The hockey picks are alot more rigid and take more vibrationApparently, my eyesight is not good .... The CV joint on my truck is no where near little, and my vibration has started 3 years after owning this truck. I will try the mounts first, and then the major mod if this does not fix the issue. I am running this truck as a commercial vehicle, and have to worry about DOT!
I did find that in the Technical Manuals for this truck (TM 9-2320-273-24P) , call for the LORD mount of CB1009-9. Could not find anything on-line or at the surplus websites. Talking with AM General, the FSCM number is the same thing as the Cage Code. When you look up Cage Code and the numerical number following it, the manufacturer of that part number is known. AM General cannot give out data or dimensions on any part to civilians, even on obsolete parts. Talked with LORD, numerous times, and they do not have the data on this mount. They are calling it an obsolete part. LORD finally came up with a substitute of CB-1125-12. This is CB1125-12, per the Military, with a NSN of 5325-01-086-3949, which is the Part Number for the M915A1 mid mounts. These are still available, and this is for anyone's information.
I agree wit WillWagner, LORD was not willing to help much, and wanted me to provide the measurements, to them, for the CB1009-9, which should be in THEIR data sheets.
Snap a picture of your jackshaft since there are prototype trucks from Northrop grumman that are different builds than the common RRAD done
