Hub temperatures

[ramdough]

Noticed one hub was hotter at 175 degrees F.

What is typical and what is hot enough to need service/debugging?

Rears are hotter than fronts - which is it? Have you done a hub and wheel bearing service? Checked the oil levels in the front hubs and rear differential (and front for that matter)?

Rear intermediate right side.

All fluids were done within last 3-4 years. Probably need to check and top off.

You can typically touch them without significant discomfort - at 175 that's not the case - for most people anything much over 130 degrees is too hot for more than a second or two. Rear's share gear oil with differential so if gear oil was low (besides there being evidence on the ground typically) it should affect both sides. Check it for sure but might be time to disassemble for inspection.

Hub service? Seals, bearing repack, and hub shimming is technically an annual service although in civilian use this can typically be pushed out. I assume if it's been 3-4 years for fluids then it's past due for a complete hub service. Good time to do ECO hubs also.
