So I just recently found out my rear spider gears are worn out. Someone said it’s about to blow up my R/P whether tomorrow or another 10,000 miles. I was saving up for new wheels and tires. Was going to upgrade from 35 -38. Tires are at 8/32 now but need to replace soon. What would be more important to replace? Tires? Upgrade rear diff to Truetrac now since gears worn. I’m already at 4.88.
