Hey Tim, welcome to HR.com. I can't help with your problem but you should look around and keep bumping this up till you get an answer.

Post your question under the Transmissions-Rearends heading.

You could do a search on this site, too.

Yes, it will be fine, many factory 4x4's are this way as some front diff's are not available with the exact same ratio as the rear diff, like your case of 4.11 and 4.10. I've seen 3.89 and 3.90 or 3.91, 3.07 and 3.08, 4.10 and 4.09, 3.73 and 3.70, 5.13 and 5.14, and more I can't think of at the moment.

If an axle is available with say 4.10 ratio, there is no way to make a 4.11 ratio for it in most cases due to pinion gear and ring gear sizes and tooth counts.

i was told one tenth of a ratio wont make a differants. i bought this truck about two monthes ago and havent even played with it yet. i use to have a 69 c10 with a 350 and loved it but lost it in bad times with the wife. talking about a nice truck. im just hoping my r10 will hold up like the c10 did

that will be perfect, because you want the front end to be a little higher geared, (numerically lower) so when you are driving in snow or mud the front end is pulling you straight
not the rear-end pushing you sideways

X2 on this statement

On icy roads-----equal driving forces on the front and rear can get a bit squirrly (particularly on a truck with Locking/Freewheeling hubs). So---You do want the front going a bit faster.

Full Time GM 4x4 not to worry either----the transfer case acts like a differential.
