Just ordered one. It will be a christmas present so it will be after the first of the year before I get to install it. Probably need to look into the front diff drop since it will be out anyway.

Not yet. that is now bumped to next on the list. Thought I had some lined up last week, but they wanted $160 for a used set of mile marker manual hubs at the junk yard. Luckily my birthday is in January so I will have some extra spending money coming my way fairly soon. Thats all assuming I dont end p having to spend a fortune trying to move over the next few weeks and then manage to get my money together and spent before we start building a house in the spring. Once that starts the wife wont let me buy anything fun for a while.

I remember reading somewhere a few years ago you want manual hubs for driving in the snow with a front locker or lsd and to only lock one of the front wheels. Any truth to that, not that we get much snow around here.

Yea that's true. My front diff is welded.. so if i tried to run both hubs locked in the snow the front would push the tires forward more than help turn because both tires are spinning at the same speed.. unlocking one allows one tire to spin at a different speed. I also have to unlock one hub on tight turns on dry trails.. otherwise I'll have to make a 5 point turn lol

Just clarifying that its not an LSD, its an auto-locker. It is different in that it will allow differentiation, but, by allowing one tire to go faster, under power, while the slower tire is ALSO still under power.

Its not allowing any tire to free wheel like an LSD can after it reaches the break away torque setting.

For ~ $350 DELIVERED, its hard to beat.

:D

Totally. 350 is a heck of a deal. This may be coming sooner than some other things I've had planned.

Hopefully Santa will leave some extra money under the tree ;)

You were considering doing the diff drop - and, as you'd be messing with the diff anyway, if doing the Lokka, do the diff drop at the same time to streamline things and kill two birds with one stone, etc.

If they're having some really good deals I may jump on this sooner than later. And yeah, if/when I do this, I'll definitely do the diff drop as well.

I'm posting this here as its about how this thing works:

I had a conversation with RJ from Lokka to be sure I understood how it works. I then compared that to other auto-lockers, and wrote a summary of the conversation as it relates to the X. (2000 - 2004)

They have a front locker for the 2000 - 2004 X with the R200A front diff.

http://lokka.com/site/


They have us listed as WD22 (2000 - 2004 X) and they break it down by 4 or 6 cycl versions.

They ALSO have a front version for the N50 (Second Gen X)


The way it works, is it locks the cam gears to the axle gears (The teeth mesh)


If you are going straight ahead, on soft ground so there's slippage, or, on the pavement, the gears stay meshed, and the two tires are driven at the same RPM.

If you are going around a turn, on soft ground so there's slippage, the two tires are still turning at the same RPM, and the gears stay meshed.

If you are going around a turn on pavement (Or other high traction surface where you probably didn't need 4wd anyway, etc...) the OUTER tire has a longer track to follow, and, on the turn, will be made to turn faster by the road itself...

When this makes the one tire start to roll faster than the Cam gear is driving it (when cornering), it rolls off the cam altogether, then, the little teeth ride up and separate the Cam/Axle gears...... so the outer side tire (which is now turning faster) is able to 'free wheel' around the corner.

The Cam Gear IS STILL DRIVING THE INSIDE TIRE...but the axle gear of the outside tire is allowed to freewheel because it has the ROAD rotating it.


If there was slippage, then the road would not have the traction to rotate the tire, and, the cam gear would remain meshed with the axle gear for both sides.


So if there is so much traction that the road is pushing harder than the drive train, the Lokka lets the road have that tire and the Lokka continues to rotate the INSIDE tire.

When the turn is completed, the cam and axle gear on that side reengage and both sides turn at the same rpm again.


OFF ROAD, and/or other slippery enough situations, the ground will NOT have enough traction to over drive the cam gear, and both sides will remain locked together.


Similarly, if you are off road, and you hang one tire in mid air, both sides remain locked, and the two tires, even the hung one in mid air, continue to turn at the same RPM.

If the hung tire were to HIT something that would act to speed its rotation, so that for example NOT turning faster would mean that tire was BLOCKING your progress if it CAN'T rotate faster, then it does unmesh that side and let it roll while, again, still driving the other tire still on the ground.

You could theoretically simulate that, if you were to grab and yank the hung tire to make it rotate forward faster...it would let it rotate rather than fighting your forward progress.


It engages and disengages the free side very quickly, it can re-lock in a maximum rotation of 18 degrees (360 degrees divided by 20 teeth & gaps).

