Dragging front lower under cover panel.

[mwalsh]

I don't know how unique this is, but my front under cover panel (under the motor) has busted out at the rear bolt. This was due to incorrect reassembly after I got my warranty replacement battery pack - instead of tucking the cover's trailing edge up into the chassis first, the technician simply bolted it into place. I knew after I saw it dangling the first time that this was how it had happened, and knew that it was incorrect because I had already taken this cover off once from it being factory new (when I installed my air horns).

The incorrect install caused stress on the cover material and eventually a circle the same size as the bolt washer busted out of it. As a result, more strain was put on the plastic push-rivet clips and, even with the cover trailing edge installed properly, without the added support of that one bolt and with a propensity for the cover to work itself loose again (probably by catching it on speed bumps and/or dips in the road), they have eventually all given up the ghost too.

A couple of times now I have noticed the cover has been dragging on the ground at low speeds and have improvised a repair. Having already tried zip ties and have them also fail, it is currently held in place by a bungee cord stretched between the chassis rails towards the rear of the cover. Totally ghetto, but it's been working for about a week.

Anyway, the point of this is that if anyone needs replacement rivets, the part number is 01553-05933 and I picked up a bag of 10 (nice to have some spares) on eBay for $13.50 shipped. About the best price I've seen with the shipping included.

If your under body cover gets absolutely trashed, the part number for a 2011 is 75892-3NA0A and it runs about $100 plus shipping.

Mine just looks a bit rough, so I plan on repairing it by reinforcing the busted out bolt hole using some of the metal strapping generally used for securing water heaters. I happen to have a rather large spool left over from a WH install, and it occasionally comes in useful for other things. I'll either epoxy this in place or bolt it on, making one of the holes in the strapping match the position for the bolt hole in the cover; then I'll paint the strapping black to match. I think the prospects for having this repair last a while are pretty good. Pictures to follow (maybe).

Thanks so much for posting this! It's 5 years later, but the information is valuable! The part number for the clips and the actual "splash guard" made it easy for me to figure out what this part is "Splash Guard" "Under Cover" "Under-body cover" ...

My wife ran over something that ripped a hole in the cover, which then left a flap hanging down that eventually caught a lot of air and tore the rest of the cover down.

I couldn't get a good search on the part until I found your post and got the part number. I found one on eBay for $80, instead of the asking price from Nissan parts dealers of about $150. By some incredible stroke of luck ... the seller lived 5 miles from me. What are the chances that a guy was selling this old part (that he had bought when he ran over something too, but never used the part) the same week that I was looking for it and that he not only lived in the same state, but in the same city and 5 miles away!

And today, I finally got around to trying to install it and found that all the clips are missing, so I did a search on the part number you provided and found some on Amazon for a fraction of the cost of the generics at the local auto-body store.

Thanks for sharing. Every little thing we do and document comes in handy for someone!

Hopefully we won't run over any more things. And the 2011 is still running strong, albeit with a 2015 battery in it (from the original battery issue warranty).

Next time it gets snagged, I'll probably remove it and try to repair with with some epoxy and fiberglass fabric to avoid spending much more money on it though. It feels like it's made of cardboard almost. I think repairing it before it gets completely destroyed is key.

My parent's Corolla had an issue when something happened and a flap of the shield started dragging, but it's made of metal and was rusted. I cut off the dragging part of the shield with tin snips and just left it like that.

Shot a video on the topic It's common for the attachment points to get damaged with impacts to the chassis panels. Yes, fiberglass fabric and epoxy works great to repair these panels, but don't overdo it. If the repair is very stiff, the next impact will just break it away from the flexible panel. The same push clips are used on the 5 chassis panels, and fender liners so if you're doing any work on these, get yourself a bag of 100, $20: https://www.amazon.ca/Lantee-Fasteners-01553-09321-Frontier-Pathfinder/dp/B01LZD8A7E
You'll break a bunch of clips removing them. I have removed all of these panels/fender liners for corrosion treatment...there's quite a few of these clips on the car.
