rumble at highway speeds

Luk3 said:
No. What would I be looking for?

Don't know if it could be related but I am creaking over speed bumps on both front and rear left side.

My front end has creaked/popped/short quick vibration ever since I got my car towed long distance. Haven't gotten under to check what is going on.

I was under the car yesterday checking for loose parts in the rear and noticed this cracking and splitting. Could this be causing my problem?

I wouldn't be surprised to find something like this.

Good luck on figuring out what the noise is coming from!

a vibration is usually the result of something spinning. Worn boots and joints would result in klunks and funky stability. I've never really had one cause a humm/vibration.

My money is still on wheel bearings, cv axles, or driveshaft.

people in this thread report similar symptoms to mine (high speed vibration)
and the fact that my toe links are shot may or may not be my solution but they still need to be replaced.

Funny thing its your thread from a year ago kumba :)

Deeza Part# JAL607 is the correct part right? rockauto still has them $142 for a pair shipped.

That didn't actually fix the vibration like I thought at the time. Did fix the clunking I had though. The wheel bearing vibration would come and go, it wasn't necessarily constant all the time. Some times it was smooth and quiet as you could ever want, then the next time it'd start humming and vibrating the whole car.

It wasn't until I took a road-trip up to Saint Louis that it got loud and did it all the time. I had actually fought that vibration ever since I owned the car and never found it. Soon as it was replaced all the vibrations went away finally. Only reason it was finally diagnosed was cause of Mr.Howie up in St. Louis. I had to go through 4 or 5 techs down here until one would say "Yup, bad bearing".

I have a pair of rear bearings ordered a couple weeks ago.
I'll probably do both at the same time after the holidays. Maybe I'll throw in pads and rotors while I'm at it. The cosmetic mods will have to wait grrr
 
What about the exhaust harmonics thing. I hear the hum from mine at less than 60 and don't hear it when I drop it into 4th.

I get a similar hum from the rear between 35 - 45, but only when the car is driven in ambient temperatures under 45 degrees and only when the car is first driven. It fades away after about 10 minutes. There is no vibration.


Now, I haven't been able to confirm this, but I think it is better since I replaced the rear brake rotors.

In case anyone ever finds this, I found that the rotors had no effect.

I'm considering the rear bearings now.

I just replaced my rear toe links and rear sway bar end links....it eliminated my high speed vibration.

For same price you can get the sway bar end links included.

They're Deutsche Parts links. I ordered my rear sway links from them a few months ago and they're holding up fine. They have grease fittings.

I'd only recommend them if you don't plan to keep your car for very long.

Moog or oem if you never want to worry about them again.
 
Seems Deutsche is not very good at all. I'll go with the Deeza tie rods on rockauto.

The parts I got looked/felt as good as the oem ones. Plus grease fittings. I can't vouch for the quality of the metal, but the tolerances all seemed tight.

Plus at that price point I don't mind taking a risk. They're not hard to change at all. If it were something that were a bit bigger PIA and had a greater effect on handling/wear like front ball joints, then I would have went with Moog....which I did:D
 
Just an update on those Deutsche parts rear sway links...

When its cold out they're extremely noisy. I get hollow thuds and clanks for the first 5-10min of driving when its cold.

I'd recommend staying away from any part with their name on it.

I'd put my money on you needing new sway bar bushings.

Yeah that did cross my mind, they looked alright from what I can see. Its just weird it only happens for the first little bit of driving.

I was under the impression its mostly the front sway bar bushings that are troublesome, or go before the rears. Anyhow I guess I could disconnect the links for confirmation.

Mine need to be replaced...front and back. They 'look' good, but with the end links off there is a ton of play. That seems to be what I've seen in other people's bushings here too....they look good until you get them off and compare them to the new ones.

Since you need new bushings, do you notice the noise more when its cold? Replacing the rears looks like a nightmare..

Good question, I hadn't thought about it. I have thought it seems more noticeable at times....though I hadn't linked it to temperature.


Now you're going to have me thinking about it all the time....

If not, I figure (in my case) it's just the substandard rubber Deutsche Parts uses. When it sits in the cold it probably hardens up and shrinks causing noise when you first drive it.

It doesn't get cold enough outside to shrink steel....and even if you do manage to shrink steel, it's thousandths of an inch. like .002.

If anything rubber would be affected by the cold much more than the steel would.

I said rubber, but yeah hard shrinking steel haha.

Missed the rubber part you said. Really the sway bar end links and toe links are almost all steel. Actually when I used to work in tool and die we would freeze the guide pins to shrink them and make it easier to press into the shoes.

But my point is that it's likely the rubber sway bar bushings if it's cold. And that's one of the reasons that people use poly bushings because they're not affected by cold temperatures as much.(which exactly fits what you're describing)
