Hood rise while driving (14 Viewers)

[FIDO96]

I’m getting about 1/4” to 1/2” rise in my hood as I drive. The hood is securely closed but I’ve never had this any any other vehicles. Is this just an old FJ80 thing or is it possible when they reassembled after paint they didn’t set it correctly. The gaps are prefect when parked.

Best pic I could get while driving:

Adjust the little rubber isolators on each side a little higher

It's not normal for the hood to rise like that. While raising the little rubber pads on each front corner will tighten things up, it could just hold the hood up too high.

You should be able to simulate this while parked to figure out what's going on. Maybe the latch isn't securing the hood properly, in the fully closed position. Maybe it got knocked out of adjustment somehow? Maybe something is bent or broken in the hood, core support or latch setup?

I'd want to know exactly what's going on before driving it more. I've had a hood fly up while driving, luckily on a junker at low speed, but you really want to avoid this event.

The surface from the fenders, above the lights, and onto the front of the hood should be relatively level as it transitions from fender to hood both when parked and driving. The hood should latch in two positions. An initial position that is just the hood release handle, under the front edge of the hood, holding it down and the 2nd position the fully closed position that requires the hood release below the steering wheel to be pulled.

Totally different issue, but if the hood is raising or fluttering in the middle then the adhesive between the inner structure and the outer skin has failed. That's a common issue and relatively easy to fix though again, it's not related to the front-edge of the hood staying securely in position after the hood has been fully closed.

Good luck.

Already mentioned above

FWIW

Has the vehicle ever been in a front end accident?

Has the hood ever been taken off or replaced?
Do the hood hinges look like they've been moved, loose/bent?
Does the hood latch assembly need adjustment?
Does the hood latch bracket, radiator supports, inner fenders, etc look tweaked (bolts turned)?

Take some photos of the hood hinges (showing the bolts to the hood and where they connect to the body) and post them up here.
Same for the hood latch and bracket, bolts to the latch, etc. to show if anything has been moved.

not normal....

I’m going to say it’s not latched all the way and only on the safety.
Something needs adjusting.

i bet the rubber tips are gone now due to age!

The rubber stops the hood from going down not up.

I'm going off of my memory at work but I thought there are rubber tips on top of the adjustable pegs! I was thinking these tips are worn through, which has created the extra play.

I just fixed this on mine. The rubber was compressed enough that it had just enough slack to go up and down from the resting position, instead of just up. This can be checked by going to wiggle the corners of the hood.

Just in the corners or is it coming unlatched up to the safety?

I have had this occur driving west on I-40 in New Mexico into a substantial headwind (on the nose or 10-20 degrees off to left or right).
No hood sheet metal delamination, front end as it left the factory, and slight stink bug (front end slightly higher than rear).
Pressurization of area in front of radiator and below front of the hood) is a likely cause.

Could be just the angle of the picture but it looks like the hood is an above the fender line.
I have adjusted the rubber stop my self before but not so the hood was higher then the fender line.
OP seems to have left the chat.

I finally got home at a decent hour tonight. Several things I’ve noticed.

1. We know the front end had previous body work when I had it painted. And the hood did come off. There is a slight bow in the hood about a foot from the leading edge when parked. This is what I see as I drive.

2. Had a coworker pull along side me as we drove to a project. Front of hood is low and secure. No movement

3. My rubber bumpers are toast. I’ve ordered a new pair just to have a little more rubber making contact.

4. I don’t believe I’m having any actual movement. Depending on my seat position the bow in the hood is more pronounced based on my line of sight
