Just wanted to let everyone know that Life Like replaced all 4 axles and all 8 wheels on my proto 2000 GP7 after one of the axle gears split.
After a quick phone call they said it was a known problem and replacements would be sent out free of charge. Two days later I had them in hand. I was only expecting the gears, but they send fully assembled wheels and axle gears.
Way to go Life Like!
