Gentlemen
About 2 years ago my M1009 had the flex plate come apart, it tore off at the center leaving the center still bolted to the crank, but the rest of the flex plate (FP) was completely disengaged from the center.
Fortunately it still ran and started, but I knew this was NOT a good thing! I bought a replacement FP from then Checkers, now O'Rielly auto parts, I installed it, and all was well, I drove it for abou 6-8 months until I went through a series of electrical issues that kept her inoporable for almost 10 months.
So about a month and a half ago I finally got the electrics sorted out and drove it for about 2 weeks when one morning when going down the off ramp, it started screaming/howling, but when I accelerated it would get quiet until it got to speed then it would start screaming again.
Having gone through this several years ago, I was "pretty sure" it was the flex plate, either that, or I ran my transfercase out of oil! (Don't ask!)
Well this morning I pulled the torque converter pan, and sure enough the flex plate was broken just like it did the first time, all the way around the crank shaft.
WHAT IN THE WORLD!!??
At first I thought it might be due to a sub-standard after market flex plate, probably made in Mexico or China. I saw the post on NOS GM flex plates and I WILL buy one of those for this project.
However, I read anoither article on SS where it was stated a broken motor/tranmission mount might cause the FP to break, then a friend told me the Crank could be moving back and forth, but I find that hard to believe as the engine would probably bind up if this was happening and I'd have excessive oil leaking.
So I was wondering if any of you have encountered this issue with the FP, and was it something other than a sub-standard FP that was causing the issue?
I hate to go thru all the work of installing the FP to have it do the same thing in 6 months or so....if there is some other issues I should investigate, I'd like to know what they are.
I will look at the engine/trans mounts I'd like to find polyurathene replacements if anybody knows where to get them from. please let me know.
THANKS in advance!
