I'm in the middle of a trip that i drove 5 hours from pensacola to jacksonville FL and when i got here, my car started making this popping/clunking noise when the tranny was under an initial load(mainly starting in first or when I let off the gas and give it gas again). I thought it would have been a U-Joint so I took it in to a local tranny shop and they told me it was coming from my differential. They wanted to charge me 200 bucks to crack the cover open and inspect it.
I had my 3.73 installed about a year ago. I also bought an install kit consisting of new bearings and such. My question is: What in there could cause this noise? Is it major? Should i be worried driving 5 hours back home and bringing it to the guy who did the work for me?

Thanks for the help.

$200 to inspect? That's how much it cost me to install my gears at a friggin ford dealership. Do you know if the guy who installed your gears put the additive in when he did the change?If not, your spiders could be screwed.

Actually,the Friction Modifier additive is used for the clutches in the carrier, NOT the spider gears.

To answer your question Trick98GT.You could have a bad bearing. Either on the pinion, or a carrier side bearing. Reguardless, I'd get that looked at A.S.A.P. before you cause any more damage.

No. A friction modifier was not used as far as i know. I brought him the gear, 75w-90 redline synthetic oil, and the install kit.
New bearings were installed when the gear was installed...I dont see how they could go bad this quickly.

Regardless, I would take it and have it looked at before making a long trip, unless you like walking. I would add some friction modifier too.
