Hi guys,

Well last nite was an interesting one for me, i had just gotten home from quite a massive weekend down at the gold coast (Summa Field Dayze) and i have broken sumfin in my Soarer.

When leaving the coast i pulled out of from a set of lights and it felt as tho i had driving over a piece of wood on the road as i heard a small clunk and felt a jolt.
Kept rolling.

Anyways, got home to brissy a good 50mins later. Pulled off from a set of lights turning left (not driving hard) and 'BANG' .. loud noise and my car jolted.

I pulled over pretty much straight away for a look see but couldnt see anything obvious , so i carried on again.

I think ive done my diff or a driveshaft as my car will travel nicely enough going straight but when i turn corners with my foot on the accelerator, it seems to jump and clunk around the bend.

Does this sound like a diff drama ?? Im thinking maybe lost a couple of teeth and the noise is when the loose bits are being picked up and run through the remaining cogs ??

Spose its just as well i bought a Torsen LSD only 2 weeks ago.

any ideas ?

*sorry for rambling post, its kinda hard to explain.

I know the feeling, sounds like same issues I had when I did my diff. Unlucky, but lucky for you that you have a new LSD instead of having to replace it with another Open Wheeler like I had to =(

Sounds like you have removed some teeth from the Crown Or Pinion Gears....

Problem with this is, You may have the Centre, but you WILL need a new Crown and Pinion wheel to use in your housing. Im hoping you have just destroyed the spider gears as this means you can just get your Torsen Centre installed with your current gearset.

More likely you have broken the Crown or Pinion teeth, but heres hoping to some Spiders that have gone Splodey.

I Busted Mine at the Drags in November. Had a Massive Bang come from the diff when coming to a halt. The numerous Bangs and clunks, SPecially when turning corners. I needed a whole new diff, and luckily Neil came through for me. But NOW.. Heaps have LSD's for sale.

Best of luck with it.

Crown wheel is the Big one which Bolts onto your Centre. The Pinion gear is the smaller one which bolts into the Housing and mate with the Crown wheel.

I'd guess it's just the spider gears if it only clunks while going around corners with some power applied.

Hehe, sounds like its locked! My old ute with the Mig Diff used to do that if you went around a corner too slow (read: without breaking traction. Navaras have huge axles, never broke em.

Update people ---

Although i couldnt get away from work early enough to start on my diff, i did drain the oil from it....

well attempted to anyways - very VERY little oil came out *starts smacking forehead* STUPID STUPID STUPID

Im starting to think the reason it went bang was due to having minimal oil in it... now all it has is metal pieces.

** LEARN FROM MY POO MISTAKE PEOPLE! **

Silly really, in my job we have to check ALL our vehicle's fluid levels every month including diffs, kinda wish id checked mine in the Soarer now.

Anyways - ill try and pull it out tomorrow and inspect my Crown and Pinion for damage. Hopefully they are not stuffed and i can re-use them.

Also i called Castle Hill Toyota and they can provide me with the new stuff i need to get the diff rebuilt.

2 x Diff Bearings ($160)
2 x Diff Seals ($50)
2 x O-rings ($10)

It will probably cost me about $250-270 to get my LSD centre and everything put in and built when i take it to a diff place near my work.

** HMMM starting to get expensive.

Im looking around for a complete bolt on replacement diff with casing now which may save me having to re-build my bits..

Hot tip from lew:

- Aristo will fit

- JXZ90/100 Chaser will fit

- JZA80 Supra will fit (NOT 6SP Manual one tho)

would all the cradles be the same ?

Dont feel bad, my friend bought a JZA80 6 speed TT. Got it from the transport company, drove home gently. Didnt check anything, went fanging for about 1 hour only to hear that lovely sound of a big end bearing destroying itself.

Pulled the dipstick, dead dry!!

Does anybody know if the whole assembaly from other Toyotas can just bolt straight in ??

i.e drop my diff then simply slap in an LSD item from an AUTO supra or Aristo etc ???

Im just tryin to figure out whethers its worth me gettin my thing rebuilt with the new diff centre etc.

It all depends on whether my Crown and pinion are stuffed... if so, im goin to start hunting for a WHOLE assembaly .

*** NOTE - this job is more of a pain in the ass than i thought it was goin to be.

I also need to get a new WEBO Flange or whatever.. the thing with the 3 bolts that connects to my tailshaft. Mine has fractures. Wonder how much that is goin to cost ?

The WEBO is perfectly fine with cracks in it..

Everything you have asked will be found by searching.

YEARS & YEARS of Info are readily available if looked for..

The Information Super Highway that we all used to think of something then search for it has now become a thing of the past..

hahaha my first ' DO A SEARCH ' comment... it was only a matter of time i spose ... 990 posts later

Thanks Neil , i guess its better to come from you than another.

Reason so many of us ask is because we all want to hear that 'Its ALL going to be OK *insert name here* ' and i prefer to hear it from someone i know / know of as opposed to 'SIC_GTS69r' from other less reputable forums such as boostcrusing and the like.

anyways, thanks again people.

In that case i will not replace my WEBO and i will keep searching for a complete diff from a supra or aristo that i can simply bolt up.

Then , if im lucky, ill sell off my diff centre and re-coup some costs.

Right im gettin somewhere with this but only very slowly.

** Next question - Does the V8 diff look the same as the TT diff ?

Its just i may have found a LSD and the guy says its from a TT but im not sure about him (only because i have not dealt with him before) and i want to make sure im buying a TT diff and not a V8 diff.

What are the differences ? I understand the ratios are different but what does that actually mean .

*please forgive my ignorance , but im slowly learning about these diff thingos !

Also thankyou Neil for your advice and help (via email) of late.

Does the V8 diff look the same as the TT diff ? -Yes.

What are the differences ? - The ratio's are different.

What does that actually mean? - It means the output rotational velocity will vary for a given input rotational velocity.

Also, It's hard to tell if it's a torsen or not, as they will both act like open diff's without a torque differential across the diff.

There was a really good thread about it last year. But I can't find it ATM.
