What are you thoughts on welded diffs and/or Spools?

The internet tends to say that’s it’s EXTREMELY DANGEROUS in all caps as I demonstrated.

Kinja'd!!!

I’ve had one for a while now and have had no safety issues or anything resembling one under normal driving. Sure if you push the car you might get excessive understeer or oversteer but you have to try and make that happen. It’s been pouring down rain most the time I’ve had the welded diff in and it’s not like the car just magically tried to spin out in a corner. Im not really following why people thinks it’s so unsafe. It’s not like it’s unpredictable or something.

If you’re ok with putting up with the extra tire wear due to always spinning at least one wheel in corners, it’s fine.

As long as you’re aware of it, it’s actually better. More traction more of the time. A friend of mine had one, that car didn’t give a damn about snow with the spool in it. Said it actually made the car way more predictable in slippery conditions. (Though that could have something to do with the fact that it was an 80's Caprice and didn’t have much in the way of cornering ability anyway. It was cop spec so there’s that)

unsafe? nah. arguably more safe as its more predictable.

but increase tire where if you are lucky, driveshafts that will torque if you are not.

its hard on bearings, and can cause them to fail early, and unexpectedly....... they tell you the same thing about running spools on pavement all the time as a daily driver. i found a FEW 4x4 threads right when i was getting ready to put mine in, shelved the idea now for a little while......

Kinja'd!!!

they are great for limited traction stuff like dirt and mud, and even lots of straight highway driving, but doing a lot of tight corners in regular driving is asking a lot from the parts AROUND the spool....... if you run small, old, hard, tires that never bite or grip you shouldnt have much problem. once you start achieving traction, the clock is ticking........

I had a welded differential in my Kadett B Caravan for a half year. The spider gears broke and this was just a temporary fix. Functioning differential is mandatory here, so it wasn’t a completely street legal solution.

It was pretty ok to drive still. But the winter drifting wasn’t very fun though. Without a differential it became unpredictable. Due powerless engine (60 hp) and heavy rear it decided to go straight when the engine couldn’t keep the wheels spinning. It didn’t easily get stuck though.

A friend has a welded diff in a lifted 90's Ford pickup that he actually off-roads with, often. It’s a little annoying around town, but he’s been running it that way for years with no issues.

why would you? seriously, you risk increased tire wear, vibration from scrubbing around turns, and drastically increased chance of breaking driveline components. For what gains?

If you know what youre getting into you know what your getting i to. I see it as not enough cash for an lsd or drift special.

We’ve been considering going minispool for our Gambler 500 car, but I’m worried more about breaking an axle out in the middle of nowhere.

But first, we need some power, we can’t even lose traction on a heavily graveled road in our ‘79 Cougar

Plenty of friends have ran welded or spooled diffs in the past on lifted trucks/Jeeps. If you do a lot of wheelin’ the pros outweigh the cons IMHO.

I’ve also ran auto locking rear diffs, and locked front diffs daily driving. The internet always says locked front diffs in the snow means you can’t turn, it’s all internet BS. You adjust your driving to your vehicle. This stuff is only unsafe if your car was unsafe to being with, or someone drives your vehicle without knowing how to handle the modification... which can be said for almost any mod.

Depends on a bunch of variables. Can be just fine.

If it’s shitty welds in an open diff in a car with teeny axle shafts and 150,000 mile bearings then yeah, it may be a bad idea.

Both differentials have had the spidergears grenade. I also live up a mile long dirt road that gets very muddy. Welding the diff cost $40. Replacing the diff cost in excess of $200. That and one wheel peel is unacceptable. So why wear drive train components? Because it’s cheaper(I’m only destroying an already ruined diff) and more importantly more fun.
