Torque value discrepancy in repair manual

[1995 993]

I've searched with no results; I apologize if this has been covered:
I'm reading the repair manual (thanks bcameron59) and found some differing torque specs for the front A-arm and caster eccentric and mounting bolt.

Volume 4 of the repair manual section 40 "Tightening torques for front axle" indicates:
"Joint Carrier to A-Arm Caster Eccentric" 65Nm/48 ft. lb.
"Mounting" 120Nm/88 ft.lb.
"A-Arm front bolt to side member" 110Nm/81 ft. lb.

A few pages later under "Dismantling and assembling suspension" indicates:
#24b "Joint Carrier to A-Arm Caster Eccentric" 80Nm/59 ft. lb.
#24a "Mounting" 140Nm/103 ft.lb.
#20 "A-Arm front bolt to side member" 105Nm/77 ft. lb.

Is there an explanation for the differences? Should I use the higher or lower value or split the difference? Does it matter?

I've had this post up on the other forum for a few days with no results. I'm hoping someone here can answer.

Thanks for reading,

I would check what bolt size, grade and thread you are dealing with and use those specs to look up generic torques. Then go with the number that's closer to the generic torque spec. Good news is that the numbers you quote are pretty close together already!

Thanks aigel, that make sense. I'm surprised with all the suspension DIY's that this hasn't come up before.
