Hood problems

[TYTILIDIE]

When I drive onthe highway, my hood starts shakin back and fourth. This makes me a little nervous like it could pop open at anytime. That Im sure wouldnt be fun. I have adjusted the rubber dealybobbers under the hood but it just pushed the front of the hood up higher than the rear of the hood and still shakes. Anyone else have this problem? How do you fix it? Ive contemplated hood pins just to be safe.

Re: Hood problems

The hinges might be loose somehow. Or the hood from the hinges. Look at those. Also, how loose is the release for the hood? That might also be loose and causing it to move around as well. (but probably not alot.)

Just some ideas.

Re: Hood problems

What about the non-adjustable "rubber dealybobbers"? They are called hood bumpers, BTW. There should be at least one on each side, possibly two (not looking at my truck right now). As they get old, the tend to compress, and not touch the hood any more. They are cheap to replace.

Re: Hood problems

Their is also a plastic strip at the back of the hood, on the wiper/vent trim peice. The is also is supose to keep the hood shaking down.

That plastic strip made a big difference on my truck. When I had my truck repainted they left that strip off and shortly after I picked the truck up it became real obvious something wasn't right.

Uhh...I hate to say this but mine screw in and out. Maybe thats the way you remove them but oh well. I say theyre adjustable.

Re: Hood problems

My plastic strip moves around alot on its own. Ill open the hood and itll be all to one side. Are they expensive?

Re: Hood problems

the piece on the latch that has the spring around it is also adjustable. reach through the spring with a wrench and losen the nut then turn the main piece with a flat head screw driver. i was having a lot of the same trouble with my fiberglass hood but it wasnt touching the rubber on either side. i ended up moving the latch piece up a good bit in the threads (i even took it off and added some more threads). that really helped except it made the hood a pain in the a$$ to close. i then found that cutting a coil or two out of the spring solved that problem.

if your running the stock hood im sure you would just have to move the latch up a little with the adjustment so the hood shuts solid on the rubber stops but fits the fender line perfect. :2cents:

Re: Hood problems

I take it back, they dont turn in and out. They just turn. My fault, sorry if I mislead anyone. Ill mess with it this weekend and see if I can get her to work right. It also is hard to open.

OK, I'm getting requests for the part number on this so I'll just repost
the original message I sent 4/6/01.

Here is the pertinent data on the hood shake issue. I got the bumpers
from a local GMC dealer - he said list was too expensive so he charged
less. I'm sure Dal could do just as well if not better - I was just in a
hurry. They order the bumpers and get 'em in within a coupla days. Part
number is in the narrative below from the TSB.

FLUTTERING CONDITION REAR HOOD EDGE #91-10-20

SUBJECT: HOOD PANEL REAR EDGE FLUTTER

The rear edge of some S/T vehicles may exhibit a fluttering condition. A
field repair has been tested and has proven effective in correcting this
condition. This is done by means of rubber hood bumpers (hood stops) which
exert a pressure to the underside of the hood. This eliminates the freedom
of motion that the hood is experiencing.

SERVICE PROCEDURE

To repair the condition do the following:

1. Obtain two rubber hood bumpers part #458306

2. Measure 8 1/2 inches along lower cowl panel from the inboard side of
the front fenders.

3. Place bumper so that the middle of the bumper lines up with the inboard
measurement.

4. Remove the old contact adhesive by sliding the hood stop against a
smooth surface. Using 400 grit sandpaper very lightly scuff the surface
areas to be glued for maximum adhesion.

NOTE:

If the placing of the hood stops under the hood causes the hood to rise
more than 1/18th of an inch above the cowl panel then remove some of the
rubber from the top of the bumper using a razor blade or sharp knife and
continue until an acceptable height is achieved.
