AC 7040 duals make popping sound

[Jack Boedigheimer]

AC 7040 with on axle duals. The left side makes a popping noise on right turns. Have checked the bolts and all seem tight, the wheel is new as the center broke out of the old one. Any ideas what else I should check to find the problem ?

Thank you

Don't know how your duals are made, but if the bolts grab the rim with wedges, check for slippage/wear on the wedge where it contacts the rim. Check for shiny spots showing that the wedges are sliding on the rim.

Not an axle bearing is it? sometimes sound travel through steel making it hard to figure out where the sound is coming from.

Might try raising up the back end, & spinning both sides by hand. You will also be able to shake the wheels around (at least without calcium in them) a little bit. If nothing; then try taking the outer wheel off, & try everthing. Turning tight with / without brakes. Running on the side of a steep slope both directions. That would help determine an axle / bearing problem. Thats at least a start!
