Cost to convert to LSD from Single

soulink · 10-06-2010, 11:06 AM

Hey guys,

My diff is screwed iwelded something to something, anyway these are the prices they gave me:

$450 for reco lsd
$485 for re-Trace (new barings and acid flush and seals)
$250 for labour and oil
(not including GST)
Now they want to add another $695 for 3.9 ratio gears

So jsut keeping the same ratio and LSD $1300(inc GST)

But if i want to change the ratio $2050(inc GST)

like am i gettin ripped?

ED Ford Falcon · 10-06-2010, 11:25 AM

Is the previous prices for your au you have in your signature?

If so these diff gears i saw yesterday scrolling through the forum! You'll have to go down a little bit in the listing

http://www.fordforums.com.au/showthread.php?t=11299333

I do not know the owner of these gears but they are supposedly brand new!

When it comes to diff's it isn't cheap because a lot of labour is involved and it is a specialist's job.

I recommend you visit/call some more diff places and get some more prices just to compare on!

If you are in Sydney area, i can recommend you to a good mechanic that specializes in diffs/gearbox's

Cheers

nah in melbourne unfortunetly, and i have rung around but the problem is, i am driving to canberra in the next two days and cant realy take it to another shop so...
And supposevly trans-diff is a great place to get you diff service/reco so ill wait for one more phone call.

ED Ford Falcon · 10-06-2010, 11:38 AM

he says he will post them to melbourne for around $20.

A lot cheaper than $695!

Good luck with it anyways mate, let us know what you do

soulink · 10-06-2010, 12:08 PM

ok its been done, $1950 $%#@ i hope i havent been ripped :( but i need the car thats the prob...

anyway will see how we go

soulink · 10-06-2010, 02:16 PM

allrighty so it is getting done, ended up finaly got it down to $1250 with existing gear ratio...
Now everyone sais that you have to run it in for 500k-1000k is this tru? also i seen the other post but do you relay need to change the oil after 1000K ?

Thanks

POELWYK · 10-06-2010, 02:25 PM

yep its true need to drive the car to a max speed of 80ks for 1000km then you need to take it back for a flaush

soulink · 10-06-2010, 02:37 PM

well im ging to be doing around 1800km before i can get the flush so should be ok

I hope so.Thats an extra 800kms of contaminated oil in you brand spanking new assembly sloshing around(lsd clutch pack run in).

soulink · 10-06-2010, 02:45 PM

so what is the go with the oil anyway, is it becuase of the wear and tear of the first 1000k that contaminates it?

Because of the bedding in of the clutches.If your getting it done at a diff shop they will have bulk oil so when you go back at 1000kms it wont cost anymore than 80-100$

soulink · 10-06-2010, 03:02 PM

hmmm ill see what he sais but remember im not changing the gears and its a reco LSD not a new one...

But i guess it still needs to be worn in

haha this is gonna be funny then driving all the way to canberra at 80km an hour

haha

FreddyDUZ747 · 10-06-2010, 03:04 PM

Reconditioned is new parts in old casing,rebuilt is rebuilt and could be old parts pulled apart and put back together..Fine line with these words when it comes to mechanics.

So is it getting new clutches ect or is it a 2nd hand low km LSD?

My diff in the BA cost just over 3K to build

and thats with original gears,just trying to make you feel better.

**Polyal** · 10-06-2010, 03:06 PM

Good lord!

You could have brought a written off XR6 for that price and raided it.

I hope its all working well, I would have sourced a XR diff and swapped it over. But atleast you know yours in all new I guess.

soulink · 10-06-2010, 03:07 PM

well i assume its reconditioned becuase the are the words we where swapping so...
what if its only rebuilt?
still need the embedding?

If they have half a brain which Im sure they do just listen to their advice regarding servicing ect as this ultimately voids any warranty.Not knowing if its rebuilt or reco is a worry as youve given the go ahead on an expensive exercise thats not fully understood in your mind.Maybe give them a buzz to double check what work is going to be carried out,much easier now than when their on the test drive with you.

