9.5SF Swap

I didn't pay attention to what axle he is working with, but if it is an 05-06 Escalade AXN axle, those do have a tone ring sensor at the very outer end of the axle housing. I posted a picture of it in this thread, when I acquired mine. It is still uninstalled here, as I am dealing with other higher priority issues unfortunately on the 6.0.

REAR END UPGRADES

Any inexpensive ones in your area? I'll probably keep up the search for an 05-06 one anyway, since I believe these were all 3.73 gear ratio, and that matches the gear ratio in my 04 Tahoe Z71 4wd so I won't have to re-gear to match the front diff.

Another bit of info I recently found on the NBS 2wd escalades that came with the elusive AXN 14bolt 9.5sf. Looks like they only offered the AXN in 2005 and 2006. According to LKQ it was not offered in 2004 or before so that narrows down some searching for anyone interested.

Also, It looks like they only came with 3.73s which is good because the NNBS AXN only came with 3.42s best I can tell. I haven't been able to identify if the NBS AXN comes with a G80 or other clutch style posi but here are some RPO sheets of AXN equipped NBSs maybe someone can decode them better than I. I know G80 is for the grenade locker but I do not remember what the code for the factory posi is, can't imagine they put a big axle in a 2wd and left it open.

Were you ever able to find out if any of the GMT800 AXN axles come with a G80 or other traction device from the factory? I have been trying to find that out also. So far, every one I have seen in person was an open carrier. I posted a request on an Escalade forum for 2wd 6.0 Escalade owners to report back if their RPO list has any G80 or some other traction device, but that hasn't received any replies back so far.

The factory Eaton posi that came in the Trailblazer SS, which also had a unique AXN axle, had an RPO code of G86. I did acquire a TBSS rear axle from a local yard, believe it or not, and I bought it only to harvest the G86 Eaton posi out of it and then selling off the remains. I have not run across any other factory posi or locker RPO codes thus far.

Oops, forgot the Traction Control of the GMT800s. None of mine had it.

Found it on rockauto, axle repair bearing. TIMKEN TRP59047 I think. Probably will just let it ride with the old ones since I’ve hammered in the outer axle bearings at this point.
