Ute Axle Length

[Roley94]

I can’t find the thread discussing the different lengths between the b series and fg Ute diffs and I cant remember what’s what, I’ve just pulled the axles out of my ba turbo Ute and put them next to what I know are bf xr8 axles and the ones I pulled out are about 25mm longer. 

 

I’m quite sure turbo and xr8 diffs are the same. The Ute has also had a zf conversion so I wouldn’t be surprised if the whole diff was swapped out. Would that mean I have an fg diff in my ba?

if your BA ute has been converted to ZF, it's either a BF setup or a FG setup, but either way it'll be a 2.73 LSD diff (if it was the full driveline kit from whatever car the ZF came from) and it does have different axles and lengths.

@OZYWALKER can confirm but pretty sure FG diff disc to disc is 40-50mm longer which would agree with what you're suggesting

[Roley94]

Yes it is 2.73 ratio but the label on the diff is gone so I can’t tell if only the gears had been swapped into the original diff or if the whole diff was swapped. If the fg diff is 50mm then that confirms it. 

[OZYWALKER]

I can measure it on Sat to be exact if you like but I can 100% say that the FG axle is 50mm wider than the BA/BF axle for the utes.

[Roley94]

Don’t worry about measuring it, I’d say it’s definitely a fg diff then. 

 

Thanks guys

I smashed an axel in my b series ute.

So now im having fun finding a replacement.

I have what I thought was just a 373 ba turbo manual diff.

 

My spare diff from a xr8 ba lsd has different length axels.

I just had a guy measure his on marketplace. Bf turbo auto, axels measured same as my spare.

From the metal collar before bearing, they are 73 cm and 67cm.

 

One im trying to find is 70cm for that same measurement.

Quality search and info find. Well done.

To answer your question. Your farked

Sounds like your doing a diff swap or alot of ringing and measuring.

There appears to be a shop selling them on ebay. They can probably give you a measurement.

I measured both my diffs and they are the same. 1500

Both LSD 

Different length axels.

 

Yeah I called some local driveline places n they said ford genuine.

The ebay shop said they have the one I need yes.

 

I was hoping to buy sh axels cheap. But looks like ill be buying new.

 

Just kinda annoying there different lengths. Be nice to have spares
