OK gurus, I've got a funny one...
'08 STX YD25, manual, 4x4, d/c, 90,000kms.
I noticed something the other day on the highway.
When I lift off the throttle to coast a little and then add throttle to accelerate, there's a subtle "bump" in the driveline.
I can feel it thru the seat. There's not really any sound, just feels like driveline free-play take-up.
It's subtle, but persistent.
Seems worse in a higher gear at lower RPM, than a lower gear and higher RPM. (which might mean greater difference in tailshaft/engine/wheel speeds)
I haven't had a chance to check anything yet (too busy with work) but I'm thinking tailshaft unis or dual mass flywheel...?
Maybe engine or g/b mounts?
Diff backlash?
Anyone found or fixed similar?
