sierra hub nut torque
femster87 - 13/9/10 at 07:47 AM

noticed in the haynes manual the torque on the upright is rated to be between 310 -350nm. My bench cant take that. but i think its hell of a lot of torque. is this what everyone has used?

That's correct. Best done in-situ using the weight of the vehicle to hold them still.

Are you doing them up or undoing them on the bench?

Search for recent posts by "coozer" with a tip for doing it off the vehicle.

Fit and tighten on the bench then put the full torque on once fitted to the car

its a big torque, but thats the preload the bearings need to work properly...

My Haynes manual for rear hub nuts states: 250/290Nm or185/214lbf ft.......i used to have a aircraft torque wrench with 12ft handle,used to torque propellars....well you wouldnt want them to come off would you?

if haynes are wrong then so are autodata and ford

the sierra bearing might come in 4 bits, but they arn't the same as the older adjustable ones....
