folks, this happens intermittently especially when i'm rough with the gearchange (especially the lower gears) or when i let try to accelerate in a high gear.

what is the symptom for:
1. wear in engine mounting?
2. wear in rear pittman (dogbone) arms?
3. wear in center bearing (prop shaft)

i have already changed the plastic bushing for the gearlever pivot and also the plastic white spline bushing near the center prop shaft coupling.

another issue i have is vagueness in selecting 3rd. or 5th gear - the horizontal travel plane feels a bit loose. again this is intermittent and happens when i downshift from 5th. to neutral when i cruise to a stop. thereafter selecting 5th. usually involves an effort to push similar to the reverse detent effort.
