front axle

will the swivel ball from a defender fit a series 2a ?
i ask cos it would alow for easy conversion to disc brakes on the front or is there diffrence somewhere im not seeing ? half shaft !

That would be waaay too easy. No they don't fit sadly.

Its the same sort of problems as using the whole Disco Axles; would save welding leaf saddles to the bottom of the tube, but would give bigger problems elsewhere.
The swivil doesn't actually fit, the flange drilling is a different patern, though that could be 'adapted' by filling the holes with weld and re-drilling.
You'd have to use the Series UJ in the swivil, and from memory, the 1/4 shaft lengths are 'out' to the dimensions of the coiler swivil; overall, I think that the assembly is a tad to short to get the drive flange on the end, though I suppose you could try machining an n'th off the end of the stubbie to get it to fit, but the main one is that the UJ doesn't quite line up with the swivil hings, so steering would try slightly bending the shaft!
Though again, bit of HD engineering, I spose you could make either Series of Coiler joint assemblies work.....
NEXT, though you have the bug-bear of the reversed steering arrangement, and the same hassle as using a coiler axle in its entirity, in that the series track rod is ahead of the axle, coiler behind, and the akkerman arms aren't interchangeable; and it's now complicated in the fact that neither series or coiler track rod would fit between the akkerman arms, as they would be closer together than on a coiler axle, or at the front of a series one; plus the spring clerance issue, and the same niggle at the drag link, and radius arm ratio from steering relay.....
In short; not a very viable mod; actually more, not less, hassle than using complete coiler axle, with all associated problems considerations, risks, warning and advice over that one.

And also as teff's pointed out on an earlier thread, the reason why the swivel hinge points are diffo is because the effective suspension geometry is diffo, I cant remember which way is which, but a series is a leading link, and a disco is a trailing, hence the need to re-drill the hinge points.
I went well into i vestigating the possible conversion of a disco axle, and gace up due to the complexities, there is one way that will work without massive mods and thats to fit the disco front axle with spacers under the axle to make space for the track rods, be ok if you dont do much off road.

well that answerd that question

thought it was a loser before it started but thought i would check lol

cheers for quick relys

Surface area of the shoes and drums would not give you such an increase in benefit anyways, although I suspect you were thinkin disco axle so that maybe you could fit a lt77 or something.

Pardon? this seems to be answering a different question!
Suspect he fancies the idea of discs becouse its a 2a 109 which wont have had the big brake drums or a servo as standard, and has an effof heavy body on top!
11" Stage 1 or 1-ton brakes; new parts including backing plate, some-one recently priced up at around £300 I believe including master cylinder and servo.
alternative would be Paul Haystees, I think Brembo based, and TUV Approved (I also believe) disc conversion kit; but probably more than twioce the price.

yeah i seen in a mag a conversion kit but its about £750 or more per axle and i cant afford that
so when they went disc they went coil and diffrent steering all at same time then

Pretty much; 1983, twelve years after the Rangie was launched, and rotten ones were starting to turn up in breakers and people had started building 'hybrids' out of them, factory decided to do it themselves and standardise parts accross the range.

Rangie itself, got disc brakes and reversed steering from the start; as it was pretty much a clean sheet project, which Land-Rrover have only ever done about three or four times in thier entire history...... Original Landy being one, the Rangie the other, the FREE-LANDER the next until they launched the third generation Range Rover and Disco!

With the oddity of the 101.... which was a SORT of clean sheet project, except that to keep costs down, they dsort of retro engineered a Range Rover. 101" wheel-base comes from leaf springing a Range Rover chassis, which is essentially what they did, then dropped a forward control body on top. and maybe the Llama....not that it ever saw production.

Shows what happens when you talk ****e, I stand corrected.
