What is a rebuilt and refurbished Differential worth?

Post by jbp » Mon 07 Nov, 2016 7:40 pm

Hi All
My question is … what interest might there be out there in 107 and 116 land in a completely rebuilt/refurbished W107 differential, and what might it be worth?

The back story is that some years ago, after using my 1976 450 SLC as a daily driver for nearly 15 years, and partially restoring it in stages during over this period, I decided in about 2004/5, to undertake rebuilding of both the front and rear suspension.

I tackled the rear suspension first, and had the suspension stripped out, completely refurbished and, after cleaning and sandblasting the undercarriage and various suspension components, painting the various components and reapplying the original flexible rubberised undercarriage coating, reinstalled the rear suspension back into the car with all new mounts, bearings, links, bolts etc.
As part of the work, the original 3.06 open differential was completely rebuilt by a diff specialist in Sydney, using all new; seals, bearings, and other genuine parts, at a cost way back then of approximately $1,000.
The SLC was by that time no longer my everyday car, and it has only travelled about 20,000 klms, since this work was carried out.

Anyway, long story short, I was very happy with the result, but had always considered one day installing the optional correct LSD.
Over the last 7 months or so I have sourced the correct ratio LSD, and I am now in the process of having it rebuilt. I will then eventually swap it into the SLC.

I will then have the rebuilt original differential as a spare unit, which I was originally intending to simply add to my growing store of spare parts. But being a relatively heavy and bulky item, and given the unlikely scenario of ever needing the original rebuilt differential in the future, I have recently been giving some thought to perhaps selling the rebuilt original diff rather than store it.

Hence my question, as to what interest there may be in the original 3.06 differential and what it may be worth as a completely rebuilt unit?
I will be interested to hear the collective wisdom of the forum?
Thanks.

John

'the number' will vary..... supply and demand though, these are strong diffs, can run a long time and only so many cars clocking up the miles. But as you have found if your diff does go, labour makes it very expensive to repair. If someone posts up tomorrow "help my diff is gone" then it would be reasonable to ask a proportion of the outlay for them to fix theirs. But haven't heard anyone looking for one so then you are looking for someone thinking - have the space and never know if i might need a spare one day. If someone wanted to fit a v8 or higher powered engine into a W114, this diff would fit and the taller ratio would be so much better than the 3.9 or whatever they had - so could be a market there. If it was an LSD then would be any number of takers no doubt. Good luck though - see what others say.

Thanks Craig
At one point I did consider simply buying a correct MB LSD centre and swapping it into my existing refurbished diff.
In the end I decided to keep the original diff as a complete spare unit just in case. I am now having second thoughts about my original decision to retain it, hence my query.
I would have thought there would be many cars out there that may well now not be clocking up big miles annually, but that have already done so, and the diff whilst strong may be well overdue for some work. Especially as some of the values of those cars might be on the rise.
As you say, its not hard to run up a relatively large amount in new parts, let alone labour, if the diff is to be rebuilt to a reasonable standard.
Anyway... just putting it out there as they say...
Thanks for the response.
Cheers.
