How often do others have to change out their tag axle bushings? I have a fleet of 9 quad axle dump trucks and it seems as though they go through them more often than the past. I’ve gone through using multiple brands like Atro, Automann and Hendrickson and there’s not much of a difference for durability on them. Seems kind of random when they get worn out. I’m trying the W&C brand next, apparently they’re supposed to be good quality and not very expensive.
On highway about 500,000 plus miles, or till find slack at bushings. But those get raised in parking lot situations. Dumps on the other hand I see used off highway?
