Clutch or other issues? baja 5t

[ocrsqr]

baja 5t had a shimmy, where the car wouldn't roll, rear tires were rocking back n forth, maybe a clutch or spur gear?? rolled the car and gave it alittle throttle and ran perfect, never happened again?
any ideals?

Sounds a bit odd but not sure with such a vague description. I'm sure its the best you can do kinda like telling the car dealer a problem. You know rattle, rattle, thunder clatter, boom, boom, boom...

that sounds like a broken cross pin or something in the tranny or drive cups/bones. could be pinion bolt too.
