Today I took my truck to school for the first time in over 3 months (updates coming on build thread) and when I left school I managed to chirp the tires when I took off from a red light (didn't intend too). I initially didn't think anything of it because it was raining and my Firestone Transforce aren't the best but as soon as I pulled into the parking lot at work the truck shuttered and hopped like when its in 4wd so knew the rear didn't unlock. After work I tried going in reverse for a few feet to disengage but didn't help. So when I got home I popped the rear diff cover off just to take a look and wanted to change the fluid anyway but everything looks fine to me nothing surprising. No chunks or foreign matter. Hardly any wear on the gears. I am hoping some fresh 80w90 and some additive will do the trick. My truck is a 1995 Chevy k2500 with 14 bolt full floater 8600lb G80 GT5. Has anyone else ever experienced this? Any tricks I should try before putting it back together?
