Ball joints on 50″ wide with 2″ lift

Good day all,

I have a RZR 800 with only 1,700km (1,100 miles) and only had the lift kit for approx 300 miles. My 2 lower front ball joints are shot.

Any of you by experience would know if this is normal wear?

If this is caused by the lift, how often should I be expecting to replace those?

Thanks,

JerryCanada
