engine. Heat shielding may be the best bet to prevent future issues. Anyone with pictures of DIY heat shielding around the PTU would be appreciated.

I bought our 2008 edge limited with Nav used. It did not have the Nav instruction book. Is there a way to purposely turn off the warning screen that comes up when you turn on the car? It's annoying to have to hit accept everytime you turn it on.

Thanks

If you feel you have reached a dead-end with your dealer, maybe Todd or Tricia of Ford Customer Service can help. There may be a possibility that PTU fluid replacement could keep it going for some time, but we don't know why it is leaking. Is it the PTU overheating, or is it transmission fluid leaking into the PTU then being vented?

 

What color was the leak? Brownish or reddish? If clearly brown, it is likely PTU fluid, if red, transmission fluid.

I have already been in contact with Todd. But thanks for the suggestion.

The fluid is black, thick and sticky. Defiantly gear oil. It's definatly blowing out the vent. I'm not sure it's exactly overheating but I can't offer a better reason. After some searching here it's not that uncommon for this to happen it seems.

I guess we will see how it all plays out. If Ford in unable to offer any relieve I will probably replace the PTU myself. I can't afford $800 in labor.

All they did was take it for a test drive. Since they could not replicate the problem they did nothing further.

As for the leak the deal was replaced at 61,000 miles. Now at 76,000 they claim it overheated and is leaking from the case and the entire unit needs to be replaced. Ford covered the leak under goodwill the first time. They wouldn't even ask ford for assistance this time.

Considering it started leaking immediately after the seal replacement I feel they screwed up something. I am not pleased at the moment.

I had hoped to have a resolution to this. I had to bring it in for a PTU leak. They claimed there were tests that can be done. All they did was drive it around.

So I'm no farther than where I was this morning. *sigh*

bought it used in 2011. The dealer replaced the battery before we bought it from them

If anyone could be so kind as to post the p/n for this I would greatly appreciate it. I would assume it would fit the 2008 as well?

Thanks

nope, no CEL and no code.

I have a 2008 Edge Limited AWD. I'm having a problem with the transmission. When I shift from park into gear it will not go. press the gas and the engine revs up. It will move a little but not more than a walking pace. Only way to correct it is to turn the car off and then on again. Sometimes this needs to be done several times.

This is very, very intermittent so it's not something I can take to the shop. It will go for months without issue. I'm sure it's just a sensor or solenoid but not sure what? Anyone have a similar issue and found the solution?

Thanks, you rock.

This looks like a super simple job. I'll try and get some photos. I should have the shaft in a few days but due to my schedule probably will not be able to work on it for a few weeks. Hopefully my shaft dosn't implode before then.

Here is an excerpt from the manual.

 

Instructions say to break the control arm from hub assembly at the ball joint. If you can do it at the control arm and leave the ball joint intact, seems even better!

 

Have fun.

Thanks for the scan. It says to refer to the "procedure" for the hub nut torque values. Would you be able to scan that part as well? I would really appreciate it.

I was going to go with the lower control arm only because I found a How-To for a CV replacment on a Ford Escape. I figured it would be similar on the Edge. Once I get in there I'll take apart whatever is appropriate.

Does anyone own a repair manual? I need to replace the drivers side CV shaft and would like to know some torque specs.

Looking for:

axle nut

steering arm nut

lower control arm nut

Thanks!
