swoping 200 axles for later 300 series (24 spline ones)

[scatt]

I'm hoping someone will be able to shed a little light on this swop, I know the suspension components will marry up and so will the prop but i'm a little in the dark about the brakes, will i need to run a 300 series master cylinder and new brakelines or is it a little more simple than that?? All advice gratefully recieved. And thanks in advance Scatt :D

At some point prior to the introduction of the 300 series, the mounitng bolts for the callipers increased in diameter to 12mm, so the earlier ones don't fit without drilling and later ones down't fit safley on older axles, but AFAIK the piston diamters where never altered, all coild sprung LR used the same pistons/callipersd EXCEPT the bigger Defenders which have bigger callipers on the same size disk(vented disks in that case).

The springs, shocks, pipes etc are all the same or compatible, it's the guts that are different though you might notice the ends of the driveshafts are different, all 300 axles should take alloys safely.

Would i be able to swop the 24 spline diffs/ half shafts/ drive flanges from the later axle into my earlier 10 spline ones???

That depends.

Early axles had 2 oil seals either side of the bearings, if you have these axles then I think you can fit later half shafts with little problem, that being that the bolt in early axles are imperial and later axles are metric.  The early bolts may be loose inside the later drive flanges (assuming one-peice halfshafts).

If you had 10 spline ABS axles then they have one seal inside the stub axle which runs on the half shafts itself.  Often this seal needs swapping if you change the halfshaft.  I think the drive member bolts are the later (thicker) metric ones.

you should find that a 300 series axle will have a very similar build, so they should work in ABS style axles.

the diffs all have the same mounting bolt pattern AFAIK.

Thanks for info RRB, i have been searching around today and there a 10 to 24 spline axle conversion on ebay. included are new hubs, stub axles, bearings, seals, half shafts etc. Then its just down to the diff. the only bits you keep are your axle casing and brake calipers! So this looks like the best way forward or i will try to find some 24 sline axles and strip them and rebuild mine. :dance: winner!

Holy cow, I'd think it was cheaper to swap the whole axle.

[scatt]

OH :(.  There is another option but it would depend on a 300 series pedal box fitting and that would change the brakeline set up and help fit 300 series axles.??

I just took out the 10 spline halfshafts and put in the 24 spline ones,  As above just need to make sure the drive flanges are the right ones in terms of bolt size and whether they are thick or thin.
