Hello Everyone. New user here and hoping someone can help!! I have a 2004 Chevy Tahoe 5.3L 4x4. Recently it has started vibrating when I hit the speeds of 45-55 mph. It's feels like I'm hitting rumble strips. If I let of the accelerator and accelerate again it seems to stop. Nothing in the front end appears to be loose. We did change the Pittman arm, and the idler arm and housing just in case. We have also rotated my tires to see if the vibrations would switch locations. (The vibration appears to be front passenger) I am at a loss and the vibrations are driving me crazy!! Anyone have any ideas as to what it can be before I take it to a garage where its 75.00 an hour just in labor? Thanks in advance!!!

 

Probably:

Wheel Alignment


Bulge or Blister in tire

Unbalanced Wheels

Worn Motor Mounts

Worn Shock Absorbers or Struts

 

Ahhh! Nothing scarier than that Death Rattle. Did the wobble change any when you swapped tire locations? If not, it's probably not a tire issue. With so many components recently changed, I'd start checking there-looking for loose bolts and nuts on the tie rod ends for example. Are the tires stock or oversized?

 

I ended up taking it to a tire shop. They recounted and balanced my tires. I also got an alignment. The vibrations have seemed to stop!

 

Remounted not recounted lol

 

Woohoo! Good work, hope it is resolved
