Loud knocking sound from front drive axle side

It sounds like the driver front axle or some gears are stripped, someone told me it may be the "spider" gears!

    i think my son ran in a ditch and it started about that time, when you give it the gas ,it sounds like a loud knocking,,stripped gear sound coming from the front drive axle area,and it's worse when you turn

  • brianskyler Sep 12, 2009

    it does this under acceleration ,around corners,just going across the lawn if going straight or turning,worse when turning and very ruff and loud like grinding when accelerating faster. it was my 17 yr old son and when he told me about it it was to bad to drive.i think it may be something like the front drive assembly stripped . does that sound possibly to you.

    does is get worse when you turn? did it just start out of no-where? or over time?

  • 97-KMAG May 11, 2010

    Some more information is needed before someone can actually tell what the problem may be. 1.) Does it only do this on corners? Under acceleration? Driving Straight? 2.) When you say...."sounds like the driver front axle or some gears are stripped...." what does that sound like to you - please try to be as descriptive as possible and use analagies if neccessary. 3.) If it's a 4wd vehicle, does your 4wd work or have you tried it lately? 4.) Has this gotten progressively worse or did it just "Happen" one day? Once you can answer these, please re-submit this problem and I'll be glad to help. Thanks, Kevin

I really doubt that its the spider gears that are bad. Most likely that its the axle shaft- not as bad as it sounds- I sell lots of them.

You can also try pulling the vacuum line,off of the switch on top of the transfer case and see if the noise goes away,sometimes they leak internally and partially engage the front axle and that will give you a gear grinding noise out of the front end,i have replaced alot of them for that reason,hope this helps.its easier to get to from the drivers side

How do I replace my inner axle on the passenger side of my 2002 Dodge Ram 4x4 4.7L. I lent my truck out and the C clip let go of the CV axle. The intermediate axle spline is stripped and I need to change...


Lift and support front end on suitable jack stands preferably on frame. Remove right front cv axle, stub shaft, and seal. You will need to pull the right front brake caliper assembly loose and place to the side. Then remove bolts from shock and upper control arm and hub nut to do this. Next, remove axle lock actuator on passenger side of front axle. Place a drain pan underneath front diff cover and remove cover and drain axle. In the center of differential there will be an 8 mm head bolt holding spider gear cross-shaft. Remove bolt and cross-shaft only! Push inner axle in until clip clears inside of passenger spider gear. Set clip aside and push/pull axle shaft straight out to passenger side.

1994 geo prizm replaced drive axle and wheel bearings and it sounds like the drver side axle is binding or broken or not in all the way it makes a loud knocking from the driverside like the axle is hitting...


I see there are two different axles listed, with and without abs. One is slightly longer than the other. You could have the wrong axle or it could be something inside the transmission. I doubt the passenger side axle would affect the driver side.
Can you raise the front end and make the noise with the car parked ?

Front axle not fully engaging and makes really loud noise when this happens which in turn ruins a gear in front axle have replaced cable, gear and now am being told vacuum switch transfer case needs...


Its sounds **** you are haveing a problem with the vacuum actuator that moves the gear in and out of 4 wheel drive mode. Its located under the battery tray. You need to remove the battery and the tray then its easy to serivce its a diaifram and if it isn't holding vacuum eighter its bad or you have some kind of a vacuum leak leading to it If you can fix it now your gear should be ok just don't let this go to long it could lead to some expensive repairs It cuuld also be the vacuum actuator at the transfer case but this sounds like you are haveing someone do this work for you. Iwould ask them why they didn't fix the problem correctly in the first place thats what you pay them for and it sure sounds like they misdiagnosed the problem in the first place

I selected part time 4wd on my 1996 jeep cherokee sport. Seconds after engaging I heard a loud noise from the front left hand side of the car and now I'm not able to de-select part time 4wd to any other...


sounds like you have a broken c/v joint or differential up front. Likely the joint. Have someone look under there to see what's not moving or what is, without driving the front wheel. If it's the joint, you can easily replace it. A complete used axle from a scrapyard or a rebuilt one from a parts house is relatively easy to replace if you have a half decent set of tools and a decent manual such as chilton or haynes. Only part they may not mention is that you need to hold the axle centered as it goes into the gear set...If you don't it will knock the inner seal out and cause a leak.
If you need further help, just ask!!

CV cplaced still clicking


seeing as it is a 4wd and you replaced all the problem areas( this wont cost you anything but 75W90 x 2 Quarts and RTV) take all but the top diff cover bolt out of the front of your jeep let all the fluid drain then take off the top, sift thru your gear oil that came out with a magnet and see what you collect. if not much visually inspect your carrier and spider gears and your gear and pinion. I can almost gaurantee your problem will be in either the spiders or your gear
