I've been planning on getting a rear locker for the last few weeks and I have narrowed my selection to the Powertrax No-Slip. The only problem I have is I'm having a problem figuring out which one I need.

I have a '93 4Runner w/ the 3.0 so my rear diff is an 8", 4 pinion.

The only problem is, the only part number I can find is for:
- a pre-95 Toyota
- 8" ring gear
- Open 2-pinion
- 30 spline

Here's a link to the item.

Can anybody help me out with this? Is this the right no-slip? and if not do they make one for the V6?

Thanks,
Nic

 

As far as I know, only Lock-Rite makes a lunchbox locker for our 4 pinion diffs. Your other option is to swap "down" to the 4 cylinder diff. The 4 pinions make it super strong, but also leave very little room for the locker guys to get their parts to fit. I read that Lock-Rite has the patient on getting it all in there.

I was waiting for an Aussie Locker, but they've been 4 weeks now "We're working on it"

 

hmm I may just find one of the 4-cyl diffs somewhere and buy a no-slip for it.

What are the limitation on the 2-pinion anyway, compared with the 4-pinion?

 

Just space! With a cross, instead of a single pin, there's less room to set up the mechanisms.

 

Aussie has been working on the V6 locker now for about 2 years that I know of...

 

Retrofit a 4 cyl diff and get an Aussie. They're good.

 

I've spent a good amount of time looking for other options besdies
the Lock-rite, and have come to the conclusion that it would just be easier
to go that route. I personally would never want to downgrade any part
of my truck, let alone the rear end.

 

Unless you're running big tires with, with extra low gears, and high horsepower, you're going to have a problem. I don't think the diff is the weak link anyways.

 

I'm pretty set on the no-slip, but retrofitting a 4-cyl diff is most likely the way I'm going to go.

I don't really consider it a downgrade, just a different option from Toyota. The 4-cyls are just as reliable as the v6's from what I've read.

I'm sure something else will break before the diff anyway

Yeah, I'm not a hardcore enthusiast at this point. Maybe I will be, maybe I won't


And on another note: anybody know where I can get a 4-cyl diff online? Used preferably, there aren't a lot of pick'n'pulls in my area, would be easier if I could find one online.

Thanks,
Nic

 

First find out what ratio you have, then keep an eye out on this forum or your local TTORA.com chapter. Shipping is going to be expensive though. Best find a pick and pull.

 

I have also considered the option of swapping in a 4cylinder diff so I can go with aussie rather than Lock-rite.

While I am in a junkyard is there a simple way to identify the gear ratios on the 4cylinder trucks I crawl under so I know whether or not I should pull that diff?

And do you just pull the diff off or do you have to grab the whole rear assembly axles axle shafts all that?

Thanks

 

[QUOTE=Noltz;50804412]Just space! With a cross, instead of a single pin, there's less room to set up the mechanisms.[/QUOT

no not just space. the bearings are bigger in the v6 thirds.

and the housing for the 4cyl is a lil weaker.

 

That's what I was looking for, thanks. But is that a big enough difference in strength to keep my V6 third for just recreational offroad?

 

There was a thread I read a couple days ago. If you jack up the rear end and spin one wheel exactly two revolutions and count how many times the driveshaft spins you get the gear ratio. ex: a little over 4 is 4.10, 4 1/2 is 4.56, a little less than 5 is 4.88, etc.

And for removing the diff, you just unbolt it from the driveshaft and the axle and run off with it pretty much.

If people start stealing diffs...

 

no you would be fine! 4cyl R&P and v6 R&P are the same. and thats what will break. the housings almost never break. and the bigger bearings are nice but nothing to worry about. you would be fine!

 

all you need is the diff.

search pinion paint! different colors for different ratios.

 

As mentioned, the spinning tire method is the best and most effective way to find out the ratio of the diff. I usually recomend spinning the tire 20 times then dividing the amount of pinion rotations by 10.

To remove the third:

-Unbolt driveshaft
-undo e-brake
-unbolt brake lines
-unbolt the backing plate bolts (4 on each side)
-slide out axle shafts
-*remove ABS speed sensor if truck is equipped with one, best to unclip it from the harness (near the gas tank) since 95% of the time pulling them out from the third causes them to snap*
- unbolt third

Be carefull, the third is pretty heavy and it can be akward to hold.

 

Jay, whats this about the ABS sensor? Do you need to pull that before removing the third?

 

UPDATE: I had sent an email to powertrax and this is what i got back:

"Thank you for your interest in the Aussie Locker. The V6 differential
is a 4 pinion design, and our XD20830 is for the earlier model 2 pinion
carriers. We have developed a new V6 Aussie Locker and it is currently
in the July production schedule. Currently we are estimating that if
there are no manufacturing or external issues, we will see this new
model in the USA inventory in early August."

I am hoping this works out, i want to get one of these.

 

I was sent the same e-mail, but it said "30 days", and that was 3 months ago. I ain't holding my breath.

What is the consensus on the LockRight, is it garbage? They're pretty well regarded from people that own them, but they're not Toyotas. I really don't want to try and track down a 4cyl diff when I just put in a rebuilt regeared 6cyl diff.
