Has any one had to replace their diff cause of a winning noise if so how would it cost roughly

No my ute yet and its done 200k, when was the diff oil last changed! I see some adds from people selling their ute's say about 3k

Had a few, usually due to wrong fluid or not regular changes, or in the case of utes, being under a heavy load all the time.

Usually just a matter of replacing side bearings, pinion bearing, collapsable spacer, seals etc. So long as all the gears & clutch packs etc are still all ok. Around 5-8 hours depending on how much needs doing, if it's an IRS (which most are) the whole rear subframe has to be dropped out and put back in as well.

I was told today that one of the ford dealers does about 1 a week apparently a real common problem in the ba falcons

Not just Falcons, Ford Diffs in general.

At my work (Which is also a Ford Dealer) we would easily average a diff a week, whether its on a Falcon, Explorer, Escape etc

You need to drive a Holden if you want to hear a "winning" noise!

(Sorry, nothing constructive to add. I'll get me hat & coat and see meself out.)

i might be wrong but i was told someholdens use the same diff but dont have enough power to break them lol

It's a 2004 xr6 with 90,000kms on odometer, meant to be whining, not winning!

Ford have an inhibitor fluid to quieten them down around $170.00 try that first.

I find it a bit hard to swallow that the differential is stuffed after 100,000km unless someone has be giving it its rasberrys.

you need to use a friction modifier
unbeatabull, Jun 28, 6:53am
They do take a specific Oil. We use to put Penrite SHC-ID in ours until Ford told us they wouldn't cover any warranty claims with his Oil in it . however we never had a problem with diffs after putting it in! The one Ford recommends now is Castrol SAF-XA.

Personally, Id just chuck some Morey's in it!

I thought your usaul BA/BF XR6 does not have the LSD as standard
Only the Turbo/F6/XR8 and some other variants have the LSD and they both have different fluid requirements

Castrol SAF-XA and Nulon Full Synthetic 80W-140 Heavy Duty Limited Slip Differential Oil) is the ones to use for the LSD and have the additive already,have used both and prefer Nulon and is a PITA to do without a hoist

What is moreys is that a oil!it has had the oil changed in it spoke to the mechanic today and he said he replaced it with a penrite oilbut it still whineshave someone looking for a replacement diff but could fit it up and still be the samenot sure what to do its probably going to cost a bit though
unbeatabull, Jun 28, 8:08am
Moreys is a stabilizer/thickener/additive.-
It doesn't necessarily fix the problem but could certainly make it a bit quieter!

LSD was a option on purchase in base models, XR6 came with LSD. XT etc it was an option if the buyer wanted it new.

My diff is a LSD item jacked up the other day and it says LSD on the yellow sticker
