Sharps the front hubs are held on by thee bolts not by the axle. With the axles and the drive line out the front diff will not move. This should be safe to do.

 

i said wheel bearings, as in the bearings being held into the hubs correctly, as i said i am not 100% on it, but i do remember reading about it somewhere just seems like a bad idea to tempt fate IMO, just fix it right and be done with it.

 

thanks dear shrpshtr and thanks Mr. dolittle for the feedback , I agree that the bolts are held with no axle after i checked it than by my eyes but thanks a lot for reminding me to check out.

today , i will complete this job and let you know by tomorrow if things go smoothly...hopefully.

 

woow , great guys, i have removed the driveshaft and placed the car on 4HI and it goes fine , the car is moving and all that loud sound is gone , i just realized that when i start accelerating till speed of 40 or 50 the car become more powerful and light , somebody told me that the AWD is connected always till the speed of 40 mph but after that it disconnects automatically.....dont know if this is right......

thanks to all of you and to this wonderful dodge forum.

best regards,

awd is always connected no cut off speed, 4hi is not supposed to be used above 40 (when the system is completely installed) as it will cause excessive strain on the transfer case.

 

what do you mean please, is what i have done wrong , cuz the car runs in 4HI but without the driveshaft that connects the front and rear differentials. the car runs nomrally, i don't think the 4wd is working in this case but the gears are moving as normal.

please explain more ..

dear sharpstr , the system is not completely installed in my car since the driveshaft is not installed, is it still applied to me (i mean the use of 4HI with speed above 40mph)?

thanks

 

wordsworth, no need for double post so im merging them for you

also you are fine to drive at any speed as while the front driveshaft is disconnected you will not damage any thing because the damage is caused by the front and rear driveshafts spinning at different speeds going around corners.

 

Yep, the awd setting allows the binding to be released by the front and rear turning at different rates. 4HI does not but 4HI has more traction off-road in slippery situations were bind isn't an issue.

 

thanks shrpshtr for your help - and thanks adukart for the info...

guys , guess what, i discovered that the differential is not damaged and the probelm is with the driveshaft where it's ***** and seal are damaged clearly......i come out with this conclusion for some reasons: first, the driveshaft has no more greace in one end and the rubber is not there and the ***** are making loud sound. also, when i removed the driveshaft , the noise is gone which means the differential is fine as the axles are not removed yet.

the reasons i didn't check the driveshaft in the first place because it was replaced 2 years ago, i never imagine that it could be the cause......aaaaah i feel tired now because i have done all the dignosing myself....but finally, i got the problem..... although i went to lots of mechanics and they were 100% it's the differential...

thanks all

That is an incorrect analogy.


Yes the base of the wheel bearing on a 4X4 is connected to the spindle via 3 bolts, however the wheel bearing is a 2 piece bearing set up. See the end of the CV Half Shaft inputs into the bearing through the center, then you have a main nut on the outside end. This main hub nut then presses the second and primary bearings together giving the wheel bearing pre-load and ensuring against it's separation. The rear end of the bearing is connected to the spindle. So you are incorrect in your analogy.
