I committed the worst offense to my tractor. I let the neighbor borrow it for a couple of days. Yes, I'm an idiot. That aside, I now have to repair the damage, 2003 or 2004 L3130 GST. It's fine while in 2WD mode. BUT, in 4wd mode, the left front wheel hub area had a pretty bad squeak when turning back and forth. I pulled the front hub apart and checked out the bearings and such, and it all seems to be OK from my inexperienced eye anyway. Anyone else ever had such an issue and can throw me some insight?
