OK so here's my problem, when accelerating a bit harder than normallyfrom a stop while turning left I get a noise in the engine area. The noise is kind of hard to describe butthe best decription I can give is it kinda sounds like a bad CV shaft or a dry/bad bearing. Its not a clunking noise like abad CV shaft though LOL. Ive checked the front diff fluid level, TC level, tranny level, the CV shafts are good and so are the wheel bearings. This problem started after I had 4new tires installed.Could something inside the front diff cause this noise? Torque converter slip? Is it possible for one of the front drive axles to stay locked in, so like 3 wheel drive? Oh yes I almost forgot I have a 2000 4x4 4 dr.

 

It's not a scraping kinda noise is it. It's possible that when the tires were put on that the dust shields behind the rotors got bent and now make a noise when the tires flex in a corner.

 

Just like chevylover said check your dust shields for them being bent!! When I put my 18's on my blaze and lowered it I had a scraping sound in the front, once i checked the dust shields I seen they were bent so I bent them back now its perfectly fine!!

 

same problem i just fixed.

 

Well I just checked for bent dust shields which turned out to be fine, and double checked for bearing slop which are tight. One thing I did notice while taking the wheels off is that the wheels lugs on the passanger side are longer. WTF??? The lugs on the passanger side thread to the very end of the lug nut. While on the drivers side they go a bit more than halfway through the lug nut. Yes I checked to make sure that the wheel is mounted properly. The best way I can really describe the noise is its like a dry universal joint. I went for a drive on a side street where there is no traffic and with the windows down, it seems as though the noise comes from the firewall area.

 

are you sure they aren't bent, mine didnt look bent at all but when I pulled the brake off I could see where the lip on the dust shield was rubbing the inner portion of the rotor (ebrake) mine was a rear tire and it almost sounded like it was coming from the front.

 

Hmmm well tomorrow if its not heavy rain like the forcast calls for I'll check all 4 otherwise itll have to wait till thursday. Thanks for your help guys

 

anytime, keep us updated.

here are my posts on problem I had https://blazerforum.com/m_106518/tm.htm

 

Check for any cables touching or resting on the PCV hose. (accellerator or cruise control cables)

 

Nope nothing resting on the pcv hose, all the throttle cables are hung like they should be.
