My 04 trailblazer intermittently sounds like it is running over a rumble strip, then it stops after applying brakes a few times

I don't know how exactly to explain it. Rumble strips are those grooved pavement areas on the sides of highways and if you run them over, it makes a loud noise under your tires and your whole vehicle shakes. I brought the car in for service over the weekend and they replaced a front wheel bearing and repaired a front caliper on the opposite side. But then Sunday, the car started doing the same thing.

Did it make this sound before you brought the TB in for repair? That sound is not normal and is not common like all the other "sounds" you hear from these. The only thing that comes to mind would be one of the calipers sticking, causing it to shake. Is it constant until you press on the brake? Sorry you had to replace the wheel bearing, expensive little buggers. Did it make this sound before you brought the TB in for repair?

Yes, that's why I brought it in, in addition to the scraping noise I would here when I turned the wheel to the right. (I hear ya, I just spent over 500 that I didn't have to begin with but I"m 8 months pregnant and have a 14month old so I want them to be safe.)

The shop you brought it to said the caliper and wheel bearing was causing the sound? The shop you brought it to said the caliper and wheel bearing was causing the sound?

They said they had to replace the left front wheel bearing, , they cleaned and lubed the right front caliper, and cut back some piece of "tin" from the back right that was rubbing.
