heat shield rattle, please help

[jhanley]

Where can I find the best price on replacement heat shields.

Since my shields are fairly corroded, I do not want to clamp or add bolts. I would prefer a replacement. Please advise

Cruiserdan (and his partner Beno) are always my OEM parts recommendation.

This heat shield rattle along with the ticking sound is driving me crazy...I cant afford the headers so I bought the heat shield for now

Best fix for the heat shield is a $3 hose clamp. I did that on my old 99 and never heard a peep from that point forward.

Hose clamp is key.

My rattle is back. Got the hose clamps on and it or something is still rattling. Hoping the element inside isn't busted up as what happened to one of my cars with "high flow" cats.

^ I did the hose clamps thing and it helped but I eventually replaced the shields. That was 50K miles plus ago - now the rattles are back!

I just took mine off.

Reviving an old thread - what size hose clamps is everyone using to get rid of the heat shield rattle? I'm getting a bunch of stuff at the hardware store today and want to get some clamps to fix it. I searched quite a bit and never saw a reply with the best size clamps. TIA

Did you read this one? It's in the FAQ.

It does seem that opinions vary... Anywhere from 4.5" to 7". I'd go 7" and cut off the excess if needed.

I use a bunch of stainless safety wire to stabilize my cat shields, they only rattle at start up now and once warm they are quiet.

Just improvise with clamps, wire, etc... hit the pipe with a rubber mallet to hear if you're getting close. Definitely not an exact science.

Thanks guys - Dwight I did find that thread actually. I was just using the search and went back about 5 years but the thread you listed was a decade old It's cool to know there's good info that goes back that far!

The crew at Toyota told me if I went to a Midas they could weld it shut along the seams. It would run about $150. Has anyone had them welded before?

 

[DanInDenver]

I believe I used the 4.5". Best fix/mod, now no rattle at all. All I hear is the tick tick of the cracked headers....

Given the cost of clamps the return on welding isn't worth it.

I removed my shields too. My right cat still rattles. hmmmm....

That sounds really expensive! I had a CJ5 with a couple loose bits on the exhaust and I went to a local exhaust shop (in Flagstaff however), and they welded a couple brackets/hangers and cleaned up the mounting for around $30. Maybe I just had good luck as a college kid, but I remember thinking that seemed like a fair if not great deal.

Wonder if this serves any purpose? Last few weeks, my lx has something that been rattling. At first, I thought it was a cat shield but it turns out to be another spot. A shield that covers the pipe that goes over the shaft… from drivers side over to the passenger side. I removed it because I did not have extra clamp nor anything. Beside my muffler needs replacing. I figured I can take it off for now being that it's winter. But I got to wonder why… what purpose does it serve?

I've been wondering what that sound was.

This is an old thread but I have been experiencing the same rattling issue with the catalytic converter heat shield. I took it into the dealer and was quoted $700 to repair just the passenger side. Apparently, the entire exhaust has to be removed just to get the heat shield out. I ended up using a hose clamp as recommended. In my case, there was an existing clamp that did a pretty good job securing the two halves together. It was slight movement against the pipe inside that caused the noise so I used a second clamp secured against the splash shield to pull it tight to one side just slightly. This has been working pretty well so far. I'm interested to hear if anyone thinks that price the dealer quoted me was reasonable.

I tied one of mine together with some Mechanics wire that you can at any parts store.

I think that another one starting to become loose because I hear the same noise when I slam the driver's side door.
