Roley94 Member 114 Member For: 11y 8m 14d Gender: Male Location: Perth Posted 18/12/19 09:18 AM Share Posted 18/12/19 09:18 AM 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 the fg diff is 50mm then that confirms it. Link to comment Share on other sites More sharing options...

BeerTurbo Donating Members 241 Member For: 6y 6m 14d Posted 17/05/22 01:47 PM Share Posted 17/05/22 01:47 PM 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.

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.

BeerTurbo Donating Members 241 Member For: 6y 6m 14d Posted 18/05/22 02:59 AM Share Posted 18/05/22 02:59 AM 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 Link to comment Share on other sites More sharing options...
