Question about 1994 Chevrolet Astro

1994 Chevy Astro has two distinct noises. AT 40

1994 Chevy Astro has two distinct noises. AT 40 mph sounds like the carrier bearing is making a loud humming sound. At Upper 40's this sound lessens then over 50 mph there is a sound coming from both rear wheels, but is louder on the passenger side. Could it be the rear bearings? What can be done?

Hey First thing I always look for is cheapest thing to repair or look at .. Make sure your tires are not cupping .. or make sure they are wearing good and smoothe all the way around .. this can make a terrible noise if they are cupped or worn improperly.. then I would Jack up one side and shake the rear wheels make sure those bearings are tight feeling .. you should be able to tell if they are loose this way ... I dont know how many miles are on your van but usually the drive line is not the problem.. this is probably last thing you need need to shake and see if there is play in it.. Holler if you need more and thanks Jerry

What is the part number for a carrier bearing on 1995 chevy camaro


(a little late in responding - but maybe someone will need this info).

If you mean the carrier bearing on the driveshaft - then you must have a v6 model. I would advise to skip replacing it and instead purchase a 1pc shaft (no carrier bearing). The cb is located near a Hi-Speed CV Joint which make changing the carrier a little difficult.
A new replacement 1pc driveshaft costs about $225.00
The carrier bearing itself may run $40-$140. ( http://www.fortwayneclutch.com/index.php/driveshaft-parts/carrier-support-bearings/gm/1993-2002-chevy-camaro-v6-pontiac-firebird-v6-carrier-bearing-new-f-body-carrier-bearing-for-v6-models-pn-s-3r80-40.html ) - for reference...
You could also check a junk yard for a 1pc oem shaft (most shafts there are bent or have bad uj's and will cost $$ to have fixed )
>1994-2002 f-body models all have the same length from the seal of the transmission to the center of the uj @ the diff.
>when looking for an oem 1pc shaft you will find them in Steel and Aluminum. Slight differences in length when measuring center to center of the universal joints ( 40 7/8" - 40 1/2" ) - but the slip yokes vary in length, weighted / non-weighted..etc = this will make it appear the the shafts are different.
>>watch out for oem shafts with the weighted slip yoke from manual 6spd v8 models. This slip yoke may hit the trans/exhaust mount that is used on v6 models.!!

My 2004 montecarlo gets a loud vibration noise that sounds like comming from dash but cannot hear noise from outside but is so loud that i cant hear the radio with the windows up and does it only driv


This may sound radical, but while driving on an open road with no traffic, put the car in neutral and turn the motor off. If the sound goes away, the problem is in the motor or trans. If the problem persists, its probably a wheel bearing or something stuck in your wheel. Car will restart in neutral, and just drop it back into drive.

Back driver side wheel is making a loud pounding noise when van is in motion 1997 chevy astro van


run your hand across the tire tread itself and check to see if the tread is feathered or cupped. this will cause road noise. Also could be a wheel bearing worn.

There is a loud noise at 45mph.


Find a quiet empty stretch of road. Go 50 mph, put the trans in NEUTRAL and shut the engine. If noise is still there, swing car left and right to detect noise differences. Could be hub or axle bearings. Not engine or trans if noise is still there. Hope this helps
