ArdWrknTrk Posted June 28, 2021 Share Posted June 28, 2021 I would have thought parts list 185 or 186. Is yours a full floating axle, with flush hubs like that? If so, again my apologies. I'm not any athority on Dana 61 axles Maybe time to decode that BOM Link to comment Share on other sites More sharing options...
Gary Lewis Posted June 28, 2021 Share Posted June 28, 2021 I would have thought parts list 185 or 186. Well, looks like we might need more info. This suggests that there was a change at serial # F10,001. Do we know which it is? It is "after", right? Because it is a bolt and washer. Link to comment Share on other sites More sharing options...

Instead, the snippet below of PL # 185 seems to say it is 355765, but it only takes 4 of them. Is that the right part? What is the size of the bolts in question?

You are highlighting a bolt for the gear carrier in the pumpkin. Link to comment Share on other sites More sharing options...

I'm not any athority on Dana 61 axles Maybe time to decode that BOM I think it is full floating. The only places it touches anything are at the splines where it slides into the center section and the hub flange where it bolts to the hub. Nothing else touches it.

Mine has one nut with a nylon locking ring built into the nut. There is a small metal key that gets driven into the key way and into the nylon portion of the nut to secure it.

Although 7 of them seems an odd number to sell. Anyway, I was wondering what the torque spec is on them and found the following in the factory shop manual. But that doesn't list those bolts, unless I'm missing something. However, on line I'm finding that a 7/16-14 G5 would normally be torqued to 50 lb-ft, and a G8 to 70. So, are they torquing them past that? Link to comment Share on other sites More sharing options...
