Rear whine & pinion angle?

[turbov6joe]

What's the source of the whine coming from the rear that most TTA's have? I remember hearing/reading something something about a bearing(s) that tend to whine after time...I need details/specifics please.
Lastly, what do you all run for a rear angle?...currently I run -2*.

TIA

Is it a howl that happens when you decel? Or is it a constant whine.

The howl comes from tweaking the ring gear. Whine would be bearings.. pinion bearings.

Would you like some cheese with that Whine :biggrin:

Seems to come and go at certain speeds on both accel and decell.

That's what I thought.

Razor in this post you said the howl would come at decel? Have you ever heard one howl really loud under light acceleration? Thanks

Joe, You should be running 0° on the street. Running the -2° will knock out the seal, bearing and cause gear wear. When the pinion is too deep into the ring it will cause a whine which will get louder with speed increase. The -2° is for launching not driving.
