After consulting this forum about attaching new pedals to my bike, I read that white lithium grease would need to be applied to stop the pedal threads from ceasing. I did just that and a few months later discovered that one of my new bike pedals somehow came lose and ate away at the crankarm thread so badly that nothing would repair it (I had to ride it wobbling out since I was miles away from my destination). I waited a half a year for someone to sell the same crankarm on ebay because the crankset was practically brand new and I wasn't going to pay another 150 for a new one. I just attached the new crankarm with the grease a week ago and today I noticed my crankarm was wobbling off too! I'm tightening these parts as damn hard as I can and I can bench 200+ easily. What gives? Is it really just more tightening that's required or is the grease causing this (I use a lot btw - the white grease is visible around the threads)
