front end making bad noise

front end making bad noise

Postby zackattack [OP] » Jul 30 2012, 11:29pm

I thought i had a bad wheel bearing as the truck was showing common symptoms of that in my 2002 gmc sierra 1500 4x4. SO i went and replaced the driver side wheel hub as that's where the noise seems to be coming from. after replacing the hub the noise is still there, best way to describe it is that it sounds like a big rigs engine brake. it happens from 55-? (haven't taken it above 60 to loud/ bad vibration) any help would be appreciated thank you.

the funny thing about wheel bearings and ball joints is that it is always the side that you think is not making noise........... jack it up and spin the wheel fast (have someone spin it for you) and feel around by the knuckle.... you should feel a grinding if a wheel bearing is bad

we did jack up both sides to compare didnt feel the knuckle to feel grinding though. i did replace the passenger side last year. the side i replaced was making a loud grinding noise so it probably needed to be replaced. so within a year and a half both front bearings have been replaced.

i am unsure of how to check the front differential. but that has crossed my mind. i should also add the truck pulls to the left (could be unrelated not sure has done it for almost a year now even after multiple alignments from multiple shops)

What about moving the tires to the rear and see if the noise follows, just to eliminate them...

My truck made a noise like that above 35. The factory tires were wearing funny, and causing a noise. Replaced all tires and have put 50 thousand on them an the noise has not returned

Try rotating the rear tires to the front. I have head noise like you describe along with the pulling to one side and it was a bad tire.
