Different Gear Ratios in Axles

Ok, I am having a bit of a problem idk if its gearing or weight displacement issues..

It snowed a bit back and i went to put it in 4wd high so i could get home on the back streets slowly.. bad idea.. i was fish tailing the whole way home and it was like the back end wanted to kick out because the front end was going too slow..

I did not buy or install the gears or do i know if any where installed...

i Bought sand bags today... a little late in the season but i still threw them in i dont know if it made a difference because all the roads are plowed now..

Does this sound like a gearing issue or not enough weight in the rear end? Also can i check the gear ratio without popping off the diff covers?

Honestly in 4wd my back end fish tailing dramatically reduces because the front helps pull. Either you are going too fast or your 4wd isn't engaging properly

Hey I have a question and dont know where to ask it.
I have a 93 YJ 4/10 gears, open diff. Dana 35
I also have a 90 XJ with 4/56 gears and a spool dana 35
the XJ is going to be 16 yr olds DD, spool is not so bueno on the highway.
So, can i switch the spool to the YJ or does the different gear ratios hinder that idea?

You can swap the gears on them as your going to need to a gear setup anyway. Also I wouldn't trust a spool in a D35. The gears must be the same front and rear if you ever want to use 4wd.

The problem you described may not have anything to do with gears, it could be there is a difference in tire size or even a significant difference in wear between one or both front versus one or more back tires. If you engage 4WD in this situation, the tires can turn at different rates on soft surfaces. Several years ago I had a Cherokee Limited 4 X 4 with Goodyear tires. I had a problem with the front tires and took it to Goodyear for replacement. They installed the replacement tires and I did not check them assuming they knew what they were doing. About a week later I engaged 4H on a rain slicked road (fortunately I wasn't going very fast and there was no traffic) and the Cherokee did a 360 in the middle of the road. I checked the new tires and discovered Goodyear installed different sized tires than were on the back tires. When I asked them about why they put different sized tires on, they said their book said they were equivalent, and they would probably have worked on a a 2 WD but not a 4WD.

And of course, with no history, the gear ratios could be different.