That's the MAXIMUM, assuming it has just unlocked, and must travel over an entire tooth to get to the next tooth gap. This translates to about 4" - 5" of travel.

If its half way across the tooth when the inside tires starts to loose what traction it has (assuming it's un-locked in a turn, off road, was on hard ground, but changed to soft) then it only rotates 9 degrees, = ~ 2" of vehicle movement.

So what this means is there is almost no difference in tire speeds when they lock and un-lock ... so there is almost no sudden tugging of steering or anything else as engagement or disengagement occurs....especially compared to other auto-lockers.

This is why for a FRONT DIFF....it's so practical.

With auto hubs, you can shift to 2wd and go in reverse as normal, maybe a hair further than normal, to disengage the HUBS, which takes the Lokka out of the drivetrain/perfect for DD use.

If you have manual hubs, you can dial them in/out as normal too.

With the manual hubs, you can also dial ONE side out if you are in a hairy situation where you can't get through w/o a locker, AND you need to make a tight turn on slippery ground, and want to reduce the understeer a locked front gives you...to tighten your turning radius. (If not, you have the exact same situation as with an ARB air-locker...you can be locked, and have understeer, or, unlock)


So, in summary...the cam gears are meshed with the axle gears and that makes both tires rotate at the same RPM...unless one tire is being forced to go FASTER by the amount of traction (Outside tire on the road in a curve, etc...), and making it go as slow as the inside tire would hold you back. (Same as on the road with a locked ARB holds you back by skidding/dragging the outside tire, etc)

By letting the axle gear unmesh if it is getting more forward traction than the engine/drivetrain can give it...the Lokka lets the inside tire pull you instead - still powered by the drivetrain.

For ~ $350 delivered, its a screaming deal too.

:D

A group buy would be awesome too if they would go for it, I think we have lots of interested people.

If not here, see if Pirate 4x4 has one again for example, as the larger the buy the better the prices, and, as a group, even a lot of X's will be teeny compared to a lot of Heaps, etc.

:D

They don't allow outside distributors, so a gb is unlikely, also on a different forum people are having issues getting there lokka's and they a getting a bill from customs

Got mine today. the shipping company (tnt consignment) has a fairly crappy website and I thought my package went back to australia after hitting customs in LA. However after calling them last night they assured me it was still in the US and cleared customs. It showed up sometime early today. took 4 working days to get form Australia to my house.

As for customs, any time you order anything from another country you can expect to pay customs fees. Those of us in the US just arent used to paying them because we can generally get anything domestically. small things that dont cost much generally get through without trouble, like the snorkel head I ordered earlier this year. But something as expensive as the lokka is getting a fee more than likely.

did you get hit with VAT tax? (IDK what it's called here) Import tax?

nothing yet, but I honestly expect to. I looked up the information on the harmonized tariff schedule at the cbp.gov website and found the section for the tariff code it was imported under (8708.99) and read through rules section relevant to that section and generally speaking there are very few things under that category that incur any type of customs fee directly from the US government unless the item stopped in another country while in the process of being shipped. The only reason I have any doubts about what I am reading is that there is one category under that chapter that incurs a 2.5% fee that is listed as "other" which has items listed under it with the last item being "other". So without knowing what that other/other category includes there is no real knowing what to expect. however I feel that the majority of the people I have read about online getting a fee from customs for the import are not actually get the bill directly from customs, but rather from the state they live in. this is the quote from the website.

Customs and Border Protection (CBP) does not collect state sales tax on goods imported into the U.S.

However, CBP will make entries and CBP declarations available to state tax representatives if requested. Some states occasionally review these documents and send letters to importers and travelers notifying them that they owe state taxes.

Other useful info I found

Merchandise Processing Fee (MPF) is charged on formal and informal entries:


  • MPF on informal entries is either US$2, US$6, or US$9 per shipment.
  • MPF on formal entries (for imports of goods valued over US$2500) is set at 0.3464% of the value of the goods with a minimum charge of US$25 and a maximum of US$485
So the way i see it, the max possible fee directly from the cbp is $18.75 and then your state can choose to charge sales tax on an item which for me would be $14.88. I assume the fee that most people are getting is the sales tax because is seems to come some time after the purchase is made, which would make sense if the state requested a list of imported items and sent out bills from time to time to gain revenue when needed rather than sporadically throughout the year.
