thump on left side of rs venture tf, slow speeds

[pinksen21]

this started happening recently as i go slow speeds between 15-40km/hr. Going forward once every revolution there is a thump where my left foot sits in foot holder. It only happens at low speeds, its not the belt i have changed it to see if that was it. Only feels it on the left side only. Ive inspected the track and the track is in good condition, the tunnel is in good condition, Everything seems normal..

Did you use a new belt? Had a similar experience with an 05! turned out to be the belt! Also driver alignment?

I not a belt, my next guess is the left driveshaft bearing

Yes that is what someone else told me, apparently because there is no grease nipple and they fail at 10000km. Im at 8500km. I have checked everything else and nothing. So that seems to be prob. A new belt is on her, and i switched to another new belt and then i even used a belt that i had around that had 2500km on it and still got the same prob. At this point im leaning towards bearing. thanks though

I know this thread is a bit old, but I was having this same problem on my Apex, and just found out my set screws to lock the bearing to the driveshaft were gone. I put in a new set with locktite and no more clunking noise.
