Front axle roar

captivahach · #1 (**permalink**) 12-16-2010, 05:22 PM

Ok so I got to use 4wd for the first time above 20mph. Its only in 4wd doesn't do it in 2wd with hubs locked in. Does it some on accleration but really bad on decel. Its a really loud roar and can feel it some in the floor board. mostly from the diff side. I toke the hub off and checked the bearings they seemed to be in good shape. So i regreased them and still there. Is it in the axle

The easiest hing you can do is to check the oil. If is IS the diff you'll have to pull the cover and take a look.

If Locked in 2WD is quite (where all the U-Joints and Hubs are spinning) I'm afraid I'd be suspecting, because it makes drastic changes with load, it could be inside there

I think I'm in the same boat... just started to notice it, someone has to know something!

sounds to me like possibly bad pinion bearing especialy if it changes with load conditions.
check diff fluid and condition silver is bad!!

I hope this help you i fixed my problem after taking the cover off the pumpkin to inspect and finding nothing i decided to remove the front shaft because i was out ideas. At the velocity joint by the tranfer case al joints were good except for the ball in the center of the two, this is not able to be detected unless u remove the shaft and move the joint by hand. Took it two Sadlers driveline shop to be repaired and now drives like normal. Even though the joint looks to be in good order take it apart and feel for stiff movement.

I'm having the same problem. Are you talking the u-joint by the t-case? Or are you talking about the slip-joint in the front drive shaft?

the CV joint at the T-case end. Just went through this same process with my bro's truck.