Tristan, diffs and their repairs can be expensive unfortunately but it is what it is. Now, you've confused me. I thought you got quoted $1000? And yes, you need to go back at 1000k's and yes, baby it for that first thousand. It's important or you could end up with another bill. We paid $3200 for our diff work and believe me lol the car has been sitting on 80k or less for a week now lol. It's been hard and people on the freeway don't appreciate it but..

I'd jump on those diff gears that bloggs24 is selling. $200 for brand new? Buy this you must :P

soulink · 10-06-2010, 03:25 PM

i would like to, but i asked them if i where to put some different gears in later he is telling me that it would need another re-trace, dont think it will need another one of them, but they are appealing

haha we will see how it goes

FreddyDUZ747 · 10-06-2010, 03:31 PM

Gears will need to be marked up again ect so yes another retrace is in order if going down that path.What makes you think it wont need another?

soulink · 10-06-2010, 03:32 PM

well from my understanding, a re-trace gets rid of all the crap and includes new barings, if i only had a re-trace done like 3000-4000k ago, wouldent it still be clean?

It will need another re-trace. Think of fitting new gears as, I dunno say, matching things up. Know what I mean? You want everything nice and clean. I had the fairmont's LSD conversion & gears done at once. Just simpler in one shot lol..

I'd still buy them. Keep them for a while until you can afford to have them fitted. If you're not happy with what you were told, find someone else. You'd atleast have them until you found someone you're happy with. You're not in a rush to fit them right?

I personally follow a specialists advice but I am lucky that the people I deal with do look after me well when it comes to costs. Still, I follow all advice/options and I pay.

WHILE TYPING THIS I'VE JUST SEEN YOUR NEW POST. Lol you're really fighting this re-trace thing huh? Look, if you don't want to have it done then don't, but then don't be surprised if warranties are void. I guess you don't HAVE to but I personally would. I always do what's right for the car and look after it. Simple. In the end though, it's your choice.

soulink · 10-06-2010, 03:47 PM

Nah your right i would get one, but we will see how it goes, i might not REALY need 3.9 ratio's anyway 3.08 will be fine, im not building a racecar

haha

Well see I was kinda thinking the same thing lol. Main thing is that you get your diff done so that it's back on the road safe and get it done right so that it's not back up on a hoist somewhere

As for your original querie lol. Yeah, I'd pay $1250 or whatever it was lol, for a reco.

Stattic · 10-06-2010, 04:40 PM

Yes you do need 3.9s. You need 4.11s or 3.9s trust me ask anyone who's done the mod

soulink · 10-06-2010, 06:26 PM

ok picked the car up and drove it home, all seems good, the guy said i only needed to baby it at 80k for first 300k just for the barings, but he said they used a second hand cramble and hammy so they are allready worn, the diff has been completely painted black(not sure what thats for) and yer

All seem good so far

Sorry to say but its not a reconditioned diff with 2nd hand cradle ect.How much was it in the end?At least shes back on the bitumen.

How worn was the centre?

As to why they painted it black,to make it LOOK new and give you that nice fuzzy feeling of seeing something shiny lol.

soulink · 10-06-2010, 06:42 PM

lol

it came to 1250 inc GST
they said the centre was realy realy worn and shiny so it had to be replaced so yer

Just glad it is back on the road and they ofer 12 months warranty even though its second hand so im happy

MGM · 10-06-2010, 09:31 PM

ive had to get a brand new diff when a spider gear tooth went inside my lsd unit and wrecked everything, i paid 2200 for brand new lsd which they pulled apart and strengthened and brand new 3.45's which i already had in the car, now i want 3.9's so il have to pay the price for labour to set it all up again. at least its a reliable diff i spose

Great news Tristan. Good to hear it's back and running well. Must be a relief for you. Treat her nice

soulink · 11-06-2010, 02:47 PM

allrighty, just noticed driving it around ive done nearly 100k so far at below 80k and there is a slight noise coming from the back of the car, has to be either the diff or barings. its like a rubbing sound every rotation of the wheels, is this normal with new or rebuilt diffs and barings?

Thanks
