Axle Swap Thread Along With Info.

[74CustomK20]

Well I bought a set of axles to upgrade mine, a Dana 44 big bore hub front end, and a full floater 14 bolt rear end. Hooray!! This is the 2nd set I bought, after getting burned on the first. Well lesson learned, you get what you pay for.

Anyway. I pulled the cover and there is some rust, oil buildup around the magnet, but bearinga looked alright... I will update in daylight with pics. Guess this is just a little intro to get things started!

Day 2. Tires are off as are u-bolts and driveshaft out. Also got the 14 bolt on stands to work on easier... so productive I guess. Won't touch it tomorrow, gonna be with my son... but how can I decode the numbers on the ring gear? Tried to search but didn't get much...

41/11 is 3.73 or 41/10 is 4.10. It has both a 10 and 11 stamped. Mark the pinion and count the teeth for a positive identification.

I tried that today but it's hard to see the pinion gear... plus I was distracted by the little one today. 2 weeks old and already lost my 9/16th wrench...

I think that 10 41 is your gear teeth/ratio; 4.10's

[74CustomK20]

I have a matching Dana 44 front so they'll match... just 4.10 would be better as I have 40's... if not guess I'll just regear!!

[74CustomK20]

That's what I thought. The 10 41 being 4.10'a and the 11 75 being November of 1975... manufacturing date...

Update as luck and all would have it... cleaned the difference cover and all up, then resealed and put back on. Looked good just a little rust on the cover and stuff so hope it's all good. Going to put it in later today or tomorrow and see what happens...
