W900L excessive hood shake

Been working with hood most of the day today. I've been all over it trying to find the problem and all I can come up with is those metton braces seem to have just gotten tired/fatigued. Lots and lots of flexing. I cut and added some thin aluminum pieces on the back side of the rear brace. The aluminum is thin enough that it still has a little flex to it but it stiffened it up tremendously. I've yet to drive it since I done this but I can tell it's gonna be a big improvement, or atleast I hope so.

 

Thanks for the compliments. I made me some templates with cardboard and cut them out of an old road sign I had laying around. I should have probably painted them but a ran out of time and you can't really see them anyway.

They did help a good bit. Stiffened the rear of hood up a good bit but I still got some shake I shouldn't have. May have to do the front brace the same but it's gonna be a little more involved if I do. It's not as thick as the rear brace and I'll have to take the grille out to get to it. Gonna look it over some more over the weekend.

 

This is my W9 with the hood trouble. I think most of my hood trouble is due to what I'm hooked to in this pic. Lol!


This is a recent pic.

 

I still think it's in the hood somewhere but I do agree with the part about looking other places. I've done this some and havnt found anything out of the ordinary so far but I'm gonna keep looking. I'm going to try finding something I can stick in the aluminum parts that sit down on the rubber stops/hood rests tomorrow and see if I have any flexing there. Not sure how to check the mounts where the front of the cab mount to frame because they aren't easy to get to but I'm gonna check those out. The brackets on the front of rails where hood pivots bolt to are good. Not sure of much else to check.

 

You got that right! I haven't pulled containers in close to 3 years but I figure those have played a part in the problems I'm having now. At the same time they were resurfacing Hwy 78, which I ran daily, and it was extremely rough for close to a years time. It was rough on my truck.
