carnage

[surpip]

so it seems my truck likes to eat the top bolts on the adapter, going into the tranny. When i got the truck they were both broke, anfter the rubicon trip(i guess thats what did it) they are both broke again

is there a good fix for this? this time they broke, i had replaced the tranny mount, so i am not shure what is causing this to happen.
any ideas?

usually the threads strip before the bolt breaks. it shouldn't be twisting thats breaking them or all 4 would be broke. what grade bolt are you using? 8.8 or 10.8?

i got them from the chevy dealer last time, so what ever is stock
guess ill have to go with a higher grade this time
always somthing

 

[big83chevy4x4]

they are probably grade 8.8, equilent to a SAE grade 5. probably wouldn't hurt to try a 10.8 bolt.

do you have the support brace that goes from the tcase to the bellhousing bolt?

 

[surpip]

yep shure do
guess ill step up to the higher grade, im shure they wont be easy to find out here

Mine stripped once. I drilled out the holes and helicoiled all four holes, and haven't had a problem since. I think it is just a weak design. Thats a lot of weight hanging off the back with only threaded aluminum holding it on.
