Jerry Posted October 28, 2011 Posted October 28, 2011 Hi all :wrench: As title, my rear diff is getting warm after highway driving with no load on. Not hot, just pleasantly warm to touch. Is that normal? I've never noticed it get warm before unless I'm hauling, which I'd expect, but I've had a wheel bearing replaced recently so I'm keeping an eye on things down there. The new bearing was just a little tight after it was installed but the guy who did it said that was normal to allow for bedding in. Sound right? I thought so but wanted to check the forum wisdom. TIA :thumbsup:
ParadiseMJ Posted October 29, 2011 Posted October 29, 2011 I think I'd want it "pleasantly warm". Lotsa stuff going on in there what with the meshing of gears and xx amount of RPM's...it's got to be warm.. They make aluminum diff covers with ribs to dissipate the heat...but just warm is to be expected with any machine.
reece146 Posted October 29, 2011 Posted October 29, 2011 Normal. The harder it is working the hotter it will get (within reason). Cruising at 120-140 km/h gets mine quite hot. Aero drag is a huge load. Off-road does not.
