yoeddynz Posted September 6, 2011 Share Posted September 6, 2011 Our van is pretty good off road for what it is- but the first thing that lets it down when things get slippery is the back axle. Its very easy to get a wheel spinning. I would love to fit a Lsd but I have heard that its hard to locate them for early hiaces? I would have to keep it the same ratio as the front right to prevent windup on harder surfaces. Where could I find out what ratio is in the diff is in the axle- are there any really good toyota 4wd specialists I could try. From what I know the Hiace axle is narrower than a hi lux one- or the other way round- either way I dont think its a straight swap in?

CaMpylobacter Posted September 6, 2011 Share Posted September 6, 2011 chuck a 'lokka' centre in it? or a chinese air locker. both miles different from each other but probably better than an LSD. Quote Link to comment Share on other sites More sharing options...
Spencer Posted September 6, 2011 Share Posted September 6, 2011 Pretty much all Hiace's have had the G code diff in the back since the 70's (check the build plate), which is the same as a Hilux. Track down a Hilux LSD and bang it in basically, the factory LSD's aren’t the best as they don’t have lock up ramps (no good for d1's) but with a tighten up should be sweet for your van. There is some issue with some high ratio Hilux gear sets having different offsets, but I’m no expert and can’t confirm, in saying that I've put a few Hilux LSD centres in Hiace diffs now with no problems Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted September 6, 2011 Author Share Posted September 6, 2011 Sweet- i'll have a look at the build plate. So the lsd bit fits inside the crown gear and is swapped like for like? Apart from once changing a pinion oil seal on our old beford tk I have no experience with the inner gubbins on diffs. If they dont make a noise and have good oil in them I sort of leave em alone so this is all new shit to me. How is a locker diff activated Cam?

Spencer Posted September 6, 2011 Share Posted September 6, 2011 A air locker will set you back a fortune compared to a factory shimmed LSD. Yea carrier unbolts from the crown wheel, bang the lsd in and setup lash etc accordingly, its easy. I'll try dig you up a factory service manual for a similar diff Quote Link to comment Share on other sites More sharing options...
Spencer Posted September 6, 2011 Share Posted September 6, 2011 OK, so here is a manual for T & F series Toyota diffs (two smaller diffs) basics of setting it up once you have it back together are there though http://www.toymods.org.au/forums/tech-c ... c-lsd.html Quote Link to comment Share on other sites More sharing options...
NaN Posted September 6, 2011 Share Posted September 6, 2011 G series diffs are in the Hiace. Since your is 4WD you [HAVE] to have the same ratio as the front. (which you probably know already). - I'd set up an auto search on trademe for 'LSD' under toyota parts (diffs and axles), wait it out, filter through the list each day, it will only email you new listing, within a couple of weeks you'll have a good feel for the free-market pricing on the item. Then all you have to do is wait until one shows up, with the exact ratio you need/have to have. Price wise .. since I have a similar market research search going for LSD's around $250 - $500 depending on the rarity of the ratio, lower ones are cheaper, seen them as low as $200 buy now. Ignore the others, plate LSD's are fine, the for the golden solution a air locker would be the way to go. heres a great example for a good price. http://www.trademe.co.nz/motors/car-par ... 006201.htm http://www.trademe.co.nz/Track.aspx?sit ... 870159.htm < this is no use to you, landcrusier diffs are bigger phyically and wont fit the g-series housing.

Spencer Posted September 6, 2011 Share Posted September 6, 2011 Who cares about the ratio he already has the one he needs in his van. Just buy a LSD centre and swap it over, pretty sure the only changes as they got newer was bearing sizes, well apart from a few odd ratios which don't interchange with anything. Wouldn't pay more than a 2-3 hundred for a LSD centre, especially as they are usually old and loose as shit Are you buying one for your Capri niglewade? as factory Toyota Hilux clutch LSD's are pretty shit. Being spring loaded only with no ramps mean they are sweet for some extra grip in a truck, not so good in a performance car, can be made better with springs etc but still pretty mud Quote Link to comment Share on other sites More sharing options...
kpr Posted September 6, 2011 Share Posted September 6, 2011 ^ this ramp modded hilux. or trd, cusco etc irs center. is only way to go, for anything other than some more straight line grip, as spencer says. Quote Link to comment Share on other sites More sharing options...
NaN Posted September 6, 2011 Share Posted September 6, 2011 I was thinking that the right ratio would avoid the swap over cost / adjustment effort. but if thats no issue, I'd go with a lock right for off road, just my opinion though. re capri: nah, rather use a torsen or lock-right .. I need different gear set (3.X:1) to what I have (4.3:1) so will deal with the issue then. Got the perfect mags for the look of the car, only to find rear offset is out, need to shorten diff by 85mm each side. No issue, spoke to steelie gears and diffs are us. Going with diffs are us. Saw the huge stock of customers diffs at Steelie gears and freaked out, didnt want to joint the back of that queue. Quote Link to comment Share on other sites More sharing options...
NaN Posted September 6, 2011 Share Posted September 6, 2011 http://home.4x4wire.com/erik/diffs/ http://www.4x4wire.com/toyota/tech/lockright_locker/ <-- makes for a good read on lock rights. http://www.trademe.co.nz/motors/car-par ... 453751.htm <-- these used to be on tardme for g series diffs, if I remember right were about $500 ish.

kpr Posted September 6, 2011 Share Posted September 6, 2011 http://gearinstalls.com/ i'd run auto locker type diff in front if wanting more offroad grip. unless its full time 4wd. lsd rear for nicer road driving Quote Link to comment Share on other sites More sharing options...
NaN Posted September 6, 2011 Share Posted September 6, 2011 ^ above site was one I was looking for, excellent reference site. for toyota diffs cannot think of a better site. this user on trademe knows toyota diffs, he can tell you what would fit a early housing.
