Sierra diff Rebuild Tools
Litemoth - 6/7/09 at 09:32 PM

Does anyone know the dimensions of either of the features shown between the red arrows below?

They're the Ford tools for setting-up the crown wheel and pinion. I can remake the tools if someone can spill the beans on the dimensions??

Seems that info on diff servicing is held in the realms of a secret society....Maybe I'll have to become a Mason or something?

judging purely by the number of replies you have had, I think you are right.

There has been a a couple of questions about splitting / refurbing diffs - the answers have been pretty unanimous - 'Don't do it' !!

Apologies for the negativity, BTW. Steve.

If i suss how do it, I'll blow it open and publish a guide. It ain't rocket surgery and people have been setting up diffs for donkey's years ....

I guess it's a case of people staying quiet and looking after their business...fair enough i suppose.

I'm off to suck up to a Ford dealership

if I read pic 15-019 right I don't think the dimension really matters. it looks as if both ends are tapered to sit in the bearings and the threaded part just pushes the bearings into place. therefore the dia between the to arrows doesn't matter as it's only to check bearing runout.
just why god only knows.
very much doubt if a ford or any other dealership would know how or even want to rebuild a diff

We rebuild diffs at work the problem is we don't have any info for the sierras anymore.have you tried looking on eBay for the workshop manual. But as others have said don't do it they need shimmin up and new crush washers that I'd assume are no longer available from ford

i got a copy of the diff rebuild manual if that helps?

saved, will have a proper read later

The parts must be available, people fit ATBs to these all the time and the bearing kits are on ebay. It cant be that much of a black art

Got bored, had a quick browse. Do you just have the pictures, or do you have the actual manual?

If you have the manual and could get it scanned that would be awesome as a few bits are barely readable. Otherwise it seems to have all the required detail

Hi there

Don't know if this will help you any but there are lots of manuals etc here, some diff stuff and if you scroll down the page some Sierra manuals.

If you want the parts for the diff then Midland Transmissions will sell you them. I spoke to them about my gearbox and diff and to make one V6 gearbox from two original boxes (4X4 V6 front on to Diesel rear) with complete new innards, and recondition my diff, again with all new innards they quoted me £500 which I thought was a bargain.

Cheers

Hi

Sorry I forgot to give you the link for MTS

http://www.gearbox-mts.com/home.html

I spoke to a man called Gavid who new exactly what I was talking about, which suprised me because I didn't He was very helpful and told me to ask for him if I called back. Might be worth a phone call for parts and dimentions of the tools etc.

Cheers
Colin
