When I spin while backing up i hear a clunking noise. Anyone know what this might be? It seems to be coming from the rear end, The machine is still going through the break in period.
Everything else seems to be fine except for this noise.

 

hey northern,
i would like to understand more about when it happens, and under what situations. i have always gotten wheel bounce when i nut it in reverce. this makes a slight clunking noise. also, when i first put it in reverse, i also can get a slight clunking noise. i would think it might be the rear suspencion extending do to the romping on the throttle. when it extends all the way, it would make a small klunking noise too.
sorry i could not help more, but i am sure its nothing.
good luck.

It's kind of hard for me to explain righ now since I'm just going through the break in process. It kind of sounds like it is coming from my rear drive train. I noticed it when I would gas it a little while backing up on ice and the rear tires would spin then catch something. I don't recall it happening when going forward.
Thanks for any and all help
