I have a possibility to buy two diff, front and rear from Landcruiser Series 77 Year ' 95 Pinion gear 4.11, in my country is very difficult find a Solid Axle 8" toy.
So my question is, if the 22R-E is able to move this axles or still looking a Toy 8"solid Axle?

Attached pictures of the differentials

 

Your LC rear axle is not a centered diff. The minitruck transfer case is centered, so it is looking for a centered diff.

No idea on the front. 4.11 will be too tall for anything beyond 31" tires though.

 

and anybody knows about the front solid axle???
because maybe just can buy the front axle for the SAS and change pinion gear

 

The front is slightly narrower but will work.

You will want to regear both the front and rear axles if you plan to run more than 31's, like Red Chili said.

 

can make up the difference in the front with wheel spacers ?

 

I think so.....

Thanks a lot for the info....i think that is better find a solid axle from toy 8", so I still with IFS
