Helpful, clear and informative. Thanks.

A common thing you might want to do is drill them hollow. That way they twist a bit more before snapping entirely. Very common for people using the original rear diff in drag cars etc.

Or just get a real diff and it will hold, welded diffs eat driveshafts.

@@smurfvolvo You say that but try launching the car hard with lots of torque and grippy tyres, or lift one rear mid corner with a torsen.

@tracklizard4018 yeah keep drilling and welding dude I'm sure it's the best solution ever, even though it's been proven to be shit over and over again.

My welded diff has lasted 4 years, I snapped one shaft but only because of axle tramp because all of my bushes were dead, I poly bushed the whole rear end and had 0 axle tramp or snapped axles. I’ll likely upgrade to LSD and beefier shafts at some point though since I now have about double the horsepower

@@smurfvolvo How has it been proven to be shit over and over again? In what use cases? Torsen is a kind of LSD, more like a reverse open diff, that has been "proven to be shit over and over again" as well, yet a lot of people love them and they work fine for their use.

Was it the original rear axle or did you change it? I read on the forums that it cannot withstand high power.

Did you not use an actual gasket on the differential cover. Looks like you just used a flexible sealant product?

@tracklizard4018 4 ай бұрын

Commonly you'll use make a gasket there instead. Works just as well if not better honestly.

If you weld the diff with the shafts still in place, the heat affects the strength of them (softens) and they are more prone to twisting and shearing off...apparently

Very interesting, I hadn’t thought about that, I don’t know the history of the diff or the shafts but it’s a possible factor if it was welded with the shafts in situe, the worn bushes causing axle tramp were definitely not helping either! All good now since the replacement shafts and the whole car being poly bushed

Loved this, mine diff has given up the ghost, where did you get the replacement?

@driftbricker Жыл бұрын

A friend sent me two replacement shafts, I was lucky 🙂 it can be difficult to get the shafts without buying a whole rear axle since it turns a rolling shell into an ornament.

@mikolishken23 7 ай бұрын

After putting the shafts back in, do you just hammer it back in to re-seat the bearings in the diff?

@tracklizard4018 4 ай бұрын

It should slide in smoothly. Having done this a lot I've never had to hammer them in. They just click in and you press a little. If anything the bearing will be the issue but I throw SKF LGMT2 on it.

Check Drifts and Lifts KZbin channel. On one video he said that hole needed to be drilled deeper in driveshaft. That will prevent snapping off.

Is the 940 driveshafts on the 740 too or are they different

@tracklizard4018 4 ай бұрын

There are longer and shorter versions and generally speaking the longer ones are more commonly found in the older vehicles. Most important is honestly to just put them in the same way they sat prior to removal if used. If you switch L/R you'll end up twisting them opposite of how they've been twisted for the past 30 years.
