2010 2500 Yukon XL 6.0l

Rear exhaust driver’s side. Bolts broken and leaks. Have the clamps. But need help with getting that dam bolt out that holds the ground strap.

Guessing front drive shaft needs to go to get access. Appears it’s a 16mm bolt. Assuming I’ll have to use the open end wrench because of the ground strap? Looks tuff. Any help or threads you know of you could point out?
I’ve read some that say you can get ground strap bolt from top??? Can’t see that unless some sort of special wrench?
Anywho thanks great forum.

My stock bolts have 15mm heads.

So through some reading and I got it done,90% fixed.

Both rear bolts are broken on drivers side,seams theirs room for a 5th bracket at cylinder 5-7? I see two threaded holes in the head?

How much are you guys tightening these clamps? Do you do it when its hot?
Cheers,

So I guess no clamp is made to push at the bolt between 5 and 7,threads are there.I may try to fab something up.

Awesome, was able to tighten the bolt a little more noise is gone yay.
I bought this unit with this leak for a good discount, pretty happy that I was able to fix.

Onto other fixes.
