Jim 123 Posted August 12, 2019 Share Posted August 12, 2019 Drive shafts and A Frame out first. Best to remove diff and carrier together. Leave the long top bolt in until last and support the diff throughout the process from underneath. You’ll need a long drift bar to ease the top bolt out. Best suggestion is to get Jonathan to supply you with the relevant build manual. This will also help for centering the diff and reassembly. Do an archive search on this site as there have been previous postings on the same topic. Link to comment Share on other sites More sharing options...
1WEL Posted August 14, 2019 Author Share Posted August 14, 2019 Just a quick question So I’ve just put the car up on axle stands and looking to remove the diff. Once I’ve removed the brake caliper, is it easier to remove the four bolts holding the de-dion ears to the tube and remove the whole hub assembly with the drive shafts as one unit.

SM25T Posted August 14, 2019 Share Posted August 14, 2019 Yes. You can remove the brake disc and hub, deDion ear and drive shaft as one without undoing the 41mm nuts. I use a trolley Jack under the diff with a 200mm square bit of plywood on the pad ... enables you to lower the diff single handed after removing all fasteners.

Wrightpayne Posted August 14, 2019 Share Posted August 14, 2019 I usually pull the whole hub assembly rather than undoing the driveshaft nut. Just need to be careful not to damage the diff oil seals when re-installing - its quite a heavy lump! Link to comment Share on other sites More sharing options...
