SuiteSuccess Posted December 26, 2018 Report Share Posted December 26, 2018 14 hours ago, Bigtrailer said: Be aware guys, in a used truck that has run over the road, these balancers sweat, and will clump inside the ring, and will be a blob inside the ring. Found this out after all 10 of mine I removed and tried to spin them in my arms. Some didn't move, a couple sounded like a golf ball was inside. I took them off after experiencing a vibration I thought was a u-joint or the power divider. I put in bags and all my vibration left. Just to prove this, go down to a commercial tire repair dealer and ask him. Better yet, let him hand you some from his scrap pile and you try it for yourself. They work great when new..... but up the road...….! By the way, I was running these in my small fleet..... took every one off! What do you mean by “sweat”? The moly beads are suspended in oil media. Would think for them to clump, the oil would somehow have to leak out or thicken with heat which I would think the engineers considered. Usually oils thin with increase temp rather than thicken. Without a pinhole leak or such, I’m just not seeing the metal ring channel as being permeable.

Av8r3400 Posted December 26, 2018 Author Report Share Posted December 26, 2018 I just got a set for the drivers from Santa. The rings are filled with oil. I can see where if the ring is punctured and the oil released, they will be less than useless. I'll be ordering the fronts shortly. I need new front tires for this year...

Guy just swapped them to his new truck. I would think if a set was going to clump up. His should have done it way before 2 million miles. Mine are going on 9 years old, not that many miles. But I would think sitting would cause this issue faster. Will never run a truck again without them. Link to comment Share on other sites More sharing options...
