Ok here goes

I have brought a lokka diff for my d21 and have run into a problem

I set it up so its with in the specs that its meant to be but it still wont unlock via bench test.

Took it to the diff shop and same thing......

Any ideas?

I think they're hard to unlock on the bench. I test by assembling locker tooth on tooth then seeing if I can rotate each side to lock it.

Yea did that and it locks in.

Its set with the right clearance between the two cams too........

as long as there is room for it to unlock you will be fine. if you can push back the half by hand to unlock it then it will be fine.

The distance between the two cams 0.146

It recommends 0.145-0.165

So just put it all back in and take it out for a play.... ?

whats the difference between the sides ?
thats more important spec to check

0.035 each side so its centered too

If the lokka is working properly you will hear it click when turning on the seal, and two wheel marks on grass when you put your foot down.
You can also test that it is unlocking by putting a small piece of tape on each of the rear wheels and going for a drive, on seal, turn some corners and the pieces of tape should no longer line up.

aw well I will stick it back in tomorrow and see if it works.

It says I can use factory oil?

any thing better than factory people use?

excellent

standard oil is fine. some go for a thicker oil to quieten down the noise. ie go from 80w90 to 80w140. tho i wouldn't use thick oil if your in snow country.

I have some 80w-90w. will see how it goes

How did you get on w this? Would be interested to see how the R180 responds to being locked. Your a manual trans right?

didnt know they made lockers for the r180 front diff?
only for the rear h233b???

auto lockers for r180 have been out for years. arb now makes a selectable for the r180.

A lokka item sets you back $590 NZD ish.... depending on exchange rate

Welcome to the world of positive front traction!

Just avoid off-camber scenarios, and if the CVs start to bind (click), back off. This will typically happen at full droop when you are uphill, stuck, so maybe worth checking that the upper bumpstops are still there. So long as CVs stay within working angles, its all good.

For years ARB refused to make a locker for the R180 on the basis of strength, but aftermarket demand became so high that they gave in.

I think its plenty strong, you have to really be giving it some love to break it. (speaking from open R180 exp., not locked)

Looking to lower my front diff now.....
