Buying a new Diff

[Jordan]

Hi everyone,

My name is Jordan, have recently bought a CF long wheel base beddy in classic lime green acrylic. Haven't started to restore it yet but I am getting parts together for when i can start, just have to finish building a house so I have a garage to work on the stallion.

I am looking at purchasing a 9" diff at the moment because most of the driving will be on the highway as i'm planning to deck it out as a camper. The ratio of this diff is about 3.86:1 or pretty close to it (think that's how you say it). Just wondering if anyone could give me some advice as to what kind of price is reasonable to offer and if this ratio woud be good for high way cruising, bout 110 kph, my CF has a red 202 and a 3 speed auto. This diff was behind a 308 if that makes any difference and it is a complete rear axle set up with the dual wheels etc all attached, no springs though.

Any advice would be really appreciated.

thanks.

Hi Jordan...Welcome to the bugger website.That diff sounds like a good idea,especially with that ratio. Should be good for hwy cruzing.!If you are building your house make sure you get the biggest garage you can. Beddies take up alot of room!!! cheers...johnno

Hey  Ben and Johnno,

thanks for the reply, i'm gonna go check it on saturday $500 sounds like a reasonable starter.

the garage is plenty big enough for the beddy, it was actually a consideration when working out how high and wide to make the garage. It's funny how these vehicles become part of your life, i've been looking for a new rental lately until the house is built and looked at heaps until I found one that had a garage big enough for the van.

cheers fella's.

sorry johhno but i cant agree with you on this one.. i doubt you will be happy crusing at 110 with a 3.86:1 diff.. it will be fairly reving hey! unless you get yourself an overdrive gearbox which will make it perfect..

 but the good news is 9 inch centres are easy to change yourself.. they are a banjo type diff meaning you can just unbolt it from the front pull the centre out and replace it with another.. (have to pull axels out too, and drain oil first) so id buy it put it in. see how it goes. if no good look around for another centre closer to 3.25:1.


wishing i had one of those right now.. just blew up my hwy borg diff on the weekend.. now need to get someone to change the centre for me grrrrr..

might even have to put my 9 inch in to get me out of trouble for a while.. lucky i got a spare van at the moment im running around in..

hey benny bro, don't use the mate that has my B/W diff, still waiting after nearly 18 months or is it closer to 2 years for him to do the repair !!!

[ben]

good idea ed!! hmmm i am so gunna have a go myself ay..

ready a  post on the net about doing it yourself.. he says make sure you put everything from one diff to the next and make sure everything gets put in exactly the same way..

off to look for a borg wagner centre, 21 axel spline, LSD, borg centre, 3.5:1

hmmm wonder if im a bit to picky??

I love this web site, I feel like I'm sitting in a pub having a beer and talking about my van.

Well I bought the diff, it's a 9" welded into a CF dual wheel base rear end, i have to pull the cover off to check the ratio, it came with four tyres, two bald and two brand new and I ended up getting a power steering rack for $300 and a pretty straight bonnet for $10 bucks aswell. Going back to pick up two machined drums some time in the future when i have some more coin. The guy was a complete gentlemen, I think I scored pretty well.

Thanks for all the advice, I might need some help to work out my ratio, Have no idea about counting crown wheel and pinion gear teeth so i'll probably have some more simple questions to follow.

cheers,

Jordan.

Oh and I forgot, The guy I bought the diff off suggested a turbo 450 gear box? I have no idea where this comes from? any help would be great.

cheers,

Jordan.

jordan what kind of steering rack have you got there? has it been converted to fit on the bedford i asume yeh? sounds fantastic!

10 bucks for a bonnet!! cant go wrong!!


are we allowed to know how much you ended up getting the diff for? always interested hehe.

turbo 450? never herd of it sorry.. but craig (hammer spanners) is organiseing me a adapter plate to run the turbo 700 gearbox behind my 202.. so i get the strength of a turbo v6 turbo 700 the overdrive gear.. and the cheapness of it also hehehe like 50 bucks off ebay!!!! how good!!!

yeh id suggest for hwy crusing youd want an overdrive transmission.. either a celica, supra, or the turbo 700 to name a few.. would e the go!

i dont count the crown wheel and pinion teeth.. thats too much effort for me anyway. but is more exact but if you knw what ratios the make came out with you can find out..

i jack up 1 wheel. spin it 2 whole turns and count the number of times the tailshaft turns. as simple as that.

if the shaft turns 3 and half times its a 3.5:1 ratio.

cheers
