Synthetic gear oil for wet front wheel bearing?

Is it recommended to change the gear oil in the front wheel bearing reservoirs every so often? If so, should I change it to synthetic gear oil?

Lonne,
I checked a couple of chassis and owner's manuals and saw no requirement or schedule for draining / replacing the front hub gear oil. That said, I'd recommend going to synthetic due to its higher temperature specs.

I had considered converting to synthetic fluid from non-synthetic fluid but was told the bearings would have to torqued/adjusted since the bearings were 18 years old and the synthetic fluid is thinner than non-synthetic fluid.
Any truth to this or other concerns when going from standard to synthetic fluid in the oil bath hubs?

There has been talk over the years about synthetic oils causing ball and roller type bearings to slide or skid rather than roll. I have run it in high performance car rear ends without any problems. It probably wouldn’t hurt to run it, but there is probably no real benefit to it. These wheel bearings run at a low rpm because of the large diameter of the tires.

I switched mine over to synthetic several years ago and everything has worked great the 20K I have driven since.
