Sounds like the trans or diff then don't it? Maybe some broken gears in the diff? Drain the fluid and see what's up there first I'd say.
And what is a holeshot? flooring it? neutral drop? brake torque?

Assuming its the differential what do I do to beef it up? Am I entering a dark expensive world of custom? I would have figured stuff would have held up better than that. I'm too early in the performance game to be breaking stuff. Ahhh I'm going for some beer.

06-27-2013, 08:49 PM #7When I bought the car it had an extra dif in the trunk with an extra cluster. I assume the PO swapped difs when doing the manual trans swap.

Swap that out if the axle gears are ok will take you like 5hr estimate.
There is a peachpart walkthrough on that, it's great.
But, we'll wait to see what initial investigations reveal.
And as you say match the cluster part # to the diff if possible, or fuck it, hahaha

That's really weird, I used to do brake stands and corner-sliding burnouts in the rain with my auto like it was my job.
Practically, just swap the diff it's not bad with a breaker bar. I did my axles in my driveway. Also, I feel your pain-we're not allowed to work on cars either. So I get to do all my work in the grocery store parking lot across the street.
I think you need to be a pioneer and be the first to convert a w123 to leaf springs using a Ford 8.8 with discs from a Crown Vic/ exploder/late ranger. They're like $200 complete on CL all day.

Can't speak to the gearing of your trans but with 4speed auto/3.07/stock tire the motor is spinning pretty high at like 65-70mph
Now with a 2.88 and a 8% larger back tire I feel much better cruising over 70mph. Now if only my alignment was tight enough to cruise at 80+ hahaha

For some reason, 2.88's appear to not hold up as well as the 3.07, 3.46, and 3.69 brethren. Perhaps the taller gear is a bit too much for the 185mm ring gear 1.1 liter case. Maybe a 210mm ring gear 1.3 liter case is what you need for your soon to be increased power.

hmm. This was a 3.07 but I was a bastard to it. Realizing the extra diff was welded, and other tweeks on this car, I can only assume the PO was hard on it as well.
I don't do really any highway driving at all so maybe sticking with a 3.07 is better for me. If I ever do go on the highway i am usually meandering off of the main freeway with no rush anyhow.

You will need to swap out the input flange as the 3.06's flange is larger in diameter than the 3.07. ... Unless you make a custom driveshaft to accommodate the larger diameter flex disk.
Axles will be a tight fit, but many folks were sucessful in using the stock axles in a 210mm diff. If you get a diff out of a r107, you may want to take the axles also. They would be theoretically stronger.

The one I was driving is on the right. Is that standard for the w123?
The one on the left did not have bolts where the axle joins dif. I saw one in a 126 at the junkyard today that looked more like the one on the left. I ask these questions because this was obviously someones project car before I bought it and don't know what is stock and whats not. Lol learning a lot about these freaking diffs right now.
Also here is a pic of the welded gears that I will not be using. Never seen welded gears before. It looks like a horrible hack job to me.
Also here is some info. I figure I shall connect the spider web of info for the future readers.

(07-09-2013, 12:49 AM)lgreeley83 As of now I think its stock. My hunt involves checking for one with bolts. Maybe 2 different editions with same gear different housing. Who knows.
It was an 82 126 I looked at today that didn't have bolts. Forgot to check the ratio.
I have a 2.47 diff from another series merc (gas v8?) in storage back home that I paid a fortune for. I'll try to remember to dig it up when I'm there this weekend. The mounting was very different, but you may be able to swap the gears into your housing? Don't know, I'll get some part numbers (assuming my Dad didn't sell it for scrap)

The 2.47 is from a 380 SEL W126. It's what I've fitted to my 107. However it is the large case diff and the drive flange is at a different height (lower) for a standard shaft. The bolt-on axle shaft flange type are from a later W123/W124 and the early diffs can be converted to suit these axleshafts by using a W124 plugin flange and 6bolt axleshafts from a late W123. Lots of bucks although it saves dropping the diff rear plate to change shafts.
On the left the 2.47 large case converted to bolt-on axleshafts. On the right a 3.54 small case plug-in shafts

I think my diff is not the same as the one you have picture, but honestly I haven't seen it in like 2 years when I packed all my w123 stuff up.

Evidently, the diff that was a pulled out from your car was a replacement diff as the original is the same case style in the left.

07-09-2013, 11:51 AM #40The different case style does not matter in the way it fits in the car, it is all the same. As stated earlier, the case with the bolts are an earlier style and the one piece style is from the later years.

why only the ones with bolts?
They are functionally identical apart from gear ratios, both types of axles will work with both types of diffs. Ive swapped back and forth before personally.
Its nice how you can swap diffs from 114/115 to 123 to 126s. I love that feature.
I put a mid 80s 123 diff in my 74 240 replacing one that had an external bolt flange, and ive put an 85 126 2.88 diff in my 123, just capping off the ABS port.
