Topic: 6cyl diff & 4cyl diff interchangeable?

[GONZO97]

Okay guys so i have a 91 4runner with 4.10s im pretty sure i need to replace my rear diff beacause i found chunks of metal when changing gear oil, the rear diff is a 6cyl diff. Now my question is , my cousin has a 4cyl diff that hes willing to give me that has 4.10s, is it okay to run the 4cyl diff? or is that not possible?

Im just curious i dont see why you couldnt but then again I dont know too much on this topic either. Thanks guys

Yes its ok, yes it will fit, the only difference is internal parts are different.

so performance wise and everything its completely fine to run it like that?

It will be fine to run it, just keep in mind it is a weaker diff. than the V6.  It it were me, I'd go ahead and run it temporarily while I was getting my V6 fixed and then swap the V6 back in as soon as I could.

x2 If you are just going to dd it in the mean time you should be fine, but it is weaker.

4-10s are 4-10s

4-10s are 4-10s

thats what i figure. Guys run the 4cyl 4.10s day in and day out and they are fine so i dont think itll be too much of a problem. or at least i hope not
