If you find yourself chasing cross when you scale is one way to tell. Meaning washers are the same but your readings are different.How often are you replacing spindles and why ? Also looking for replacements for phenom. I would assume that some would say that spindles get fatigued or "flexed out". If so how would you tell ?
You can get a couple of seasons out of the spindle bearings and kingpin bolts, but as our regular season maintenance, we replace all the bearings/ kingpin bolts and chain every season, keep the old for emergency replacements.I figured those should be replaced on some sort of schedule. Bushing and bearing wear is something I deal with daily. Machinist for air force. You would be amazed how fast an A10 can wear out bearings bolts and bushings
