I got a 2006 vision cxn613 with a ac-460 and lately my oil temp is way higher than normal(normaly at 190 F loaded and now it goes up to 225 F loaded) but coolant Temp is still normal. I'm running rotella 15w40 and did a oil&filter change and still having problem.

Before I get into buying and changing the oil coolant I would like to here a second opinion.

Right on switching cross member it will be.

Thanks,best

I have a 2006 mack vision air suspension 40k rear diff. and when I'm going up a steep hill loaded my U-join(in front of front axle) rubbs on the crosmember I tried to move the leveling rod up, even drill a hole to set it higher, change the leveling rod control valve still nothing. But the other day my governor had a little mal function and I was running 150 psi and it quit rubbing until I fix the governor....any idee?
