Hood movement

If you can get a stack of pallets with some carpet on top so it will not rough up the pant, then you can replace the bushing one side at a time

 

That way you have a hood that shuts right

 

It's all going to depend on whether the bolts are fixed or removable. If you are able to remove the bolts, you should be able to replace the bushings without removing the hood (with the help of a prybar, probably).

 

If you think those are a pita, you should try a T660....
If a paccar is a paccar is a paccar....the bolts go through a steel bushing and both the bolt and bushing can wear down, and those will need the hood to be supported.

 

Yep, the pins/bushings on the hood itself

 

My main pins were worn down about 1/16" all the way around. Even with the hood supported, I had to drive them out with a 3# hammer.

 

If it's once in a while the truck is probably on uneven ground. If not, there are quite a few adjustment processes Peterbilt has. If I recall correctly there is up and down in relation to the front bumper - Fore and aft in relation to the cowl - up and down in relation to the cowl - side to side in relation to the cowl.
