Haven't even made a single payment on it yet. I went to a buddies house and did the vent mod for our rear diff, on his 2011 pro-4x and my SV 2017. I left his house happy and everything was great. I was pulling into my parents area and there is a little side street that's unpaved, not off roading or anything and this stupid god damn branch/stick was on the ground, I didn't see it but I felt it when it some how wedged itself under the truck. I went about another 5 feet before I finally stopped and got out to look, I saw this damn thing under the car near the passenger front wedged a little by the passenger control arm. I pulled it some and got it free, thinking I was ok the second I started to drive I heard a hallow sound, this is very hard to explain so I'm going to just list everything it has done since this stupid stick.





Rough Idle, i had a glass of water in the truck and it did the jurassic park thing where the water was dancing all over the place.
Hallow loud sound when I give it gas almost like an exhaust leak yet you don't hear it outside of the car at all, only in the cab.
Ticking/clicking/rubbing noise when I let go off the brake either in D or R, only for about a second then goes away.


I went under the truck the best I could at dusk and looked everywhere, I see nothing, I see no damage, I see no stick debris.

I'm honestly sick to my stomach over this. For the life of me WTF could it be, did this stick somehow break a motor mount? then whats the hallow exhaust leak sound, did I maybe break the header off the manifold ? or at least crack it,dent it or something.

I'm obviously going to look tomorrow better, maybe jack it up and really get under there, but not even sure how to proceed, if its damage I should see it. I drove it home about another 20 miles and it does drive fine, center steering wheel, no vibration while driving just sometimes at idle although it might have gone away. tested 4wd and 4low and both engage and work fine.


Dealer will probably rape me if its damage and cost me thousands.

Merry Christmas to me! :frown:

Understand I saw beating the stock front radiator plate was taking it was beatup the others had dents&scratches too an fuel tank was scratched up so I brought hefty's figured it was cheap ins. compared to replacing a hard part lol. But that $u(ks fastfed look at this way though could've been lot worse puncturing oil pan or trans skid would help there but not where yours wedged in it could've bent or ripped out your cv axle count yourself lucky things happen like me right after getting new tires less than 5k I was offroad an had ran something over that put a huge hole though 1 tire just had to eat it no road hazard on that set luckily I had brought 5.

Wishful thinking but maybe he'll have a Christmas or New years sale. Someone was trying to set up a groupbuy a while back but went nowhere maybe time to try again I don't really need but like and could find use for a set of sliders lol

Not sure what your deductible is but the damage may/should be covered under comprehensive coverage.

Rough idle. Maybe a sensor or sensor wire got damaged.

Have the truck up right now, looked for over an hour I cannot find a single thing damaged or even any signs of something wrong.
Gonna clean everything up there take the diff mod off and take it to the dealer Tuesday. See what they say. really sucks

You shouldn't need to take the diff breather vent mod off. I have all sorts of mods on my truck including that and have still had the dealer cover warranty items. Doesn't have anything to do with a branch hitting the front of your car, and they would have to prove that putting a better venting system onto your rear diff caused something.

Did it hit the fan or radiator or something? Or hit the belt pulleys? That's interesting that it is causing such a myriad of issues.

It's a damn Christmas miracle !!! Cannot tell you how happy I am right now.

I just spent the last 45 minutes under my truck with a brush and soapy water, scrubbing all evidence of dirt/mud. Soaked and dirty, I asked my dad to get into the truck and put it in D and R

AS he was doing it he was able to lock in the noise, I jumped under the truck and tried to trace it, I kept looking towards the front because that's where you hear it mostly.

As I'm looking I'm grabbing the exhaust and pushing and pulling it until one point the noise changed.

I cannot believe it but the problem was the damn heat shield around the mid cat between the doors. I looked closer and the shield bent and was pushed up against the cat housing. This caused the entire issue, the sound, the vibration and the noise. The heat shield is connected to the frame/body and the slight vibration from the exhaust caused the issue.

I took a pair of simple pliers and bent it back into position!!! Holy smokes!! Christmas miracle!! my brand new baby is purring like a kitten.

I'm now scared of dirt .Actually gonna buy some skid plates, but not sure skid plates protect that area?

Awesome! Glad you figured out the issue and it's nothing serious. That is always a huge relief when things turn out that way.
Merry Christmas!

I'm not entirely surprised that a component intended as a shield would cause problems.

Had a blowout with a Dodge D-series one ton truck many years ago, the tread/belts wrapped around everything on the suspension right there. Had a horrible sound for the rest of the drive home, found the backing shield on the disc brake had bent in and was dragging on the rotor.

Glad you found it. I'm planning on getting some used Pro4x skidplates for my SV from a junkyard over the next few weeks if I can find them cheaply enough.

yep, going to make a mission (if I except it) to find Pro-4x skid plates. I know they aren't all that great to begin with, but remember, I live in S.Florida. Our off roading is soupy sand or mud and thats it. No rocks , no mountains . Pro-4x skid plates are better than nothing.

Don't think the plates would have covered that area though

You've already got the radiator splash plate, you can easily find the other two motor and trans splash plates on eBay brand new for 50 to 60 dollars total. They take all of 5 minutes to install with 8 mm bolts. The splash plate for the fuel tank is ungodly expensive at 300 plus dollars. To which there is a member here who made a slider plate for the gas tank out of a sheet of 1/2" thick UHMW plastic sheeting...
