Cracking of Radiator Support

[Edodrian]

Anyone else experiencing this as well? I have noticed it bad lately and I believe it may be unstoppable.

Its around the A/C condensor and along the top rail of the cross bar.
Also the flat sections next to the washer fluid tank and exact same area on the passenger side is doing it as well.

Near passenger headlight

Surge tank bracket broken also.

I have tried what a few people around here mentioned about stopping cracks. About drilling a hole at the end of the crack. It seems to just change the course of the crack, a few it has stopped though.

I'm thinking its due to the body lift.

Never seen the cracks personally. My upper brackets are pretty heavily rusted, something I've seen/heard of a lot on our trucks.

My lower support just plain fell apart a while back. Totally rusted out, crumbled, and fell out. Also something I've heard of and seen. It got replaced with a piece of 3/16" x 1" steel flat bar.

Yeah mine is cracked near the headlights. Both sides no body lift.

A little bailing wire and it will be fixed.

In reality I wounder how that part has that much stress to crack. I understand the rusting a lot more.

You were 1/2 way there when you drilled the small hole to stop the crack. You needed to weld it all back together at that time. The cracks are from the metal flexing, it is not a common issue, but it is known to happen.

Mine are just rusted to crap but no cracks. I guess I need to make a set or something.

I doubt the body lift was the cause of the cracks but since a body lift does increase the leverage and therefore the stress on the body when flexing, it may have accelerated their growth. The cracks would likely be due to metal fatigue from either pressure/twisting forces or from vibration. I haven't noticed any on mine but I'll take a closer look then watch carefully after doing a body lift next month.

I second this. Its just wear and tear.

Well this is interesting. The body is cracking and clicking loudly at the cracks over bumps. I think its due to the HEAVY diehard battery I installed. I guess some welding will be in order. My front is cracked in several locations. No accidents no body lift. Just rough roads.

Same places here man. Including the exact same spot on the other side. Also found a spot right below my air cleaner box under the hood. Got all of them welded up now and most of my noise is gone.

Yeah its odd must be just poor metal quality. There doesn't appear to be faults in the engineering. I guess I'm no engineer though. Yeah there is cracks everywhere top to bottom some areas aren't even loaded with truck mass. Was considering perhaps adding bracing or supports but honestly wouldn't know where to begin. Looks I'll be using the metal hot glue gun.
