I bought a 99 Passport(Isuzu Rodeo) with 75K on it.  I am noticing a
slight hesitation that
seems to be drivetrain related.  It is almost like something is
engaging and disengaging at the very end of a stop and very beginning
of moving. The best way to describe it is like there is a bowling ball
rolling back an forth in a box.   There is no audible clunk, it is just

something you can feel slightly.   The transmission is not slipping. I
actually had it checked out at a local auto shop, they gave it clear
marks and I asked them to pay attention to the transmission.

Has anyone ever experienced this?

Also, I am noticing what I think is wheel bounce after hitting a bump.
I am guessing that is a shock absorber issue.

One final question, is there any easy way to tell if the timing chain
has been changed?

Thanks for your help.
