Hello room - Just opened up my 10 bolt Camaro differential and found one of the axle c-clips had fallen out - how is this possible if the pinion shaft is supposed to hold the axles tight against the gears? is there something I should check as far as wear or misalignment? - This r/end has been out of the car for some time - but never upside down. Also where can I buy/find a pinion yoke holding tool so I can remove the pinion shaft? -I live in the San Diego area. Many Thanks - Charlyg
