Outer Limits 4x4 Board

Hi guys
sounds like ive spun a bearing in my gearbox, has anybody seen a rebuild kit to suit, or should i be looking for a recon?
we are pretty mechanically minded so a rebuild is not too much for us, just looking for hints and part numbers?
Thanks

I've had the same thing a couple of times. First time I had it rebuilt. That lasted about 4 years before crapping itself again, so I sourced a replacement box and swapped it out. The replacement had a dud tranny case, so I swapped mine onto the new box and all has been good ever since.
