I just used a torque wrench for the first time on wheel studs the other day, I retorqued them after a 10 minute drive cause I didn't trust it over my own feel.:hihi:
If you have the same chilton book I do it should be in there, I just did them a few weeks ago. IIRC you're not far off with those 90NM I can check when I get home later but then they're probably done right?
