DunePearlEdge Report post Posted February 25, 2016 Are these bolts left untightened correct? I have a lot of vibration. My 2007 Ford Edge was at the dealer today for a fuel tank replacement due to a recall. To replace it they have to unbolt the rear driveshaft. The car vibrated a lot (much more than usual) on the ride home. Is this normal? The bolts can be spun by finger. Share this post Link to post Share on other sites
CinnamonEdge Report post Posted February 25, 2016 OMG. That is not right! get that towed back and have them replace the seal now that the vibrations probably ruined it. the blue stuff is Loctite so that the bolts cant come loose. it should not be showing at all. 2 Share this post Link to post Share on other sites
DunePearlEdge Report post Posted February 25, 2016 Thanks CinnamonEdge. I tightened them myself and it helped a lot. If I show the dealer this picture I don't think they'll believe me - although I did notice the blue falling off the bolt as they were tightened so it's clear they weren't previously tightened in the picture.

WWWPerfA_ZN0W Report post Posted February 25, 2016 Is that shot from where the driveshaft connects to the RDU? Do you know if it was "oily" before? Hopefully it's just the techs being messy, but it could be the rear pinion seal is going also. Share this post Link to post Share on other sites

Hopefully it's just the techs being messy, but it could be the rear pinion seal is going also. That is the connection at the rear of the driveshaft below the fuel tank, is that the RDU or PTU? I don't remember that area being oily but I'm not 100% confident on that. Is there a way to check? Share this post Link to post Share on other sites
WWWPerfA_ZN0W Report post Posted February 25, 2016 That is the RDU. Wipe it down best you can, keep tabs on it for now. You might want to put it on record with the dealership also if you talk to them about the bolts, but at least you have timestamped pics as backup. Share this post Link to post Share on other sites
