Gibbs Garage Posted March 13, 2021 Report Share Posted March 13, 2021 2017 Platinum Edge 51K miles. No accidents registered on the car. There is significant tire wear on inner shoulder of all tires. After new tires have been installed, I have been working with the local dealer to correct the problem as I do not have a $$$ Hunter alignment set up. We found that the toe was off slightly on both front (current is 0.20 frt/0.10 rear). Rear chamber is at maximum allowed on the drivers front and rear (-0.7 front / -1.2 rear) the passenger side front is okay but the passenger side rear is at maximum (-0.6 frt/-1.1 rear) After the second try on the alignment machine they let me know that there is no further positive adjustment on either front struts or rear chamber eccentrics. Has anyone faced this issue? If so. how was it corrected.? Also, just to make sure I am working with the correct alignment specs... can anyone provide alignment specs for a 2017 Edge? I can provide before and after alignment readings if needed. Thanks! Quote Link to comment Share on other sites More sharing options...
ben senise Posted March 14, 2021 Report Share Posted March 14, 2021 too much camber is not necessarily the cause of inside edge wear. the problem is actually toe out when driving which can happen when you have either a bad alignment or worn parts that allow the tires to go toe-out when driving. the natural tendency of wheels is to spread open at speed. you may have a static -0.6 frt/-1.1 rear but when driving it will always be greater. if this were my car, that's where i'd look.

Gibbs Garage Posted March 14, 2021 Author Report Share Posted March 14, 2021 Ben, Thanks for the reply. I should have mentioned the toe was not out enough to cause the inner shoulder wear. The guys at the Ford shop "tweaked" it anyway while the car was on the rack. They agree with me that the chamber is what needs to be adjusted... but since the car is already at max. positive chamber they are at a loss. This week I will ask them to reach out to their contact at Ford for options. Quote Link to comment Share on other sites More sharing options...
David Young Posted March 15, 2021 Report Share Posted March 15, 2021 If you have not lowered (springs) your Edge, it looks like to me something is bent. You buy your Edge used? If so, I bet it has been in a wreck or hit a very hard pothole I lowered my Mustang only an inch and had to buy adjustable Camber bolts to get it right. Just wondering ............ 1 Quote Link to comment Share on other sites More sharing options...

Gibbs Garage Posted March 15, 2021 Author Report Share Posted March 15, 2021 David, Appreciate the reply. The car has a single owner since new. It is completely stock... no damage or modifications. Ford dealer I am working with indicates the camber adjustment is hard up against the max. positive adjustment so adjustable eccentrics / strut camber plates will not work to take away the max. negative camber. They are currently working with the guys on the Ford hotline to figure out what to do next. Still wondering if anyone has run into this situation... Thanks 1 Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted March 16, 2021 Report Share Posted March 16, 2021 I probably already know the answer, but have you maintained proper tire pressure? Carry heavy loads in the cargo area? Springs equal height? All bushings good? What type, brand tires? (Doesn't affect, just curious). Quote Link to comment Share on other sites More sharing options...
Gibbs Garage Posted March 16, 2021 Author Report Share Posted March 16, 2021 Appreciate the interest in this issue. All good questions... and, all of those items have been thoroughly "interrogated" by the Service Manager at the Ford Store. He needed all of that info prior to calling the Ford Hotline to discuss options to correct the camber issue. I am beginning to believe this car may be a "one off" since the camber is hard up against the positive adjustment with max negative camber existing. Just my suspicious nature... ?

1004ron Posted yesterday at 01:05 AM Report Share Posted yesterday at 01:05 AM Reviving an old thread because the description is similar to what I've noticed on my 2017 Sport. I haven't rotated tires for quite some time and this past weekend I notice wear in the inboard edge of both front tires - other than that all four are wearing very evenly. See photos of the right front wheel. What's your thoughts on the cause? Also, where can I find the alignment spec for my 2017 Sport? Also, my work colleague races his Corvette and just sold his string alignment kit and bought the Gyraline Alignment kit which he says he's very happy with - any first hand experience here? 1 1 Quote Link to comment Share on other sites More sharing options...

I am sure @Haz will chime in with the correct specs for 2017 (and maybe 2016?), I only have for the 2015, attached. As far as I know, 2015-2018 should be the same, but there always could be differences. Suspension Specs.pdf 2 Quote Link to comment Share on other sites More sharing options...

Haz Posted yesterday at 03:59 PM Report Share Posted yesterday at 03:59 PM Somewhat ironically, the Suspension System Specifications page is identical in both the 2017 Edge and 2016 Edge Workshop Manuals, with each bearing the 2016 model year Edge reference in its upper right corner, as shown on the below-attached PDF page...

See photos of the right front wheel. What's your thoughts on the cause? How's your ball joints? Other thoughts include control arm bushings & driving on low tire pressure. And as you mentioned, rotate your tires more often. 2 Quote Link to comment Share on other sites More sharing options...
1004ron Posted 8 hours ago Report Share Posted 8 hours ago "measure from the center of the wheel (hub) to the center of the fender opening. " Where do you measure the ride height? The above is what I've always used but the values listed in the document attached aren't anywhere near this.

1004ron Posted 7 hours ago Report Share Posted 7 hours ago Thanks for that @Haz My first thoughts were excessive toe in caused the inside edge wear, but the Ford doc states inside edge wear is caused by toe out. Reading Tire Wear Patterns Quote A feather edge on the inside of the tread bar indicates excess toe-in, while a feather edge on the outside of the tread bar indicates toe-out. 1 2 Quote Link to comment Share on other sites More sharing options...
garycrist Posted 6 hours ago Report Share Posted 6 hours ago (edited) What brand of tires and what is the DOT code on the tire? It appears so one likes to drive what some would consider a little "sporty". The shoulder wear (both sides) indicates where the steel belt ends. If it was a toe problem, the edges of all of the tread blocks would have a feathered edge on one side. But, the pics indicate small chunks are being shed while at high steering angles. In the top image it appears that a little extra wear is indicated by the right side being a little more worn than the left. That would indicate about half a degree of extra camber to that side, providing that is about 12 K miles in normal conditions on that tire.
