stub axle rebuild question

[ezzzzzzz]

I'm calling on those gone before me. I assembled my 240Z rear stub axles today. All new parts from Nissan were used. The seals were pressed in until they seated as shown in the FSM.The only difference was I used the 280Z stub axles and companion flanges. The housings were marked "B" and I reused the "B" distance pieces that were not deformed or crushed. I ran down the nuts with my impact (about 500 b/ft) which I know exceeded the factory torque spec. I could disassemble and install new distance pieces and retorque if I need to. When I rotate the stub axles there is no noise but they have moderate rolling resistance. I don't suspect any problems but wanted to hear from anyone who has done this and experienced the same thing.

 

NOTE: I loosened and retightened the nut to about 200-250 lb/ft and the rolling resistance hasn't changed.

Having accomplished this about twenty times over the years, it sounds like you are OK. New bearings are pre-lubed by the manufacturer and they can be “tightâ€. Also, most beginners tend to “over pack†the stub axle cavity with grease and when you tighten the stub axle retaining nut the excess grease can result in increased rotational resistance.

 

Things will loosen up after a few miles on the road. Don’t worry about it.

Thanks for the input. I thought all was okay but wanted a little reasurance. I only pack the bearings well and not fill the cavity with wasted grease. It's easier to address problems now than once it's all back together under the car.

Are you checking the "resistance" with just the stub axle alone in place. I thought the same thing of mine, however, once you have the rotor and wheel assembly in place, mine spin more freely thanks to the added weight of those components.

Yeah, I was turning the stub axle alone. Not much leverage to work with there.
