I guess it's my turn to ask for help from the resident mechanics. My 2001 Blazer has a vibration coming from the front drivers side. It goes away when I turn to the right, it will also go away for the split second the weight is lifted off the front after hitting a rise. Any ideas on what it could be? |

Quoted: Quoted: My first thought is wheel bearing, do you know of anyway I could check to see if that is the source? I don't think it's a cv joint, it doesn't pop when turning like they sometimes do.Wheel Bearing? CV joint? Not a mechanic, but you just pull the hub out to dislodge the bearing, replace and see if the vibrations goes away.....assuming this is a 2wd and not a 4wd. |

Does this complicate things much? |

Does this complicate things much?Go buy a Chilton Manual, there should be step by step instructions on how to check and repack/replace the bearings. Assuming you are mechanically inclined. |

Jack up that wheel off the ground. Spin it and listen closely. Hear grinding? Grip it at 12 and 6 oclock and shake hard. watch for movement in the ball joints. |

Does it get progressively louder the faster you go? Then it is probably the wheel hub assembly. a common problem on Jimmy/Blazer. Also possible ball joint since the noise goes away when you turn? Common 2001 Blazer/GMC problems: Transmission air/check valve Electronic 4wd switch wheel hubs ball joints belt tensioner failure and the shitty mileage. A 5300 Vortec V8 gets better mileage than this 4.3 V6 |

my half-assed, "worth what you paid for it" internet guess is wheel hub assembly then. If you are a do-it-yourself kinda guy, check and compare prices at rockauto.com on the parts. A few other common problems I forgot to mention are the ABS module, and the gas gauge flopping all over the place when it gets under a half tank. |

My gas gauge doesn't even work.  |

My gas gauge doesn't even work. I guess I should've said common OTHER problems  If your gas gauge doesnt work, you fit right in to the 2001 suck club. Sending unit is in the gas tank. Another six beer job.  |
