Although prior answers are indeed correct, the lubricant question is mere pedantry for any fastener that is not critically torqued.
Head bolts (ARP and otherwise) are an obvious exception, but as such these are usually provided with a special lubricant, or clearly stated as a lubricated torque with something like 30W motor oil.
There is no way any chassis component on your Jeep requires critical torquing. Whatever overtorque results from lubrication and torquing to a dry specification can be ignored. You are not going to come anywhere near the elasticity of a Grade 8 fastener. This is not a TTY (torque-to-yield) application.
My feeling is a 25% undertorque might result in improper clamping force, which is far more serious an issue that the "overtorque" resulting from lubrication. That number is far too high anyway, as even a "dry" specification assumes CLEAN and dry.
It's along the same lines as the shadetree parable of never using anti-sieze on wheel studs - 'cuz your wheels will fall off...
To further be a stick-in-the mud, when was the last time you had your torque wrench calibrated? I'm guilty of such things myself. That SnapOn your father bequeathed to you may be a beauty, but I have little doubt that the average torque wrench with some age, and which was sometimes put away under tension, can vary by 10-20% all by itself.
