rear hubs
scotlad - 30/9/03 at 07:55 PM

i've just removed the lsd and drive shafts etc from the back of an xr 4x4 sierra to put in the indy that i'll be ordering shortly. will these drive shafts fit into the mk chassis ok? also what other bits of the back end do i need from this car? hubs?? i'll be getting a standard sierra as a donor to get all the other bits- ie propshaft, steering rack etc. alas still waiting on my garage getting finished- cant wait to get started!!!!!!

lucky you, im still waiting for the solicitor to do the conveyencing on the house im buying which has the garage im going to remove to be able to build a bigger one which ill build my car in, not an mk of any description tho, just thought id tell you how lucky you are!

Yes they will fit, grab the rear hubs, brake calipers and mounting brackets, makeure you order the correct rear uprights form MK i.e. disc ones?

thanks russ- feeling better about my not-finished-garage now!

And cheers Austen- have put aside all the bits mentioned- just need to get rid of the rest now- cant wait to put it on the trailer on 2 front wheels only dragging its backside! just as well i have nice neighbours to help.....

Scotlad, if the XR4x4 had ABS, you will need to remove the teeth on the hub using a lathe or grinder. Otherwise they will not fit MK rear hub carriers.


ned - 1/10/03 at 02:39 PM

Sorry, just a quick question about removing those splines/teeth (I have an abs equiped sierra rear end too)

If you grind them off (ie angle grinder) will this be a good enough job? It won't unbalance the ford critical manufacturing tolerances will it?
And are they made of a machined casting or hardened metal, ie will a normal lathe cutting piece go through them or require something tricker?

sorry for the dippiness and hi-jack...

Ned.

This may help, or not:

I bent the rear suspension on my Primera playing in the snow on a car park. With replacement parts unavailable, yes unavailable for a 1996 car I bought second hand parts. The donor vehicle's hub didn't have ABS and a Nissan replacement was £120, so we put my old one on a propane stove, heated it until jolly hot (that's a scientific term) and whacked it in a vice. Whaddya know? The ABS ring dropped off and before it cooled we dropped it over the non-ABS hub. Job's a good 'un.

The moral is, it might be worth having a closer look at the hub.

Cheers,

Neil.

make sure that MK dont give you upside down rear disk uprights ! i gave mine back to them at donnie, i expect it will be a few blue moons before i see a replacement.....................


bob - 1/10/03 at 06:43 PM

the little splines on the hub for ABS are very soft material ally like,i machined them down to the steel no problems.

We had exactly the same!! But rather than going all the way back up there we re-welded them


ned - 2/10/03 at 09:21 AM

thanks bob,

see you sunday?

The sensor uses a hall-probe (magnetic) effect doesn't it? How can they be ali?

On my hubs they're definately cast into the hub casing. Instead of grinding them off and worrying about balancing etc. you could use a decent half-round file and widen the upright a little as I've done.

HTH,

James

James

Well they were not steel thats for sure.

Anyhow i said "soft like ally"

See you sunday and no sugar in mine

RichyMkIndy - 2/10/03 at 05:09 PM

I used a round file and opened the upright up, took a while but works find now, i didnt want to upset the balance by grinding the driveshafts.


siert - 2/10/03 at 07:54 PM

a customer of mine used his lathe to remove the metal off the drive shaft....he said it was high quality steel......(and that was a tech dept in a school)....anyway use a lathe to get the best result and not an angle grinder!!!


RichyMkIndy - 2/10/03 at 08:52 PM

just use a half round file and a round file. bit of hard graft but it fits perfect after!


MK Goldrush - 6/10/03 at 07:48 PM

The ABS teeth are indeed heat shrunk on. They are manufactured from Carbon Steel, so quite easy to machine. When we referred to "grinding", it was meant as machine grinding to retain concentricity not Hand Grinding which would indeed make the whole thing eccentric (raving mad actually!) and produce nasty vibrations at speed!

We reduced the diameter to 79.5mm diameter to allow for the upright bore being slightly out-of-round.

Incedentally, it is wise heating up a heat treated critical part - you wouldn't want to anneal the whole component surely - making it so soft the component is useless!! Personally, I would advise against using this method...


RichyMkIndy - 8/10/03 at 12:13 AM

i mean file off the rim on the inside of the hub not the ABS grooves


ned - 17/11/03 at 12:35 PM

Just for info to anyone who's interested I've now had the teeth machined off my rear hubs:

Before:



After:


greggors84 - 17/11/03 at 02:52 PM

Looks good, nice and smooth. How much did it cost for them to be machined off, i was thinking about it, but i just filed the inside of the upright down.


ned - 17/11/03 at 03:38 PM

A mate of my dads did it along with some suspension bits that needed modifying for £10. bargain.

Ned.


bob - 17/11/03 at 07:52 PM

Retired engineer with lathe in his garage did mine,just got lucky i spose.


scotlad - 18/11/03 at 07:05 AM

if you take them to MK with you when picking up kit, they'll machine 'em for you if you ask nicely!


James - 20/11/03 at 04:07 PM

IS there any reason that MK don't just make the whole in the upright a little larger?
Would seem it'd save a load of hassle/expense!

James


Alan B - 20/11/03 at 04:17 PM

and the upright would be lighter...


greggors84 - 20/11/03 at 05:49 PM

I hope there is no reason why MK didnt make the upright hole bigger. As this is what we have done. So i welcome anyone to tell me i have f**ked both of them up.

tomblyth - 2/7/07 at 07:14 PM

turned mine off on the lathe they are part of the casting they are not removed be heating like the nissans


kipper - 3/7/07 at 08:20 PM

Same here. I got the fitter at work to turn them off, all done in the afternoon tea break.
