2WD Rotor Install Question
Looking at the 2WD rotor selections on RockAuto, I see that some brands (Durago) instruct you to torque to 295 lb/ft, turn the rotor counterclockwise 5 times, and recheck the torque, or failure may occur. Is this critical to all brands or just Duragos? What is the 5 turns doing? Have you ever heard this procedure required of other brands?

I saw this, but I can't imagine it does much other than ensuring the hub spins and check for tightness. I just got close to the 295 and buttoned everything up. No issues in the subsequent 62k miles.
Note, I'm not recommending this approach, just what I did. Manufacturers don't just make up torque specs just for fun, but many are just CYA on their part.

My torque wrench only went up to 250 so that’s what I torqued mine to... I didn’t spin anything either. I guess that’s to ensure the rotor isn’t binding up or rubbing something?

295 is to ensure that the preload on the bearing is set properly. This torque spec is important for bearing life, but not so much for safety IMO. I bought the Tekton 3/4" tq wrench just for this job...

Make sure you have a long pipe to help with torquing it. I'm not sure how its possible for someone to torque it down that much, even with a 300ft-lbs wrench, unless you are super strong or weigh a lot.

Well, Bosch rotors replaced with warrantied units. Old Wagner TQ Semi-Metallics still had lots of material left, but I installed new Wagner TQ ceramics. Now lets see how long these bearings last.
