Diff ratio's
Some people think that using a 4.1:1 with 4.11:1 will work. Short term 2wd use not a problem but 4wd use will dramatically shorten the life of a transfer case.Transfer case wind up even with the same diff ratio's has exploded more than one transfer.Ever noticed how hard it is to go back to 2wd after driving in circles or on hard surfaces you have to go in reverse to get out of H4.

have you posted this just to see who thinks you're an idiot?
the path/rotational difference between 4.10 and 4.11111 differentials is about 0.27% (1/369), which is less than the path difference front/rear generated by driving around 20 metre radius turn, or even driving on lightly undulating ground. it makes NO difference in 2WD as you only use one diff anyway, and the difference is 4WD is negligible as 4WD should only be engaged on surfaces where the wheels have opportunity to slip. 80 series GXL full time 4WD transfer cases have a centre differential eliminating the possibility of ANY transfer windup.
there are 4WD manufactured with geater differences in front/rear differential ratios, anything up to around 2 percent will not be noticable or effect transfer case life or off road performance.
