hey guys,
this is the 2nd liberty the family has bought. we had a leone, still have the never dying 90 GX wagon. and bought a 2.0R gen IV this morning. which is in excellent condition with 85000kms. only issue is when shifting through the gears its a bit stiff. and the clutch is stiff. now im not confusing the stiff changes as the gears crunching or grinding. as they go in without fail and smoothly it just takes a bit more effort than the GX. its due for a gear oil and diff change.

any ideas what it could be.?
and what oils do you guys use?

cheers
mark
