Exhaust hangers

[Dandy2012]

Hey guys little background, was driving in very serious rain today was extremely heavy and a really loud knocking noise began. You could also feel it in the floor pan. Was very scary. After some extensive research it appears that it's an exhaust issue. Apparently the cold water on a hot exhaust = very bad vibration, shaking and is causing the exhaust to hit the under side of the car. One chap said he had fixed this issue by upgrading his exhaust hangers to stiffer polyurethane ones. My questions are;

How many exhaust hangers are there on a vz executive standard exhaust system?

Are all the hangers the same? (Shape)

Can you get polyurethane replacements and where can I get them?

Also any tis on replacing them would be great

Thanks in advance.

So why don't you get under the car and confirm

Its 4 hangers from memory and you may need the holding clips

If the exhaust wobbles then yes the hangers deteriorated

Should be two midway and two rear muffler

These are what the hangers look like, there is nothing wrong with the genuine Holden ones, as uniacidz has mentioned, get the clips too

Thanks guys I'll track down some genuine and replace the lot just incase it's my understanding they are not overly expensive. I will replace the clips also

Well my link for the clips is now gone so updating here.

I personally got 4 of em cos they are fiddly and hard to remove.
Need to get like a small screwdriver and wedge out the clip part that is in the small groove

Trust me you will see it when you need to do it.

Whole exercise including the hangers should be round $20

Make sure you know ya prices before committing to Holden Genuine

I most likely will just use the items you have linked to so thank you very much for that for the sake of less than $50 I am going to replace all of them regardless of their condition just for my piece of mind. Thanks again for the great advice and also uniacidz fantastic parts right up. Great spare time reading material

Remember a flat head screw driver to remove the clips
Once you done the first, its easy

Whilst ya there check all flange bolts and there's a support bracket, closer to the cat converter side and just check all bolts

Number of times I had to redo them up or bolts come off completely and needed to get a.new set of bolts and nuts

And if you do it, make sure under ramps or a good jack and stand set and not the factory scissor jack

Too much info I know, but these are what I picked up on under the car

 

[Dandy2012]

No problem thanks for that I will make sure I check everything whilst I have it up. Jack stands are of course a must I would never get under a car without them but great tip.

Hello,
Would anyone know if the black exhaust hangers are ok to use?
I've just got 4 rubber exhaust hangers from repco, that's what they said is for a vz Commodore,
The old ones on it are red ish,the new ones are black,
They should be fine to use right?lol

If they fit, they are fine.
