Chevy, mmm, I LOVE my dad's 97 Silverado. The seats are infinitly more comfortable than mine and the quality of workmanship is better also. I bet the new Chevys arent as good as the old though
Rear ujoint, messed up front ujoint (he said).
I dont think his Jeep had a positract system, it would be lockers all around (if I understand you right). He could still drive on the front wheels, but it made a nasty sound.
