2004 Chevy, HD 2500, roaring in front end

Bad front wheel bearings will make a loud roaring sound, and get louder as time goes by, check this out! God-Bless!

Roar can often be associated with failing wheel bearings, but they usually don't cause severe vibration, maybe a little bit when turning. Vibration in the drive train is most often associated with struts and/or CV shafts/joints going bad. If you are sure the struts and strut mounts are good, then I'd have the CV joints looked at.

The half shafts o.k.?

does the roar change with left or right turns? most likely a wheel bearing, Dodge has poor front ends. or..is the brake dragging? the rotor would be hot after driving, discolored, smoking.

Does the vehicle make any noises while driving? If there is a "growling or roaring " noise associated with the vibration, check the right front hub bearing. If there are no noises and only vibration, check the right front upper ball joint and control arm bushings. The Trailblazer's upper ball joint and control arm bushings become worn and cause the tire and wheel assembly to shimmy while driving. The vibration stops when turning left because of weight transfer to the right side which keeps the wheel steady for a moment. Also, check the tire for irregular wear.

Sounds like you have a wheel bearing problem. Jack up the front end so wheels are off the ground. put your hand on the spring on the strut then turn the wheel with the other hand. If the bearing is bad you will feel the vibration/rough spot in the spring. Noise will get louder or diminish when you peed up or slow down.

You are on the right track. You may have overtightened the tie rods or the sway bar links. Whenever you do this much front-end work, you should always get the front-end re-aligned. The front-end mechanic will probably find and fix this as a normal part of the re-alignment at no extra cost.

First try rotating the tires to the rear. Does it go away? If you apply the brakes does it pull to the left? Could be a draging caliper or the slides may be hanging up.

First just crawl under it and grab your axles and see if you can shake them and get any movement from either of them this will tell you if you have a loose CV joint or not .. thanks Jerry holler if you need more .
