Pinion noise?

[JoeOmerta]

What i should've done was measure the preload before taking it apart, then get it back to that number.

But since i don't' have a beam torque wrench anyways, I'll try it out by feel for now. From my research online it seems like I'm too loose so I'll go 1/4 turn at a time until it feels better or i hit where my mark should be.

I'll post an update tomorrow.

Thanks!

Pinion nut wasn't tight enough. I didn't have a beam torque wrench and for some reason no one near by carries them so i did it by feel. When i got under my truck i removed the drive shaft and there was noticeable in/out play in the pinion flange. So i tightened the nut in 1/4ish turn increments until that play went away. At the same time, i checked the looseness/firmness turning the pinion by hand with everything fully assembled. Once the in/out play was entirely gone, it took one more quick tap with my impact gun and i could feel some slight resistance in the pinion.

Took it for a test drive up to 80mph, got on and off the throttle on multiple occasions since and the noise is gone.

Thanks!

@01ssreda4 When replacing the pinion seal, it does not require removing the wheels let alone the axles. Simply lifting the rear end. Maybe you you should do a bit more research.

To each, their own.

Lots of shadetree mechanics do it that way. I dont...i would if i was in a bind but then again Ive built 20 to 30 rear ends so I know what Im doing and what to look/feel for. My point was, you cant get a measurable amount of pinion drag without having the rear disassembled. You might as well mark the nut and go back to the same spot. Suggesting measuring pinion drag with a beam torque wrench with the WHEELS (and everything else) still installed is ******* retarded.

I get it, you've done it this way once, and were successful, or maybe even some mechanic you trusted suggested it to you. That's not a substitute for real knowledge sir, you're just repeating some BS you heard.

Nice. Good to hear!
