Blazers in park = rattling noise ..... Blazers in drive = whining sound & while driving on interstate (ranging 35mph-65mph) I can feel it hesitate when I press on gas almost as if it can't (but it doe) go any faster & sometimes it sounds as if it's in park & pressing gas pedal over & over...... Periodically you feel something jerking while driving on interstate (does this when you don't hear the sound as if I'm in park pressing on gas pedal .... Last couple all problems have escalted .... Today when I was going onto exit off interstate it jerked couple times (jerky feeling when your car is out of gas & it's getting ready to die...ONLY HAPPENED TO ME ONCE !!) my daughter even felt it & asked what was wrong. Overall, whining sound is louder & now rattles loudly & jerky is now severe.... HELP!! ..... No one has ever been able to answer this one ... My check engine light is always on (told it was computer malfunction that it's fine) but periodically a ABS light appreas & stays on couple days & goes away...

Have you had the catalytic converter checked. When they break apart they will make a rattle ling noise. eventually the broken pieces will plug the exhaust and cause a lack of power feeling. When the exhaust is cold hit the bottom of the catalytic converter with your hand. If it rattles it is bad and needs to be replaced.

2003 Mitsubishi Outlander Grating Noise, Front Struts?


It very well could be the strut.
smaller chance could be the CV axle.
Also have the splash guards/heat shields checked to make sure they are all tight in place.

My 2000 blazer lt it seems that when you try to drive it trys to go into 4x4 part way it squeals and makes ticking noise it also feels like the brakes are on any idea what is causing this


The only thing that I can think of is your blazers 4x4 silinoid. If the silinoid is going out it could possibly cause the problems you are describing. I hope this helps you out, and if you have any other questions please feel free to ask.

I have a 1999 Chevy Blazer 4dr with 4x4 recently I have noticed that when I accelerate there is a loud rattling coming from th underside of my truck, it also happens while I'm at a stop, and still in...


It could be the catalytic converter. While vehicle is off and parking brake on, go under the vehicle while it is cool and tap on the exhaust. See if the noise doesnt sound the same as you tap where the exhaust goes into the bigger section by the transmission.

Strange raddling noise from front passenger side


if the noise only happens when the vehicle is in motion...check the front suspension. place the jack under lower control arm ,then get a bar and lift up on the tire..ball joint issues are well known in blazers and cause this condition. if it does the rattle noise when its idling and to op temp--could be the cat converter causing the noise on pass side directly under passenger seat. when cold, smack the cat with rubber mallet and if any rattle is present, cat should be replaced so it dont cause further damage .hope that was helpful !!
