Wesley Posted May 11, 2014 Report Share Posted May 11, 2014 Our '08 Edge FWD Limited, has a knock in the front suspension. It feels like a stabilizer bushing but they look and and feel ok. It ONLY happens when either the left or right wheel hits a bump or pothole. When I go over a speed bump with BOTH wheels, there is no knock, so the noise is associated with individual wheel movement. I suspected it may be a spring seat but that would make a noise at depression with a wheel movement, left, right, or both wheels. Back to the stabilizer bar bushings. I got under the Edge the other day and tried taking the bolts loose. Tried is the optimum word. No luck. I broke one ratchet wrench and socket (Snapon, if it makes any difference). Interestingly, I cant find these bushings anywhere at any of our local auto parts stores and the Ford dealer says they dont stock them(!). I'm tempted to get a set of 33mm performance bushings and get out my trusty 1/2" breaker and 15mm socket and have at it! Ideas? Quote Link to comment Share on other sites More sharing options...
macbwt Posted May 22, 2014 Report Share Posted May 22, 2014 Strut bearing mount is bad. Time for new struts and mounts. Quote Link to comment Share on other sites More sharing options...
Wesley Posted October 31, 2014 Author Report Share Posted October 31, 2014 I finally got too frustrated and went ahead with the struts and mounting plates. KYB struts and MOOG bearing plates from Rockauto.com and about 4 hours of my time and the problem is gone. Not to mention that it rides better too, not that it was bad to begin with. Now all I have to fix is a hard transmission shift at very low speeds and load, like when driving around a corner from a stoplight. It bangs into second gear instead of a controlled shift. Increasing the load cures the hard shift. Different thread this time. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted October 31, 2014 Report Share Posted October 31, 2014 Isn't there a TSB for that? harsh bump at low speed starting from a stop, etc.? Quote Link to comment Share on other sites More sharing options...
Wesley Posted October 31, 2014 Author Report Share Posted October 31, 2014 The local dealership didnt acknowledge any TSB when asked. This is the standard answer I get even when I know there are others with previous vehicles we've taken in. When I bring in the TSB number, they say it only applies to certain vehicles and act surprised when I confirm that ours was included (three previous Explorers, one Lincoln Town Car and one Lincoln MKZ). As for if this vehicle is included in a TSB, I havent pursued it and it doesnt happen all the time. My Edge has 120,000 troublefree miles on it and I would be surprised if I get a TSB notice.

WWWPerfA_ZN0W Posted October 31, 2014 Report Share Posted October 31, 2014 I think the TSB was for 2009 & up? TSB 11-12-10 TSB 11-12-10 6F50-6F55 TRANSMISSION—SLUGGISH ACCELERATION FROM 0-8 KMH (0-5 MPH) FOLLOWED BY A HARSH BUMP OR A SLIP ON TAKE-OFF FOLLOWED BY A BUMP—BUILT ON OR BEFORE 4-15-2011.pdf Quote Link to comment Share on other sites More sharing options...
Wesley Posted January 11, 2015 Author Report Share Posted January 11, 2015 For what its worth, when I changed air filters this past week, I found that the duct hose connecting the air filter to the intake manifold was loose. The Edge has had a hard to pin down vibration felt through the throttle pedal along with the harsh shift. I dont know how it was loose but its been that way for quite a while. Tightening the hose clamp seems to have solved the vibration and as a side benefit it seems like the trans shift problem has gone away too. The mass air flow sensor is tied into everything it seems. 1 Quote Link to comment Share on other sites More sharing options...
PaulSchott Posted January 13, 2015 Report Share Posted January 13, 2015 If your leak is between the MAF and the intake, it will effect the readings and bugger up your fuel air mixture and I guess a bunch of other things too. Quote Link to comment Share on other sites More sharing options...
Wesley Posted January 13, 2015 Author Report Share Posted January 13, 2015 Thats the guess I had too. No harsh shifting since I tightened the duct plus the strange droning vibration is gone too. It felt like a motor mount was gone. Quote Link to comment Share on other sites More sharing options...
