Good luck finding 50W gear oil, most auto parts carry 75W & 90W, I found a Lucas product called "Hub Oil", shows a picture of an 18 wheeler on the bottle, does not state the weight, I had NAPA look it up and it is 60W, closest I could find. I was running 90W, but found it to run Hot especially during the 90+ degree summer days with a fair amount of breaking, I think the lower weight runs cooler.
