Hey all. My dad's 07 T660 Turbo had a horrible grinding sound down in the reverse/brake area. Can anyone tell me what that might be? I've been thinkin' about a couple different things. But I don't know.

If the chain is loose the sled would most likely be jerking as well. Sounds like it could be a bad bearing or possibly worn brake pads? Checks shafts for bearing play.

one of my friends had a problem with a t 660. he cracked one of the gears in the chaincase. so check the gears and chain.
