Hi,
Yesterday i had to use my diff lock to go to the guarage as i found the front diff case, gear kit consist of two large 24 spline and two small, two pins broken/ damaged badly. I found a thread here that early puma had 2 pins and later ones have 4 pins suggesting 4 pins are a better option. My question is that is it possible and better to fix a 4 pin to mine instead of 2 pin? Appriciate your suggestions/ ideas. Cheers. 
Kind regards, Diluk |

Hi Andy,
Many thanks for your info. Hope you can help with me to find the part numbers. The diff case part number FTC5399 which i will have to buy for sure. So if i am to fix the 4 pin shaft with gears, the part number I guess is TCI100070. Is this alright? Please share your ideas. Thanks. Appreciate! Kind regards, Diluk |

Sorry can't help with part numbers, but know how to change a diff
Can you get hold of limited slip diff for reasonable cost where you are? That's what I would do. Andy |

Diluk, have you asked your dealer? I understand that if LR will replace a broken 2-pin diff, they now automatically will install a 4-pin diff anyway. Worth the question.
Eric You never actually own a Defender. You merely look after it for the next generation. http://youtu.be/yVRlSsJwD0o https://youtu.be/vmPr3oTHndg https://www.youtube.com/watch?v=_GtzTT9Pdl0 https://www.youtube.com/watch?v=ABqKPz28e6A https://www.youtube.com/watch?v=rLZ49Jce_n0 https://www.youtube.com/watch?v=XvAsz_ilQYU https://www.youtube.com/watch?v=K8tMHiX9lSw https://m.youtube.com/watch?v=dxwjPuHIV7I https://vimeo.com/201482507 https://www.youtube.com/watch?v=ZSixqL0iyHw |

Many thanks for the ideas Andy and Eric !
Today I found in the breaking yard discovery 2 rear differential unit but do not they are 24 spline as mine. I will check that soon as they have to dismantle it to see now. But if it is 24 spline, could it be 4 pin and can it be fixed to my front puma diff? Cheers. Kind regards, Diluk |

A D2 diff centre should be a straight swap in the front end, with the possible exception of the flange which can be swapped from your broken diff.
It will be 24 spline, but will only be a 2 pin centre I wasn't aware of the 4pin centres in new Defenders, Is that the case for all 90/110/130? 4 pin centres front and rear? Thanks Peter |

Hi peter,
I thought all LR rear diffs are 4 pins? Please go through this thread hope it is useful. I think late pumas have 4 pin diffs fitted already. http://www.defender2.net/forum/topic16591....fferential So i am thinking to buy the LR D2 rear diff and swap them as you mentioned. My only concern is since it is a used 2 pin one, would it last longer? Other option would be to order the new gear kit and the case from the UK online store (brit car) almost for same cost but that could take 6 days wait. Thank for the info Peter!  |

In theory it would be the same strength as the one you have already broken. I have a D2 diff as a spare I run when I have either of my locked diffs out of my defender 90 (td5)
I guess you need to weigh up what you need / want and whether the d2 one is a good price compared to getting a 4pin, or repairing yours along with the time factor. |

certainly I'd be looking towards Ashcroft for a replacement diff (LSD) they are strong and fit for purpose |

I would order one of these
http://www.ashcroft-transmissions.co.uk/in...ductId=173 Or preferably http://www.ashcroft-transmissions.co.uk/in...ductId=259 Second one is very good value for the money, and will be much stronger than a Land Rover four pin diff. Andy |

the front diff is the harder one to get to. Since you have broken it, you might as well spend some money and get the ashcroft LSD (ATB) and the labour cost is going to be the same to either fit this or get a replacement.
the rear diff is practically a bolts job and is way easier than the front. So do yourself a favour and get the ashcroft one. I've them on my diffs and it works wonders especially when emergency braking without ABS. keeps the truck so straight in line. From the land of the most expensive land rover defenders on planet earth. At �125k for a XS 110 csw and you get to own it only for 10yrs! Please find me a good reason to stay on this island. |

Had the same problem on my '07 110 a couple of years ago.
Pre 2010, 90, 110 and 130 TDCi's all had 2-pinion front diffs. Post 5th July 2010 build date, 110 and 130 models have 4-pinion from diffs, but 90 models still have 2-pinion. All TDCi 90 models have (as far as I known) 2-pinion rear Rover-pattern diffs. All TDCi 110 and 130 models have 4-pinion P38-pattern diffs. I fitted an Ashcroft ATB when my fromt diff failed since it is stronger and superior in every respect to a LR 4-pinion Rover pattern diff. It also costs less as an outright purchase than a LR standard diff bought on an exchange basis. (Unlike a genuine diff, it has also been built and set up properly by people who care)! Changing the front diff is actually not much harder than the rear. The trick is to disconnected the two steering rods, unbolt the entire swivel assembly on each side from the axle tube, and pull them a couple of inches outwards. Doing this doesn't require any further dismantling of the hub or steering, and you don't need to disconnect the brakes. You do however need to leave the wheels on (to support the hubs) and to make sure that the steering arm is supported when the swivel hub is unbolted to stop it dropping and straining the brake hose. Also bear in mind that the swivel hub assembley complete with wheel is heavy! It is easier to do than to describe and takes about 3 hours working solo. |

Interesting that a new 90 comes with a different front diff arrangement than a new 110 - thought they would have shared common components in this area.
Funny what you learn on this forum! |
