so if its whining you need a new ring and pinion? Can you still drive it w/ the t-case whine and it wont cause any damage to the car?

 

I am about to get a used whining tcase that I'm gonna get rebuilt by Shep. Needs a ring and pinion. Should I get a stage 1 or 2 rebuild? As far as lsd's go quaife is the best one to get but is Helical good as well?

 

It should be ok until it grenades. You also have a chance of locking up all 4 wheels.

 

Stage 1 does not come with LSD, only stage 2 and 3. Personally I've had no problems with the helical stage 3. I dont think a stage three is needed unless your making tons of hp.

 

How can I tell if the whine I'm hearing is my t-case or my walbro? The noise is pretty faint, sometimes I can't hear it at all. It sounds nothing like the "death whine" people are showing in their videos. When I do hear it, it has to be under 3K rpms on accel or cruise, or the exhaust will drowned it out/it goes away.

 

the walbro will make noise in neutral.

pretty sure my ring and pinion is going bad. But i only hear mine from like 58mph to 64mph with throttle applied. In the video you can hear my tcase for just a split second its like the sound has a on/off switch.

What do you guys think

 

What are the chances that the drive shaft is bad? A dealer told my friend that he needs a new t case and drive shaft.

 

Yours seems to be ok. But, since it is whining at cruising speeds, that is a sign its on its way to death whine. I beleive you should only be able to hear the whine at low speeds and at cruising speeds it should not be audible.

 

The transfer case in our 03 is also bad .. makes a horrible noise .. haha

 

the whine you hear at low speeds is a straight cut 1st gear.
