Replacing the diffential

[Casar66]

How on earth can I reinstall the differential without using a lift and without getting furious?

Jack with either a diff carrier bracket on it or a sandbag. either way its a bit of a balancing act.

Put diff on trolley jack hold it down with long and wide cable tie done it a lot of times 

[Casar66]

Mmh, have no sandbag and no long cabletie either. I tried it with a tensioning strap but that could not hold the differential in position on the jack.

I made up a simple wooden saddle for the diff, and used cable ties to hold it onto a jack. I put the front rubber washers onto the support rods and taped them in place before lifting the diff. I recall I had to raise the front of diff a little and then move the trolley jack forward a little to get clear access to support rods at the back end. It was tricky and I had a few goes at it before success. Took a few tea breaks as well along the way! Good luck.

Hi Casa66

my last diff refit involved  using some long 8mm studding.  (2  may work but 4 is better.)  3/8UNF to M8 adaptors and some large washers.

It is then a matter or engaging the diff onto thew studding and then screwing it up.  Very tedious but does work.

You can use the crocodile jack toi raise as high as possible to remove some of the tediousness.

Lie on your back drag Diff up onto your chest lift up into position and hold in place with you knees until you manage to get fixings on,it’s doable believe me I’ve done it.

Hi Niall,

when I need mine doing I'll give you a call. As much tea and biscuits you can handle.

Having done it lying on my back, I’m glad I now have a lift and a transmission jack!

If you don’t have someone to help hold it on a trolley jack, a sandbag is easy enough to replicate with a bag and some soil from the garden.

Not enough space for the lying-on-the-back-number.

As a typical German, I have found an extremely sophisticated and ingenious solution.

I ended up doing something similar. The wooden saddle was the solution

+1, I've done it that way but it was nearly 50 years ago!!, at the time I thought"F*%@K me" if this comes down before the first nut goes on I'm dead!!         Would I do it that way now? .....  NO absolutely not!!                                                                                                                                                                                                                                                                 Cheers Rob

Done this also but not for the feint hearted. Now have a hydraulic motorcycle stand that I have welded casters to. Best tool for gearbox and diff installs.. (I know the tr gearbox goes in from above, but my stag goes in from below. )
