Hi all, This winter i broke an axle in my driveway (not sliding, just decided it was done with life). After the shop replaced it, I also converted from the auto hubs to warm manuals myself. I have noticed a problem though, in 2wd, with the hubs locked, i hear a grinding/ clicking noise from even a slow speed, and it also shows up when coasting or engine braking in 4x4 with the hubs locked. This behavior was never seen before this winter. Any ideas what may be going on?

I just want to get the order straight: shop replaced front axle, no issues with noise or grinding. Then you replaced the auto hubs with manual locking hubs, and the clicking grinding noise started. Is that correct? If it is, I would take off the hubs and do a visual check, because if you have a grinding noise, you might be able to identify where. Good luck.

The hubs are working and I know they are not the source of the noise, and when the Xcase is in 4H/4L the front wheels get power forward and reverse and the 4x4 otherwise operates as expected.
The clicking comes when coasting or engine braking above about 35mph, or at any speed when the Xcase is in 2H but the hubs are left locked.

I replaced the hubs because they were not always engaging properly. Later today I can try to post a video of it clicking.

Shouldn't manual hubs be unlocked when you're not in 4? Try unlocking them

Does the noise go away in 2wd , when unlocked?

Yes, the noise goes away when I am in 2wd with the hubs unlocked.

This is a video of the noise that happens when I coast at about 35 mph with the front hubs locked and the Xcase in 4H

it is more prominent in the second half of the video.


The sound that happens in 2wd with the hubs locked is similar
