Re: Dana 30 gear noise
That is the idea Peter. It can take up to 500 ft lb to set that sucker
according to the book I have. I was always told to go at least to 300,
but as mentioned, I have never done one.

Re: Dana 30 gear noise
Hmm. A conundrum has surfaced. I've incrementally increased the torque on
the pinion nut a few times to the maximum of 250 ft-lbs my torque wrench
will do. The preload has increased, i can feel more resistance to turning,
but I can still turn the pinion nut with my in-lbs torque wrench set to it's
minimum of 25 in-lbs without it clicking.
What do I do? Crank on the pinion nut with a breaker bar and hope I don't go
to far, or put it all back together and hope the preload is enough as-is?

Re: Dana 30 gear noise
Hmm. A conundrum has surfaced. I've incrementally increased the torque on
the pinion nut a few times to the maximum of 250 ft-lbs my torque wrench
will do. The preload has increased, i can feel more resistance to turning,
but I can still turn the pinion nut with my in-lbs torque wrench set to it's
minimum of 25 in-lbs without it clicking.
What do I do? Crank on the pinion nut with a breaker bar and hope I don't go
to far, or put it all back together and hope the preload is enough as-is?

Re: Dana 30 gear noise
Hmm. A conundrum has surfaced. I've incrementally increased the torque on
the pinion nut a few times to the maximum of 250 ft-lbs my torque wrench
will do. The preload has increased, i can feel more resistance to turning,
but I can still turn the pinion nut with my in-lbs torque wrench set to it's
minimum of 25 in-lbs without it clicking.
What do I do? Crank on the pinion nut with a breaker bar and hope I don't go
to far, or put it all back together and hope the preload is enough as-is?

Re: Dana 30 gear noise
Hmm. A conundrum has surfaced. I've incrementally increased the torque on
the pinion nut a few times to the maximum of 250 ft-lbs my torque wrench
will do. The preload has increased, i can feel more resistance to turning,
but I can still turn the pinion nut with my in-lbs torque wrench set to it's
minimum of 25 in-lbs without it clicking.
What do I do? Crank on the pinion nut with a breaker bar and hope I don't go
to far, or put it all back together and hope the preload is enough as-is?
