Hub temps wonky.

[LukePrinsloo]

So I just towed my boat home for the first time.
It's a 2011 AR240, front axle is 100F, rear is 151F. Same on both sides. The original tires were warn way more in the back ( I put new tires on before heading home thanks to this forum. Discount tire matched Goodyear Endurance D1 205/75r14's down to match the carlisle radial HD price...).

On the highway at 65/70 mph i felt a good bumping/vibration. The rotors were in the 240 degree range.
Could this mean the brakes are staying activated when I am moving down the road?

The rear bearing buddies are popping outward from the hub center.

Sounds like your brakes are hanging up. They probably need to be taken apart, the rust cleaned off all parts, lubricated and reinstalled. Even if your brakes are in perfect work order, those hubs will be a little higher in temp than non-brake hubs because disc brakes always drag a little.

Lock out the brakes and run the same test... One could be dragging!

I had similar symtoms last year. Bearing buddy popping out, losing the cap and slinging grease all over the rim and tire. Diagnosis was a frozen/stuck caliper. I ordered a new caliper and replaced it. Good since.



A c-clamp could not compress the piston.
