I am getting a grinding/crunching noise up front,specially from the left front hub. From searching abit I found:

wheelbearings

hubs

front diff

 

I jacked the car up and there is NO PLAY what so ever in the wheel so that rules out wheelbearings.The sound seems to be coming from the left front so that also makes a busted front diff an unlikly possibibilty. Which leaves the front hub.I checked to make sure its tight,it is, but the nut seems to have backed off a little bit( the pin is still holding it in place, but the nut has bent the pin out a little bit)

 

What is the likelyhood of just tightening the nut extra tight would help fix this?Or are the splines already borked?

 

Also, if they are Borked, will the hub from an 80ish single range 4x4 fit?it has the EA71.

 

car is an 83 or 84 GL wagon.

if the splines are ok, check the cone washer. if it looks chewed, replace it and retorque.

 

when mine did it, it reminded me of a hoarse duck quacking

When you jacked up the car to check for wheel bearing play, did you release the parking brake? The parking brake will hold the wheel solid to the knuckle and you won't be able to feel the bearings.

 

Besides that, there are two bearings (6207-C3 ball bearings). If one was bad and not the other it's unlikely you would feel any play in them anyway.

 

That type of test really isn't valid for EA's - well not till the wheel is about to fall off anyway.

the nut backed off making it a royal pain in the *** to get the pin out. So i tightened it up about 1.5-2 turns more than what it was at. it was very loose.I suppose I could take it for a drive around the block and see if it fixed it...

If the cotter pin was still in it, then the nut didn't turn. What you have there is classic cone-washer/hub destruction. If you don't address this it will return a couple times then you'll just eat the splines inside the hub.

 

Get a new cone-washer and properly torque the nut to 150 Ft/lbs.

instead of speculating about ************, why don't you do it?

 

take the ************ing hub off and inspect it , so that your lazy rump roast does not cause an accident and hurt someone else.
