So we plan on hitting Yellowstone in a few weeks and it will be our first trip over a couple hundred miles. I've probably done about 1000 miles on the trailer so far. This trip will probably be around 1800 or so miles with max 8 hours of driving between stops.
My question is around axle bearings and the grease marks on my wheels in the below image. I thought it was only on one wheel, but it looks like there's a bit on each wheel and after taking this picture i cleaned the rim and the streaks were back, albeit in smaller amounts.
I've read up on how the Lippert folks sometimes overfill and bust out seals in the rear. Is that what's happening here? I pulled the cap off and they all appear to be very clean on the inside, i.e. the nipple is clear and i could see grease around the spindle?.
I doubt i'm going to have time to take it into a dealership to get looked at...
Do i just bring a grease gun with me and occasionally fill? What temps should i expect on the hubs and where should i use my thermal gun to test?
Any and all help is greatly appreciated.
