xwroo

pretty sure xw came out with he 2 series housing (bw75 off memorie) so you can only fit up to 2.97's ratio in the housing if you try put 3.08 gears in the crown wheel with hit the back case, if you can find a 3 series borgy witch is a BW78 this will fit 3.23's and above ratio centers they are allot easier to come by  i was even running a set of 4.11's out of a pintara < (btw cheapest set of 4.11's you will ever find ) if you do change the ratio's just make sure you set the clearances correctly or it will blow with in 2 to 3 months 

i have also used 3.89's out of skyline's btw these are better then the pintara center as they are a 28 spline 4 pinion center
also the skyline r31's have 2 ratio's manual is a 3.70 auto is 3.89's
ford XD to AU also use 28 spline 4 pinion centers 
 LSD Rebuild be looking at around $400 to $500 for , LSD hemisphere machining , shimming and labour maybe a lil extra if you also needed bearings < only generally need this if the center is flogged out.

 not sure what would bolt straight into a xw mate , XD might be close being its also a leaf spring rear end axle length may also be different as well as the mount points

 

dont bother with 9 inch unless your planing on running sub 12 quarter miles with fat grippy slicks. or you are the A Current Affair Burn Out King!.

ive been running the stock lsd's for years , even go to archer field burn out comps with them , they do last just dont expect frying and dropping a clutch on a set of 255's will have it last more then 6 months.

diff in my old nc fairlane copped a really hard flogging good old borgy with 3.55 gears 16 months of peak reving and neutral to 1st bangs only killed the diff due to slaping a gutter and smashing the bottom of the housing and oil draine dout then i drove it for like 2 months with 0 oil lol

corty gets pretty much same treatment guts flogged out of it still useing a 28 spline borgy with a mini spool over 5 years old this diff and no troubles besides a bit of play back and forth from the centre its self to the pinnion gear.

all i do is keep them clean and fresh oil and they last , if it blows up at the end of the day ... 0 shits given unless i smash the housing , i just keep buying 2nd hand centres and axles pick them up pretty cheap , does not happen often enough for me to warrant the cost of buying a 9 inch.

if you start blowing them every 2 months ..... there is deff's something wrong with the way your driving . also 9 inch diff's are way over rated .....unbreakable i think not ..... blown my fair share of them.

always remember to have your car rolling forwards slightly and drivetrain preloaded before droping a set , its the initial shock to the drive train system that starts breaking shit < took me a few years to work this out lol broken engine mounts every week , gear box's every month , diffs every other month , glad ACA never gave a crap about hoons when i was 17 18 i would of been on that every week lol

the diff i had in the xw wagon before the 9" was a xy diff with a xf LSD center, that cost me $700 nz dollars, that was to to fit the LSD into the diff with new bearings throughout and new cones. 

Look on ebay and gumtree thats where I find them, also try face book and the other social media places(sorry I don't do social media so don't know them all) for importers. There is a place on the gold coast and a place around Sumner park area off the top of my head. When searching type in rim size and 114.3 and lots will come up (don't type in ford as most will not mention ford and you will limit your results and may miss stuff) Be aware that you need to confirm offset before getting to carried away as less than 5 % of the wheels you see will be anywhere near the correct offset, even a +20 wheel is going to cause issues.

I run a borg warner in the wagon with brand new genuine gears and a rebuilt lsd,i drive it with 0 sympathy (hence the million broken autos) and have never had a problem.
Don't forget all the xr6t's,fpv's and hsv's all run borg warners stock.
No need for a 9inch these days unless your going for burnout master at the nats or planning on running 8s.

Centre options for a borg warner are very limited and the standard lsd can wear out quite quick if you don't have a bit of mechanical sympathy. But 9 inch cost a lot to buy and will add a lot of weight to the car, if you aren't pushing big power or have specific requires then a borg warner will be fine.

Those are american car sizes. As Ants said it's either a 9 inch or a 075 borg warner diff. Yes either of these diffs can have lockers, lsd and spools but 9 inch has a lot more stuff available. I'm also pretty sure that the xw will have a narrower diff than later models like xd-xf which has the same model diff. best bet is to take a picture of the centre of the diff from the rear as we can tell what it is then and go from there.

No such thing as an 8 or 8 3/4 in an xw mate,just borg warner or 9 inch.

Yes they are getting very common, but doesn't change that they suit old fords to a tee

Mc racing have 18x8 and 18x9 for under $1500 with tyres. They have a little more dish than the simmons.
If you want something no one else has and would go secondhand look at import wheels. They do have the correct offset in 17 and 18 inch diameter wheels you just need to find them. Generally you will pay between $1000-1300 for the import wheel which are in pretty good condition. As an added bonus they are mostly 2 and 3 piece wheels they are all big name brands and are normally lightweight wheels

Thanks winton again. Gerg once I know which way im going with the steering I say the whole ram setup will be going. 

thanks again

Just to add, the steering box that came out was an XY 16:1.
He got lines made up & used an X series " tin can " pump.

Old Gaz may be able to help. Can't see why a XF box shouldn't do the trick but having never done it my self I would only be guessing sorry.

My oldman had a similar problem with his '62 compact.
Instead of butchering his chassis rail, he filled, drilled & tapped his steering box to allign to the chassis.
He then got a tool maker to " burn a spline " into the compact pitman arm to match his XD steering box.
The oldman is an engineer, so this is pretty straight forward for him.
Hope this helps.
Cheers stu.

Thanks stu it all helps mate.

The problem is the chassis needs modifing.
The box fouls on the chassis rail and the lower of the 3 holes that bolt it to the chassis rail dosent line up, its about a half a hole out.
You can massage the chassis with a hammer so the box will sit flush, it takes a hard hit to smack it in enough to do this but it can't be seen when the box is in place.
The bolt hole thats about half a hole out needs to have chassis cut and welded to change the position of it.
I have seen a box where the guy used the original hole in the chassis and modified the steering box, basically redrilling the hole and put a nut and bolt through it instead of the bolt screwing into the housing.
