I own a 95 camaro 3.4 ltr. I hear humming from my rear axel as im driving down the road.. what could it be???

Question

ive already checked the breaks, the shoes are still good, and the drums dont need to be serviced, im thinking the bearingings, but hoping that i just may need to check and/or add some greese into the axel, if thats the case, does anyone know how to check that??

Answer 1

put gear oil in it !!! before the rear end goes on u,lol or the pinion bearins gone. maybe the crown???

Answer 2

I will start with a warning: NEVER let Goldwing12795g work on your car. There has never been a front drive Camaro. Rear differential bearing and gears on Camaros have a long and evil history of failing. They are complete junk and GM spent millions replacing them under warranty in the eighties and early nineties. There is a fill-plug located on the center portion of the diff. Remove it and see if any fluid comes out, if not add lubricant (available at any Autozone) until full, (level with fill hole). You may get lucky but most likley if lube level was low enough to make gears & bearings whine then the damage has already been done. The assy will have to be overhauled, appx $750.00 if gears are O.K. Don't feel bad, you are in good company with thousands of other Chevy owners that have been through similar headache.

Answer 3

Don't forget to check the tire pressure and tire tread pattern. The rear end filler plug is located at the right rear upper on the front side of the banjo gear housing and after being removed, the fluid level can be be checked using your index finger. Add #90 rear end gear lube as needed.

Answer 4

On level surface, you should be able look at the back of the rear housing and see a small plug, that unscrews like your oil pan drain plug. If you take that off, you should be able to feel in with your finger and feel gear lube. If not, add some 90 weight lube. If it does not stay up to level, you probably have bad bearings. You mentioned good drums so I do not think you have bearing problems.

Answer 5

Could be slightly out of l ine. Are you noticing any change in handling? You may havehad the car dropped while getting it serviced. If there's hum theres probably friction which means soemthign is gettign worn down, fix ASAP. And I dont mean to insult you, but make sure it's just not something in the trunk or a cosmetic attachment. Try calling 'Car talk' if theyre still on the air too - out of boston, used to be on NPR.

Answer 6

Check the grease in the rear end. Unscrew that little bolt head and stick your pinky in to check level. Sounds a little low.

Answer 7

Two reasons:
1. Lack of gear oil
2. broken oil seal or bearing
Its too messy doing all this repair, if you can afford to send it to the authorized service center, the better. You can get a genuine parts, if required.

Answer 8

Since your car is a frount wheel drive it has to be a rear wheel hub bearing.
Take off the wheel and the drum
Now spin the hub. Does it spin easy? dOES IT SPIN A LITTLE THEN STOP?
tRY TO WIGGLE THE HUB SIDE TO SIDE AND YUP AND DOWN< IS THERE A LOT OF PLAY? dOES IT WIGGLE? iF IT DOWS IN ANY OF THESE TEST IT IS GOING. yOU CANT PUT GREESE IN OT OR REPAIR IT, JUST REMOVE THE PEARINGS AND REPACK THEM. If these bearings are no repackable just replace the hub

Answer 9

i'm no longer highway legal suitable now. nonetheless could desire to bypass to all those colleges, and for what? i could no longer even arise with the money for gasoline yet I do merely like the occasional taxi. as long as you're in a taxi the driving force will preserve you.

Answer 10

your humming sound is a worn out axel bearing and must be replaced immediatly or it will leave you on the side of the road.

Answer 11

It sounds like the bearings I had the same problem with my 96'
Ford explorer but don't Take my word for it
