Brian, Andrew forwarded me your email.

I responded to check w/ Gforce LOL

I am also out of new INA needle bearings...but I have several sets of good used ones I could ship to Backstreet if you're in a bind.
I will mention it's highly unusual for these to go bad and make any noise. Hopefully whatever 'rebuilder' they used actually put all new bearings in there, and all races. Not just the cones that are in the rebuild kit (I'd guess about 90% of the 'rebuilt' or gear install diffs i have seen the races were not changed out).

Andy didn't have any new in stock, had just used his last set. But he got back to me fast, and offered good used ones to help me out. Seems like a great operation there.

BSP called me this morning, the bearings are definitely shipping from Gforce today, Rich will have them Friday. I should have the car back next week.

I'm checking. Thanks for the heads up.

let me know if this fixes it. ive developed the same sort of noise in mine over the last few months.

i was pretty sure it was coming from the differential im just not ready to plunk down the money to get a new diff.

I emailed Erik from BSP. He confirms all new internal bearings and races. The needle bearings they are replacing are the "outer needle bearings". He says the diff only makes noise if the stubs are in, therefore leading them to believe it's the outer needle bearings.

Doesn't sound like any wheel bearing failure I've heard in my life, plus BSP used a stethoscope on the rack so they would have caught that.

There was another small delay on getting the bearings from Gforce.
Then they showed up yesterday and BSP put the car together fast for me and I brought it home last night.

The 'whaa whaa whaa' sound is gone! Beautiful! Rich said that the internal diff rebuild took some of the noise away, but some was still there. The outer needle bearings got rid of the rest of the noise.

(If someone is on a very tight budget and my description matches the noise they have, and they confirm with stethoscope that the noise is coming from the area of the pumpkin, then you could try replacing just the outer needle bearings first and see where you're at, as the diff doesn't have to be taken apart to do so so its relatively low cost. This is just my personal opinion.)

My total came to just shy of a thousand.

Rich and gang were great to work with.

Being without your GTO for 2 months stinks, it was nice to fire it up this morning!
