from memory I think the widths are different from WMS to WMS, other then that no reason why it can't be done. Are you replacing the control arms at the same time as the factory ones are weak

I know WT has the tie rod in front of the housing.
I'm pretty sure coily has it behind.
WT has low pinion diff centre whereas Coily has hi-pinion.
Will the swivel hubs interchange?
If the widths are different a custom tie rod will be needed.

This is something I have contemplated myself, but every time i look at it i can't see the justification.

As for width, never measured it myself, but from info i can find, the wheel track between a Coily and WT are the same, but the Coily has a different offset wheel, so it would make the WMS-WMS wider on the coily, so going to a WT axle will narrow the track slightly, but not by a significant amount.

As far as steering is concerned, the draglink is on the front just like a WT, which is the more important bit for steering box location. The tie rod is in a different spot, being on the rear unlike the front on a WT, but if you used a complete WT front end, that becomes irrelevant anyway.

Diff ratio is easy, just get rid of the 3.7 from the WT and get a 3.9 to match the rear.

Obviously you'd take this as an opportune time to throw away the the strut set up and revert to a Jimny style setup, also would have to go to a custom links to get rid of the stock ones, then out of all that also redesign the suspension to lower the roll stiffness to try and match the rear. Also move the axle forward a little to get more clearance in the back of the guards.

Whilst it may resolve the front end issue, give options to stronger parts and lose the need to have a locker modified to fit, it's where i get stuck on the idea. You've just ended up with a fair bit of custom work and really no further in front then just buying a WT and doing all the usual tried and tested modifications.

If going to that effort, may as well just go that bit more and throw something bigger underneath and play around with the rear to suit and stretch it out that end also. That way you only needed the chassis rails to begin with and it is irrelevant if it was a coily or WT you started out with.

if you want a locker you just use a jimny one with a modified carrier.

well thats what i have heard.

coilies are wider and they don't have a steering dampner standard and the steering link is at rear of diff

The coily pinion flanges are the same size as narrow track. The coily is 35mm wider in track than a wide track

coily diffs also use vitara stub axles and bearing arrangement. i'v done a few conversions now coverting from high pinion to low pinion so people can run airlockers and diff gears. there is a fair bit involved ie- machining etc, but the results were good.

Hey Joeblow, how did you put a low pinion front diff head in the coily diff? Did you use WT steering knuckles? What axles? What CV's? Tierod? Im wanting to do this conversion in mine.
