Well ,2004 tribute there is a noise, all the time and I was told that may be from tires,that is from tire shop, but tires are still about 80% left, and if I change tires and the noise is still there what should we do. So we don't see any bumps on tires. It is hard to describe where is coming from.

I think you have a tire problem possibly a tire is separating. diff will make loud whining noise or banging/grinding metal noise

Hello,
I do agree with the person who mentioned
" Tire Noise". A few moments spent with a knowledgeable tire dealer will help
in your choice when it comes time for replacement,
Enjoy your Benz. A little homework will quiet it down real nice.

tyre noise depends on the tread pattern/road surface material.so it is a bad tyre depot that cannot tell you which are quiter than other makes,same as ones that last longest. most customers buy the cheapest they can get and complain about the car...)any block pattern tyre will be noisy(look at the tread pattern on a limo)the only way you can be sure of getting a quiter ride is to email the maker direct.BUT be warned you may pay 3--4 times the price of a "standard tyre" and any suv is no limo......no block pattern, no grip in mud/snow....

raise the car on that side grab the tire and see if has any( play) moves from side to side considerably.

we have a 2003 saturn vue which we installed new tires on and we noticed a noise about 6 months afterwards. it sounded to my wife and i to be loud road noise from the tires. the car was driven for 6 months and we decided the noise was annoing. had the tires checked only to find it was the left front wheel bearing which was replaced and stopped the noise.

chevrolet uses tire pressure sensors for the system, check the tire pressure in all tires including spare and they should be set to about 38psi. If any of the tires are low it will trigger the abs because the abs system goes off wheel speed and a low tire will throw off the reading.

I might try a different shop. I have never heard of a broken Stud nut making any noise I hope they diagnosed a problem with the noise. Also in-experinced tire tech's over tighten lugs with their impact wrench and snap broken studs

I had the same problem on a 2003 Kia Sedona where the front end would vibrate excessively while accerating at freeway speeds. Over time it got worse and was noticable at lower and lower speeds and while just maintaining speed, but went away when I took my foot off the gas.

It turned out to be the inner CV joint on the passenger side. You can check for this by grabbing the inner and outer half axels with large vice grips or slip-joint pilers and turning them in opposite directions while listening for crunching or "loose parts" noises.

The CV is sold with the axle so I just bought the outer half axle for $80 (which has the inner and outer CV joints attached) and replaced it. If you do it yourself, make sure you have a ball spline fork, a hub puller tool, and a big torque wrench for putting the bearing assembly back on. You can rent these at AutoZone.

The bad CV joint also caused the bearing to go bad. It had burn marks and made a grinding noise while turning. It was very hard to get out, so I had to take the assembly to a machine shop to have it taken out and the new one put in. $35 for bearing and $30 for machine shop work.

After repair, I took an 800 mile road trip that weekend with no problems other than barely noticable vibration from the driver side at 70+ mph. I figure vibration was so bad pre-repair that it messed up something on the other side as well, so I'll check out the driver side bearing and CV when I get a chance.

It sounds like you have a wear pattern in the tires. If the tires wear rotated from left to right this problem will be exacerbated because they are going in the opposite direction. If you can't live with it then rotate back to the original positions or replace tires

replace the stablizer bar links and the struts
