I just replaced my trailer (10K) brakes and while I was at it I did the bearings as well since they had some age on them. First let me say I have done bearings on NEW axles before but not replacement on long time USED axles. I followed all the specs as per usual on the bearings but I always worry about the brake adjustment with new drum brakes.
I took it out for a test drive of about 2 miles and using my IR heat gun checked the hub temps after a mild brake burnishing. All were within a degree or so and less than 100 degrees.
I then took it out on the highway for about 10 miles at 55-60 mph and then came back via back roads. When I got back the right side hubs were 125 and 109 degrees and the left side hubs were 101 degrees.
Not exactly an overheat but an interesting difference. Thought about sun angle but it was equal in exposure for heating. Jacked up the two sides (independently) and the wheels would lock with the same amount of brake controller force thus the brakes are adjusted the same.
I am getting ready for a 500 mile trip with a full load and do not want to run into an issue. I have never looked at hub temp differential as closely as this before even though I do check hub temps every time I stop at a rest area but only to check that they are not overheating.
Is there any reason to suspect that I have an issue with my new bearings or is this differential normally seen?
