Re: Dana Super 70 Limited Slip Issues

Well we have a resolution. Dana is sending me a new diff. The tech at ECGS had me send him photos and he said that it would be pretty tough to screw up the spider gears. I explained to him that I had cut down one shaft and he was totally understanding of that and agreed not an uncommon thing. No issue putting a 70hd carrier in a Super 70 housing. Thank you everyone for your input, it was much appreciated. I will definitely be using ECGS in the future, they stand by their product and their customer support was fantastic. They had a new tracking number sent to me before I even forwarded the rest of the photos to them.

Here are some photos of it disassembled for those interested:

He didn’t. He thinks it’s possible that there was a bad spider gear maybe dropped or something. He said he’s never had to warranty one of these before.

Re: Dana Super 70 Limited Slip Issues

If you get another dry one, separate the case and soak the clutches in the modifier for at least overnight.
