[QUOTE="MalcolmV8, post: 15218555, member: 8854"] Can't say what it is for sure but wow broke this lower in less than 1k miles. A new record for me. The new motor with high compression is so snappy and responsive. The RPMs wrap up so fast and quick when you blip the throttle it makes a stock terminator motor seem very lazy and lethargic. Perhaps that extra snap accelerated this problem. The other big change is I put the lower together with a stiffer than stock bushing material because the 2.9 would normally crush the stock rubbers flat and have some wobble and slop in the lower. Maybe that contributed. Snapped the tri-bar right off the shaft. Engine was still running but nothing was spinning. With engine off you can see what I mean here [video=youtube;fQHjfeG7BcU]https://www.youtube.com/watch?v=fQHjfeG7BcU[/video] The tri bar on the left of this pic is the one I just snapped. Notice it ripped the threaded part right off. (the one on the right btw has stripped out threads from a prior incident lol) [IMG]https://lh3.googleusercontent.com/-vzkDQGXRDz8/VtUthmiuTEI/AAAAAAAAGts/T_wWsf94_Ek/s640-Ic42/IMG_7214.JPG[/IMG] So the shaft is stuck in there because of the snapped off threaded piece. [IMG]https://lh3.googleusercontent.com/-qxYjDH4p34c/VtUtjOd8cxI/AAAAAAAAGts/YtWuV6YV1P0/s640-Ic42/IMG_7217.JPG[/IMG] [IMG]https://lh3.googleusercontent.com/-I9ZPHhIN2Og/VtUtiaOFvnI/AAAAAAAAGts/rUCGAxNu2lI/s640-Ic42/IMG_7215.JPG[/IMG] That center shaft was so seized into the damper I was really stuck for a while.
