This has also been posted in the suspension forum, but I thought the body shop people may have better access to assembly drawings for this one.
I need some help/advice with the rear shock mounting flange on my truck. The truck is a 1990 Chevy C1500 2WD 1/2-ton. I thought the exhaust system I just had put on the truck came loose due to a clanking noise from under the truck, so I took it back to the shop, and they determined the passenger side upper shock bracket was loose. They tried to tighten the bolt, but said they couldn't get it to budge. I watched them try, but they didn't want to use an impact for fear of breaking the bolt, and not having the right tools to fix it. At least they were honest.
My idea is to soak the bolt with penetrating fluid for a few days, and then hit it with my impact gun. Hopefully it will break free, and not snap off.
They said there may have been a rubber shim, or washer between the bracket and the bed of the truck that may have rotted away causing the gap. I looked in the factory service & repair manuals, but it doesn't show the connection of the bed to the frame and brackets.
Does anyone have access to an "Assembly Manual" style drawing for this area with all the nuts, bolts, grommets, and washers shown?
Any other ideas are welcomed. It's snowing like h**l here and it's in the teens, so outside work will be limited.
I'm not taking the Chevelle out of the garage unless the rear end falls off the truck.
Thanks in advance,
