Two Wheeled Terror!

I've had it with this one sided burn-out thing. If I'm on dead flat ground and power brake it, all four rears will lay 'em down. But if I'm sitting at an angle, it'll more than likely spin just the right pair. Same thing rolling, sorta, when going 35 or so and punching it it'll spin just the right side, but turn a little left an punch it at the same speed and the left side spins.
When it's wet, it spins all four rears.
What is it dependent on?
Which 'lockers' work best on our trucks?

1. Ackerman's Principle
2. Differentialing action
3. Axle shaft length.

so you either live with it, or get a locker

You can tear it down and put another clutch disk and plate in it (both sides). Just do not go over 185 pounds of breakaway or you will not be able to drive it on a wet road.

For on road use a locker is not going to be able to stay engaged (unless it has some sort of slip mechanism) when going around a turn the outboard wheels/ axles spin faster than the wheels/axles on the inside of the turn. in other words if you are turning right the wheels on the left side of the truck have to make up more ground than the wheels on the right side of the truck, and axle binding will occur if the axles are locked. if the axles bind to much, something has to give , usually an axle shaft, or a pinion

Thats what detroit lockers do, if you are on the go pedal, they are locked.

If you are not on the throttle around a turn, it works like an open diff. If you go around a turn and you are on the throttle, it will lock them, and will wear the inside tire a little more. On vehicles with smaller factory axles (jeeps and even some half tons) axle shaft breakage is more common, and not that it doesnt happen, but sterlings are pretty tough in the axle shaft dept, look at the people pulling with them, how many shafts has mech2161 (sp?) broken? Now if he put maybe 37+ inch tires on his dually, and put a detroit, its more possible to break stuff, but on factory tires I really dont see the issue. Just a little more tire wear. I just know, that when Im on the throttle, whether it be reverse or forward, both tires always spin, doesnt matter if ones on pavement and ones on ice. I love my detroit.

Also, I think SolidGround runs around with a detroit in his dually. Which reminds me of one more thing, duallys usually have dana 80s, which are even larger / tougher axles then the sterlings! Detroit it and dont look back!

First just change the fluid, thats the cheapest. I had a one wheel burnout axle all the time until i changed the fluid, didn't add any friction modifier, it doesnt chirp or hop, but it never lets one wheel have all the fun. Both wheels all the time!

I say change the fluid while you're changing your clutch disks on the factory limited slip. For the money, this is your best bet.

A detriot installed on your truck professionally will run you around $800.

I'm not sure about you but I've done plenty of wheeling and detriots are nothing but a pain in the *** for daily drivers. Especially full sizes!

my $.02

I guess its to each their own, I DD my truck, and drive 30-40k a year on it, and I absolutely love my detroit. Mines 4wd, ECSB and weighs in at 8700ish everyday with 295/75 16 tires.

Your rear end will hook with a detriot, that's for sure. I'm just not a fan of the violent locking and unlocking. Maybe it's not so bad with smaller tires. My vehicles with detriots have always had 35" + tires.

Actually, mine doesnt have any violence. I think mines what they call a detroit soft locker. Ill have to find my paperwork if its still around. Theres no noise, except the occasional once or twice a month random unlock that happens when coming to a red light and having to slow down after accellerating hard. When I hit the gas, they are just locked, almost no noise, and you cant hear it unlock. The biggest notable thing that happens is it seems like there is more driveline play, but thats the nature of the locker. When I had my tranny done, the tech said to me he thought there was waaaay too much excessive backlash, just because he coudl turn the driveshaft more then normal. Its just the locker though, i think its not uncommon for them to beable to turn 1/4 turn before it turns the wheels. Its not that the gears arent turning, its how the locking mechanism works inside the case.

Awwww. Here is where we differ rebel. I've always ran full detriots in my rigs. Full detriots aren't the quietest locker on the planet.

If you have a soft locker it's most likely a truetrac. These are a good alternative to the factory limited slip but cost good $$$

The unit that I really like so far is made by Eaton. It's called the E-locker. They are acutuated with an electrical push button switch on the dash. You can run open/off on the road for the good manners of a limited slip, or hit the button for the manners of a full locker. The best part is that you can run them in both the front and the rear. I have never ran one of these unit's myself, but form what I've read in the Four wheeler mag's they are a pretty incredible unit. I believe they are a factory install on some of the Range Rovers. Anyhow just my 2 cent's. Take care. Country

Nope, its a full detroit locker. Like I said, Ill try and find my documentation. I know for a fact its not a truetrac or any type of limited slip, its a locker.

I changed the fluid to no avail, the fluid I removed wasn't bad and didn't smell burnt, there wasn't anything foreign, either. Still a two wheeler peeler.

So a locker I'll be shopping for. Don't know if I want a 'full locker' because of the noise an binding.
Is the TrueTrac just a softer version of the Detroit?

Who knows what about the E-Locker from Eaton. Would be nice to lock and unlock.

-Thanks, Robby
