The Story of SKETCHI - 05 ZHP Sedan

[Vas]

Started today on the csb and guibo. Pic below of the old parts.

Guibo is cracked pretty bad. Csb was torn and just barely hanging on. Bearing inside of it was dry as well

New csb is installed as well as the guibo and back together it goes.

Not a terrible diy considering I didn't remove the exhaust.

Impressive without exhaust removal!

Man I didn't really want to remove it. Mostly because of the nuts that hold the headers to the exhaust. I knew they were going to snap and would require drilling them out.

Also took the vehicle for a drive and the vibration is now gone.

Great Job!

You have got to let us know what the trick is to removing the entire driveshaft without removing the exhaust. I also have an increasingly worsening driveline vibration and am planning to do a transmission filter and fluid service (auto), and replacing the guibo and CSB. My header to exhaust bolts and nuts are also really rusted and would probably have to be cut and drilled out. Not having to remove the exhaust could shave hours off of this job and also save on $$ replacing bolts, nuts, and gaskets. The pictures of your old CSB also makes me terrified that mine looks the same. The drive shaft must have real been flopping around under the car.

For the exhaust, I just removed it from all the hangers and dropped it down enough to be able to remove the heatshield and driveshaft. There was enough flex so I was not worried about cracking any welds.

As far as the csb, it got progressively worse over time. Pretty sure the long road trip I took just made it worse.

I was thinking to take the car to an exhaust shop and have them remove/replace the studs. Would save some time but not sure of the cost of having it done.

To get the header bolts off, you just need to heat the crap out of them until they turn red. They'll come right off.
If one of the studs break, you can press it out with a big C clamp and a socket. Theyre just pressed in. No need to drill out.
You'll get sticker shock if you buy the nuts and bolts from the dealer.., around $50 or so but the nuts are copper infused to help keep them from seizing. Use plenty of anti-seize compound and they'll come right off the next time you need to remove the exhaust system.
I used heat on both my exhaust and San's exhaust when we put my TSE3 on it. The nuts came right off. The threads were rusted off my bolts so I had to replace but San's were still in good shape so we didn't need to replace. We just put it back together with some copper based anti- seize and new gaskets and it was GTG

It's already been a year since we swapped exhausts. Time sure does fly
