Use a good spray lithium grease instead like 3-in-1 or CRC.

 

Ive got this problem. Any idea on the dealership costs associated to change this?

Thanks

 

Steve (at Simone's Performance) gave me some good advice on the whole G35 hinge issue. It's really important to look after the hinges cause he has seen lots of paint chipping on the fenders due to neglected hinge maintenance. I watched him use generous amounts of a spray lubricant (probably graphite grease??) and then spend a solid 5 minutes working the lubricant into the hinges by lifting the hood up and down. For a car that's seemingly so well built, the hinge issue is surely an "achilles heel". I wonder what the engineers were smoking when they figured this one out?

 

It is going to take you several hours. It is easy to do, just takes some time.

 

So from what you are saying, if the fender currently rubs with the hood when lifting/lowering the hood, all we need to do is lube the hinges and the problem will go away?

 

Ha ha no. If the fender is rubbing now, the hinge is already bent. A little lube is not going to unbend them

 

Hehe...I was hoping for a quick fix

 

Obviously if you follow Steve's advice to maintain hinges, you're starting with a straight set. If the hood is already rubbing on the fenders, the hinges are already bent, and it's a little late for preventative maintenance. My point (and of course Steve's point) is these hinges are not very well designed - and with lack of maintenance, can cause expensive repairs to hinge mechanisms and paint jobs. "An ounce of prevention is worth a pound of cure" - or something like that.

 

The dealer replaced mine under warranty recently while my car was in the body shop. I wasn't aware that there was a problem until they brought it up and volunteered to change them.

 

Holy chit. I've never heard of this. I'll have to start lubing mine then. The hinges must be really crappy though, because our hoods are so damn light.

 

Happens alot. Sadly. Very weak hinges.

 

Back from the dead. Anyone know what these hinges go for locally? Anyone ever buy 3rd party hinges? I do not imagine them being much worse than the already poor quality OEM hinges. I think I am going to undertake this job as a weekend project. I do not like the fact however that the fender has to come off - something tells me I will break bolts and run into alignment issues...

 

The hinges sell for about 100 dollars at the dealership.

I bought a set off a member that was parting out a totalled car for 30, but when they came, they were bent too. ha ha

Ended up just getting rid of the car and getting a G37

 

Now THAT is a great solution, haha!

Mine started to bend a little, just enough to rub, but a shot of lithium spray grease eased them up enough so they work fine. Reminds me, it's time to do it again.

Guys, don't use WD40, it's more a penetrant than a lubricant and it doesn't last. Get this stuff instead:

Thanks for the tip. I am going to get myself a bottle of that stuff and hope for the best...worst case scenerio Ill need it anyways to lube up new hinges, if I absolutely have to get new ones (hopefully not, but it looks like I will).

A G37 would be a great solution, but the 370z is my next performance car (hopefully in a few years heh)
