Puglet1 Posted February 4 Report Share Posted February 4 I am about to fit a 3.6 diff into my Vitesse. The rear spring and suspension is already removed so I guess it’s just a case of undoing the Propshaft and the mounting bolts. I have the car on stands and a 3.5 ton jack. Is there a safe way of lowering the diff on my own or do I need an assistant? Link to comment Share on other sites More sharing options...
johny Posted February 4 Report Share Posted February 4 Hmmm its a bit of a lump and has to drop at the front, slide forward a bit before lowering down. The safest is to strap it to a trolley jack or similar and one person manoeuvres while the other controls the jack.... Link to comment Share on other sites More sharing options...

I didn’t realise that it had to slide forward a bit- so that is really helpful to know. Based on what you have said, I’ll get someone to help control the jack. I’ll need to work out how to strap it to the jack or make some kind of cradle. I’m pretty sure that I have seen a photo of a homemade cradle on this forum but am struggling to find it. Many thanks.

johny Posted February 4 Report Share Posted February 4 yes the two rear lugs of the casing slot into the chassis fixings so it can get away from you as it comes out... 1 Link to comment Share on other sites More sharing options...

Colin Lindsay Posted February 5 Report Share Posted February 5 Put a trolley jack under it facing fore and aft; get the bowl of the jack under the largest curve of the body to support it. Once the bolts are removed the diff can be lowered gently but also wheeled slightly forward to clear the rear chassis brackets, but it will need to be steadied so watch your fingers. If it drops straight down it will take all the paint off the rear of the chassis. You can put an old pillow or rolled up quilt on the floor below in case it drops, so it will land on something soft. Removal is forward and down, replacement is up and back. Some people will cut small strips of rubber, old inner tube or the like, to protect the chassis by slotting them into the gaps where the diff rear legs sit, so that if they drop onto the chassis they won't damage it. 1 Link to comment Share on other sites More sharing options...

Colin's method is exactly what I did when swapping the diff on my GT6. Nigel 1 Link to comment Share on other sites More sharing options...

Thank you for the offer but I am 2.5 hrs away from Luton (I don’t suppose you are going to the Stoneleigh show by any chance )? If not I’ll review Colins method and maybe attempt using some flat plate to make up an adapter of some sort. Link to comment Share on other sites More sharing options...

Hi Colin. Thank you for the tips, I’ll be able to assess which method to use tomorrow.👍 Link to comment Share on other sites More sharing options...
