I have a 2005 Mazda Tribute S, 3.0L 6 cyl., and I am noticing a pulsing, slight vibration coming from the back end when I am at highway speeds. I recently had the tires rotated and balanced. Could it be the tires or something more serious like the rear differential?

SOURCE: Have a 06 Mazda Tribute

cupping is caused by poorly acting shockabsorbers probably have leaking from the shock struts and may need replacement. sounds a bit early for wear at 50k

SOURCE: Vibration after flat back tire of Mazda RX8

if the tire was run very long in its uninflated condition .. then it could have damaged cords or the belt ... or it could have heated to the point where the belt shifted .. that would unbalance the tire ... the tire should be removed, inspected for damage and rebalanced if ok .. its not a good idea to drive at 75 since the safety of the tire is questionable .. if the tire just sat for a long time underinflated but not being driven then it can take on a "set" or out of round condition .. that is temporary and will likely go away with continued driving .. driving with only 11 pounds wont take long to damage the tire ..

if you jack it up both ends off the ground,using axle stands to support it,then start it,put in gear and take it up to the vibrate point.you can get someone to carefully look underneath,and at the wheels,to see if any thing vibrating.DONT REV IT TOO MUCH.it might fall off the stands

The noise is most likely caused by the different wear pattern on the tire that came from the rear of the car. The difference in the alignment between the front and rear suspension systems causes the tires to wear accordingly. It will take some time for the tires to wear in to their new environment. The noise should go away gradually. You should also check your tire pressure to make sure you don't have an improperly inflated tire.

You do not steam clean any engines from
1985 on, or you will have problems with water
intruding electical connectors & more

Brake fluid won't be low
As the pads wear & caliper piston moves out,
fluid level goes down,not an issue

The ABS light you should already know is a Vehicle
System Malfunction & we have had those or similar
lights on the dash of all vehilces for 30 years
So nothing new at all. Check for codes,diagnose &
have the ABS Braking System repaired

Testimonial: "I added brake fluid and the light went back out. It had also just turned over to 100k so it could also just be an automatic thing. No more trouble!"
