couple of issues

Just lookin for some advice about the next predicament in owning my truck.

First issue is right around 38-45 mph there is a slight rolling/scraping sound that happens about every 150 feet. I just had a cv boot replaced but normally my vibes start at about 54 mph so I'm kinda confused. The shop that replaced it did take the wheel off and what not so I'm beginning to wonder if they may have messed something up in the process.

My second issue is with the hood. It seems that in very windy and bumpy conditions the hood latch unattaches to a degree allowing the hood to shake up and down about 1". Every time I open it up and make sure that its closed and closed correctly it will pop back up after driving it around town.

Any help is appreciated, thanks

 

The hood is out of adjustment where the latch is. How loud is this "rolling/scraping sound"? I think it could be something in between your a/c compressor and it's clutch. (very slim chance that this is the problem because you live up north, you probably do not use it)
Try driving without the A/C on.

 

I'll have to check out the hood latch thanks. The rolling/scraping sound is more of a feeling but a very slight hum/rub to it but we do use a/c haha im only in missouri, but then of course its december and 18 degrees in the morning. I don't know the issues attributed to wheel bearings but isn't that what would make that slight vibration/hum/rub/scrape whatever it is?

 

If it is the wheel bearings, easy way to check is jacking up your truck and wiggling the tire. If it does not budge they are fine.
I am throwing out random stuf now, but I just replaced all 4 of my cv boots a wile back. In the center of the hub there is a black cap. When you take that off there is a huge nut, and there should be a retaining washer with a retaining clip. If they did not tighten the axle nut or put the retaining washer and clip this could be your problem. Allowing the cv axle to move a little bit allowing to make your hum.
