GM89 Posted November 5, 2023 Share Posted November 5, 2023 Hello, I need some help identifying the year of vehicle the front diff came from. I know it was a 110 defender and it’s the front diff but I can’t find any information about the year of vehicle it fit. The markings on the casing read HRC 1124 ROVER 11 03 08 And the markings on the bearing caps read HRC 2669 Lee SG42 18 A 08 I can upload pics if needed. Thank you Geoff Quote Link to comment Share on other sites More sharing options...

uninformed Posted November 6, 2023 Share Posted November 6, 2023 Going by the crown wheel bolts (and they look factory) it’s post 98. They look like the good ones that only ran 3-5 years before the change to a lesser quality flanged head bolts. Prior to those in the photo they are not flanged head bolts.

Hybrid_From_Hell Posted November 6, 2023 Share Posted November 6, 2023 Morning Just like axle casings the vast majority of the numbers mean very little, they are either makers numbers (there are to my knowledge 7 different companies who made casings for LR and the main number is just a part number. The casings themselves can vary therefore even from front to rear on the same LR if when it was built different casing Manufactuers units were grabbed. What you have there is one of the last units, it might be a collected unit but can't tell as there is no picture of the "flat" part of the casing..... If the entire flat is flat its non colletted, and if there is a big "V" groove its a later still and colletted.- but weak Crown wheel bolts are FTC5150 HD Flange head so dates 98 / 99 onwards all of these are Long Nose units, 3.54 24 spline. The carrier caps with the hollow roll pin are also one of the worst made, these pins are known to fall out bend or snap off, and in some cases even shear off the cast part holding the pin, this was a cost cutting idea from LR and one of their worst, and even more bonkers is on 110 / 130s - a genuine 3.5 Tonne towing machine ALL short nose diffs have this roll pin !. We get at least 1 - 3 a month of these in for repair / failures. As a diff its one of the weakest LR made for Long Nose units, the "Puma" flange being round is an improvment, but the casing material is lighter, and the cost cutting makes it one of the least desirable ! We do use these but we back engineer the issues to make them stronger - and more like they should have been when made ! Nige Quote Link to comment Share on other sites More sharing options...
Snagger Posted November 7, 2023 Share Posted November 7, 2023 How is the cross pin retained? Does it have a circlip at each end, or is it one of the really awful type with a single roll pin through the carrier into the cross pin like my wife’s 2009? 1 Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted November 8, 2023 Share Posted November 8, 2023 Yup, awful designs both, yes late pumas are held in with 1 x pin, some with a circlip but as the entire unit is weak its a matter of place your bets as to what breaks 1st :O( Nige Quote Link to comment Share on other sites More sharing options...
oneandtwo Posted November 10, 2023 Share Posted November 10, 2023 The diff caps on later diffs, certainly since the early 1990’s, are date marked, that one was made on 23 Jan (A) 2008. The diff centres are marked similarly. 1 Quote Link to comment Share on other sites More sharing options...
