craked frame

[adamforsythe]

Hello,
When I was tearing into my 1985 K5 (pulling tranny/t-case/engine) I noticed that both of the frame rails where cracked right under the tranny cross member.
When I was yanking the engine, tranny, etc on my 1986 K5 I found the same thing but on one side. Is there something that I can do to keep that cross member from putting stress on my frame?
Thanks
Adam

I have broken my frame in pretty much all of the common spots, but never by the tranny x-member. I would love to see a couple of pics of where it is cracked? Do you have spacers in there to lower the Tcase? Are all of the bolts tight? How are your tranny mount bushings and motor mounts?

Good question, my frame is cracked in the same place...................

when I bought the frame thats under mine now it was cracked on both sides where the crossmember bolts up, the PO had wheeled it pretty hard, I just stop drilled the cracks, then clamped the cracks back together and stick welded them and ground the welds flush. No more problem!

Just curious, but was the crossmember flat against the frame, or were there spacers between them ???

Hello,
I don't have a camara right now. I do have spacers on the crossmember.
When I yaked the engine and tranny all of the mounts where good.
Thanks

Hello,
It has spacers.

Were they between the frame and the crossmember dropping it down, or just on the bolts under the crossmember ???

I'm just thinking because the stock spacers are small in diameter and may be pushing in the frame when between it and the crossmember. Thinking larger ones to prevent cracking.

Thanks for the info.

Hello,
I believe they where under the crossmember.

Is your crossmember one of those that bolts to upper and lower section of the C-Channel frame, or one of the ones I've seen a few of that only bolts onto the lower c-channel section?
