94 Explorer Limited Auto 4x4

Every time I turn right,2 HI, fast or slow, my left front tire squeals. Pressure is good on all 4 corners. No irregular treadwear or anything like that. I'm wondering if it's an auto hub thing. Hubs don't feel like they're engaged (But I'm switching to manual hubs ASAP so I know for sure if they're locked in or not)

Anybody have any ideas?

 

If you are in 2 wheel drive the 4x4 hubs have nothing to do with it - they are not engaged and thus have no influence on tire speed. This sounds like an alignment issue or you're just driving too fast. But the radius arm bushing wear out and it tweaks the alignment of the wheel, usually fairly severly. You should check out all your bushings and replace eveything tht is worn and then go down to the alignment shop. The passenger side radius arm bushings are covered with a little metal shield to "protect" from heat of the CAT. So you can't see the back end bush without disassmbly. You can see from the front side and compare it to the drivers side to see if it is still centered or not. Of cours if both are worn you can't tell without disassembling.
