8.8" vs 8" locking rear diff

They should have just put a Dana 60 in it so we would not need to worry about it breaking and being overloaded so easy.....

 

Just a heads up since it's a rear diff thread. Well just changed my rear diff fluid, and as suspected I was low. About half a quart low, maybe even more. Replaced with redline 75w85 synthetic. I can already feel the truck shifts smoother. I have the off-road so my diff takes 4 qts. Which it took exactly that before fluid started to trickle out. WTF Toyota

 

The 8.75" diff is the same diff that the Hilux has come equipped with for the past several years. The locker is similar to an Eaton electronic locker just a electromagnet that pulls the side gears into a locked position. There is defiantly a difference in the gear size from the 8" & 8.4" when compared to the 8.75". I have had hands on both of them...
Oh man The fun things you get to play with when you work over seas for a decade and your wife is from a country where they still market the real Toyotas.

 

So, do you know if the actuator is the same as the old problematic 8" e-locker actuator, or is this a different/superior design?

 

24% boost in gross axle weight rating!

 

It's not similar in any way.

Old thread, but it’s a relative question.

What are the differences in the housings between the 8.0 and the 8.75?

 

Just think, .5 quart of fluid × 20,000 trucks sold per month....... That's a lot $$$$$$$$$ saved.

 

The 8.7.5 is bigger than the 8.0 and has 2 additional bolts

 

What exactly is bigger about it? You said there are 2 additional bolts I assume that attach the 3rd member in to the housing?

 

What are you trying to do ? Identify what you have or trying to debate the difference between the two. What’s up ? Everything’s bigger on the 8.7 versus the 8.0. ring gear diameter is bigger , the pinion diameter is bigger , the carriers bigger, the housing has to be bigger to fit it , third member carriers bigger , the bolts holding in the carrier are larger and there’s more of them.

 

I’m not here to debate anything. Really just wanted to know if there was a difference in housing sizes. You answered my question. It’s literally nothing deeper than that. Lol.

I’m building a diff skid for a third gen a buddy of mine owns. I own a 2nd gen. Now I know I can’t mock it up using my truck and I’ll need an 8.75 rear end to work with.

 

you know what's not bigger, the carrier bearings!!!

 

Why wouldnt you mock it up on his truck then...

 

He's 2 hours away.
