in a freelander they might've found themselves taking full torque in first, ie when pulling a trailer, accelerating at full throttle. Whereas,
in a bec, they would probably only see full torque in top, which obviously would have a serious gearing reduction in torque. Shame i cant put figures
to it as i dont know torques or ratios.
Fitting it isnt entirely straight forward. On a sierra diff, the bolts are infront of the driveshaft, whereas the freelander has them behind the
shafts. There is an adapter available but this probably adds a fair bit of weight and costs. Ideally you would entirely remove the sierra mounts to
reduce weight, then fabricate a cradle to hold it in place. I have one fitted to a chassis in the garage, i'll take a photo but its not perfect
as it needs redoing.
Eventually, when i get it right, it will use a total of 24" of inch square 16g to mount the diff and locate all rear bones, top and bottom. brb
with a photo.

looking at it again inspires me, its been a few months due to the fact i welded it all in off centre... 
in the long run, i'll redo the lower bar in inch round, with a threaded insert in the open end to take the rear leg of the bottom wishbone.
24" seems a bit optimistic, seeing as theres already more than that now! Maybe get it down to 24 and use 3 lengths of 19mm round to brace it
sideways, the red lines in the picture.
The stuff that looks like bird crap in the picture? It is, not poor welds! The poor soul died in a bucket of oil...

Put a lid on it  I never leave any uncovered now since a wren landed in the oil tray. I feel guilty about it still.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

it will have custom shafts, once i decide what to use at the wheel end!
Pete, good thinking, really i should just take it to the tip but you know how these things take forever...

Can't you use 5mm plate to fasten the diff to the uprights at the end of the transmission tunnel and get rid of all the frame round it. There
shouldn't be any need to brace it sideways as there shouldn't be anything pushing on it. The wheel end will be located by the wishbones
and the joints slide in and out same as the Sierra don't they? Get some cut to clear the driveshaft like the ones they use with de dion setups.

Westfields Mega series (Blade, Busa, Bird)use the freelander diff so it can take the power OK, although theirs are modified with LSD's.
Westfield also do mounts which adapt the diff to standard Sierra diff mounts.
Can't see them being that expensive given that Westfield parts are generally very realistically priced.

That's what I was thinking of, should be plenty there and access to the diff will be easier. Get the plasma cutter fixed Joel  .

you have a worryingly good memory pete! I'm led to believe that it just needs a new nozzle, might give it a go one day. The problem with using
5mm plate is i hope to mount the wishbones onto the diff support too, as im sure that this will reduce total mass involved. I just need tio wait for a
spot of motivation and a blue moon

FYI I had to speak with Westfield today about a backorder.
Righthand bracket for the diff is £34.60, Lefthand is £18.38.
Bargain.

Is that to bolt a freelander diff to a sierra diff mount?
What about driveshafts and uprights?
Opinions are like backsides..
Everyone has one, nobody wants to hear it and only other peoples stink!

just for interest - are the front & rear freelander diffs the same? ('cos if so the front one is effectively going backwards....)

You couldn't pwn your way out of a wet paper bag, with "PWN ME!!" written on it, from the "pwned take-away" which originally contained one
portion of chicken tikka pwnsala and the obligatory free pwnpadom.
