RAWDEAL 222 Posted February 5, 2015 My project car is nearly on the road , and it just has a leaf sprung e series diff in it I was going to put a LOKKA in it as its only a pegger diff at the moment whos running one? are they any good ? The price seems right for me , i dont like the whole clutch cones wearing out idea either Share this post Link to post Share on other sites
wagoon 2,429 Posted February 5, 2015 Yeah I'm keen to hear any experiences. I was dead set on one but have moved away slightly, just no quite sure how they affect handling especially understeer. For the money they are defiantly worth a look. I think 4:15 mark of this video is quite telling as I would say the driver is on it Share this post Link to post Share on other sites
NZXD 2,328 Posted February 5, 2015 Is the lokka the set up that only locks up under torque loads and then relaxes when not under load? Has a sort of clunky sound when engaging??? Share this post Link to post Share on other sites
wagoon 2,429 Posted February 5, 2015 Yep activates when torque is applied and deactivates when no load is placed on diff. The first series clicked quite bad when driving around corners but newer ones were suppose to be ok . Apparently there is also a large driveline shunt when they do engage.

slydog 7,873 Posted February 5, 2015 We run Lokka's in our line truck's Isuzu's and Canter's and the bang when engaging @ low low speeds like take off is horrendous. Makes me wonder how long the diff will last for. That said with a car been MUCH lighter and the design may be different to compensate for it. Share this post Link to post Share on other sites
wagoon 2,429 Posted February 5, 2015 checkout this video for explanation on how it works. The brand that fit our falcon diff(e series only) is 4WD systems 2 slydog and gerg reacted to this Share this post Link to post Share on other sites
wagoon 2,429 Posted February 5, 2015 XC did the lokka break? Did you have any issues with axles breaking? Share this post Link to post Share on other sites
gerg 10,871 Posted February 5, 2015 They're quite expensive lumps of metal... On the upside though, you re-use your open centre so no need to fork out for a limo centre. May need an adjustment in driving style (ie not too early on the power out of corners or off it too late going into them) but I've been told that they are livable in an everyday situation.

slydog 7,873 Posted February 5, 2015 Well someone who would be prepared to live with it for it's advantages will have ZERO issues IMO if the car units are better than the truck stuff. I use a 31 spline full spool in my ute and have no complaints at all. Drive it around and too work on occasion and it drives fine TBH. Even taken it to buy beer and it doe's car parks easy as...just point and stab...most people just move out of your way 3 Thom, Crazy2287 and winton reacted to this Share this post Link to post Share on other sites
wagoon 2,429 Posted February 5, 2015 Greg they are half the price of one of these http://www.harrop.com.au/store/driveline/truetrac/ford_xf-au Also half the price of a kaaz which requires a fair bit of maintenance and also requires rebuilding when clutch plates wear Just look on your tube for aussie locker noise or lokka noise or lokka issue you can kind of get the idea 1 slydog reacted to this Share this post Link to post Share on other sites
RAWDEAL 222 Posted February 5, 2015 Noise or not . If they work like an LSD , and dont cut the lifespan down on my driveline . ill be buying one ! Share this post Link to post Share on other sites
wagoon 2,429 Posted February 5, 2015 They arent an lsd they are a locker. Lsd's are designed to slip on their clutches but the Lokka has no clutches it is either 100% wheels locked or operates like an open wheel diff when you are off the throttle. Share this post Link to post Share on other sites
RAWDEAL 222 Posted February 5, 2015 ill correct myself lets me slide around corners and do burnouts*** 1 Crazy2287 reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted February 5, 2015 As long as you're aware of the changes it makes to the handling then i reckon they'd be ok. Just don't come a gutza on an off-camber bend in the wet... Could be ugly. 1 Outback Jack reacted to this Share this post Link to post Share on other sites
Trev Vaa 1,185 Posted February 5, 2015 the locker itself failed, i wasn't the first one either, lot of people i know have had issues with them. i snapped plenty of axles with the spools etc a tru-trac from VPW is the same price as a lokka, harrop rips on prices for detroit lockers, spewing they are the only company in aus that makes the TVS blowers. http://vpw.com.au/Category/Index/6782 go the tru trac you won't look back.

wagoon 2,429 Posted February 5, 2015 Im guessing the centre pin snapped in the lokka?? Yeah I know eaton is cheaper but I cant find a part number for the 0578 e series BW. The only one I could find ws the harrop one which I do agree is a stupid price. Share this post Link to post Share on other sites
NZXD 2,328 Posted February 5, 2015 I've had a look at the Harrop ones, but at $1500 nz I'll just have to live with my factory LSD. I spoke with a guy who has lokka diffs in his 4wd, says he can hear them clicking in and out. Share this post Link to post Share on other sites
Outback Jack 6,352 Posted February 5, 2015 In that link above that XC put up the detroit tru trak is 650 bucks and there is a 28 spline. The tru trak has a much better design without clutch packs and doesn't need to be adjusted. That is an LSD design. Lockers are locked all the time, like welding up your centre, or chucking a spool in. You lose wheel nuts, break axles, and its a bitch to park, best suited for the track or burnout cars. The Outbacks Hydatrak diff was one of the best produced LSD's around, but their downfall is they have a silicon filled centre, when this overheats the LSD loses function and can fail completely, and seen as the hydratrak coupling is not servicable, it's a new one (pretty much impossible to find now) or change it over for something else. I will be going trutrak in my ute. Jack. Share this post Link to post Share on other sites
gerg 10,871 Posted February 5, 2015 My Subaru has a viscous centre diff similar to the hydratrak and on trips longer than say 1/2 hour, it locks up and chatters around corners. Mind you, it has close to 300,000 on it. 1 Outback Jack reacted to this Share this post Link to post Share on other sites
gerg 10,871 Posted February 5, 2015 It's funny how some diffs are brilliant and others are rubbish, even using the same design. Toyota still hasn't got their LSDs anywhere near right. Bloke at work who's owned 2 Hiluxes and a Cruiser reckons their limos are absolute shit, whereas the same clutch pack design in a Nissan Patrol he reckons work really well and for a long time.

wagoon 2,429 Posted February 6, 2015 Just rang VPW and they said the eaton is to suit BA onwards so thats the BW80. The only thing VPW have to offer is spools for a e series BW78. Thats pretty much inline with everything I have come across. The only options for a bw78 is standard lsd, 4wd systems lokka, kaaz lsd, harrop truetrac and spools.
