anyone use Auburn's diff repair service? Options

[CamaroFS34]

I have a couple of old diffs laying around, and I remember hearing about Auburn's DREX program. The problem is that they ask for a receipt or other proof of purchase, and most of the diffs I've bought came from someone who had an F-body and bought it originally from SLP (as a takeout).

I was wondering if anyone here had used the DREX program before, and if so, how much of a sticking point the receipt might be? I thought the diffs were stamped with a build date or build code anyway. Or do you think they are just trying to prevent people from getting diffs from a junkyard and selling them for more than the $75 it cost to have Auburn repair them?

Thanks for any insight.

Karen,

The .pdf brochure on the Auburn web sit lists the criteria for a rebuild candidate.

Point 1 - "...the unit must have been purchased within the last 4 years. This can be determined from your original dated receipt, OR by the date code stamped on the differential case..."

Looks like you may be in luck, if you're within 4 years. Their web site has a description on how to read the date code. They do say that unless you have a dated receipt, they will only accept the diffs for rebuild within 4 years of manufacture as determined by the date code. I read that to mean if you have a receipt as the original purchaser, the time allowance may be longer.

I have an old Auburn sitting around here. I should give it a look over.

I had the optional Auburn unit from SLP in my '02 SS. After wearing it out, I heard about this program.

I sent it in, in early January. Haven't heard from them since.

They did not ask about a receipt. They just asked for the markings on the unit itself.

Cool. The original brochure I saw (a year or so ago) said the receipt was necessary too. The build code is good to know. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif)
