Hey people..

Looks like im about to throw a 9' LSD into my stock XC

Its all standard at the moment... with Drum Brakes and all that.

I know Uni's will have to change... they are worn out anyway

Any Hints or Tips on the Install ?

I know people talk of Splines n stuff... anyone know anything ?

Thanks

I think i might just bolt it up with the Disc's.

As far as i can figure at the moment.

The Uni's are different.
I need bigger "U Bolts" for the new set up
A different brake cable.
And possibley a new brake booster(some most say i can retain the same one)

The rest just bolts in basicly... As far as i can gather

Disc is the go. Don't bother with drums if you have the disc option available.

Rear Uni = yes
U-Bolts = yes
Handbrake cable = yes thers a difference btw drum and disc
Brake booster = nope (same)
Master cylinder = nope (same less a biasing valve)

I have an 9" XC disc brake setup in theback of my XB.

What about the Shaft(between the box an Diff) ?

I think they are the same Length... Or do i get it Cut n Shut ? :fraz:

I sell bearings for a living, and just converted for a guy last week. All you need is a uni on the diff end, which is a half of a RUJ-2038(tailshaft side) and half of a RUJ-2039(diff yolk half) . The partnumber for special uni is RUJ-2029. Go see a CBC Bearings oulet with this number and all should be good. Ideally, you should get a tailshaft suited to a 9 inch, as the unis in them are stronger (outside clips), but with an auto it should hold up. Dion.

They are pretty rare (like hens teeth) and getting a tailshaft made up is also hard as you need the front and rear sections before they'll make you a shaft. Finding an original 9" shaft is hard because who'd sell their tailshaft? It's not like you wouldn't need it.

Any V8 shaft will do the trick without issues.

I am going to get one made. The company i work for bought the Hardy Spicer company about 3 years ago. That is where i will order my stuff. I got the materials to make a new shaft for a mate, who put a 9 inch in a v6 Hilux, and it all worked out good. Just got to select the right tubing, weld yolks(2) and a slip yolk for the gearbox. maybe a new spline yolk for the diff, if you go large uni series.
