Got a change a rear wheel bearing

[happy]

Was wondering on torque specs for axel nut and hub bolts?? thanks!!

don't they sell the whole hub/bearing assemlby as a copmlete unit?
I think it comes off of the upright by unplugging the ABS sensor and undoing four bolts

It is a unitized hub/bearing assembly. But the axle nut has to be removed/ retorqued as part of the replacement procedure.

Well, I replaced all my hubs at the beginning of this season. I 'torqued' the mounting bolts and the axle nuts like I do on every other car/truck.
Pretty freakin' tight on the mounting bolts. (hard to get a torque wrench in some of those spots on some cars, Viper included)
1/2" Impact gun on the axle nut. -tight, but not to the point that the new hub/bearing is ruined.
Lots of guys will say they frown on this approach, but this is kinda how it's done.

Well, I've read posts by Viper tech that the torque of the axle nut should be 250 ft-lbs which correlates with a couple of other vehicles I own that use a similar Timken assembly. The original spec in the Viper manual is lower and apparently was not enough to accommodate the kind of forces that some Vipers see. The tech also said that the racers often use an even higher torque value. However, the "whatever" torque approach may well be good enough also. I wouldn't argue with success.

Ok sounds good

No intended implication that these are not 'critical fasteners' that require proper torque values.
But when there is limited accessablity to use a torque wrench without a bunch of extensions and wobble drives........
you do the best you can evenly by feel from many years of experience. My elbow 'clicks' at the appropriate torque on fasteners like that.

250 ish is probably good for the axle nut.
Again, years of experience with air tools, and changing CV axles on various makes and models day in and day out,.....one becomes proficient at what 'feels right'. An in-experienced idiot can ruin stuff real quick.
Not advocating a 'whatever attitude' by any means.
