<< but the link could be either the Thrust Arm or Torque Strut>>

..Could be..
but if you read my post. you will see that the original thrust links
were weak and have been modified..so that is why it is recommended they be replaced with the modifies part before
changing all/any of the other links..
plus the ease and $$$$ factor makes sense to start here...
A good look at all components is in order, but these [if original] should be change any which way..with a good chance of solving the problem/s.......
