I have a truck out on the road with a bad rear differential. I was wondering if I can pull the rear drive shaft and rear axles and just run it on the front differential to get the truck home. Obviously use something to cover the hubs so I don’t loose fluid.

Are you sure the rear diff is bad? And not the front diff?
Being the front diff is the main diff, and is used the most. -
No it’s definitely
-
That is a myth that one diff is used more than the other. They pull equal.

It can be any one of the 4 wheels on a tandem application. People always thing it's the rear diff that drives.
It's what ever tire has the least amount of traction that is going to spin. Could be left,right,front or back. You actually have 3 differentials in a tandem setup with a power divider.Troy_, snowman_w900, SAR and 5 others Thank this. -
And when it’s spinning, it’s actually spinning 4 times faster than normal.AModelCat, KVB, Oxbow and 1 other person Thank this.
