Spartan locker install and review.
Considering I have spent years plowing with part time transfer cases in 4wd on the pavement, dry pavement mind you also. And not once had a problem.
I consider this jibberish for the joe.
I am not advocating running your part time on dry pavement constantly. There is no reason. But I am not ignorant enough to believe that running said transfer case on the dry pavement for a day will blow my spider gears out.
No offense to anyone at all. Its not meant as such.

Why were you plowing dry pavement? :P
Did the trucks you were driving have locking hubs?
I never said it would blow out your spiders. It just puts added (unnecessary) stress on your driveline, from turning sharp and from your tires not being an identical height. Driving in part time with a front locker on the street is a terrible idea. If you made any sharp turns, I'm sure something would have grenaded unless you had terrible tires.

Transfer was a np261c part time unit.
Also if the spartan can't handle winter driving then its going up for sale. You always can end up on dry pavement, even in winter.
But considering there was no warning label to my knowledge, I think we will be fine.
The jeep and other 4wd's are made knowing people will run them in winter in 4wd. And not always on snow.
The biggest concern is not breakage but rather adverse handling affects.

Its not that. The front end was open. Would not have made a difference. The np231 you can drive on pavement. Really don't know where that came from? Unless you are running different size front tires than rear tires? The NP231 is like any other direct drive transfer case. It puts equal power to the front and rear axles. Thats it. You will not hurt the transfer case or the front axles any more than the rear axle. Whoever told you this is wrong. Anywho there is no reason to continually drive it on dry pavement in 4wd.
Anyways the spartan is doing grand, pavement and all. Took it off roading again this weekend. performed flawlessly

It because there's no differentiation in that transfer case between the front and rear axle. That's why it's called part time 4wd, because you can't run it on just any surface, ie. Pavement. Btw, be careful with the Spartan cam gears, they tend to put uneven pressure on the hardened cross pin shaft which is why their hardened cross pins have such a high fail rate.

From the president of Torq masters Inc the makers of the Aussie. After our last little debate I called around to get info from manufactures and the Aussie guy said their carrier/cross pin fail rate is far far lower then Spartans because of the way the cam gear distributes pressure over the entire cross shaft as opposed to Spartans design. He directed me to pirate4x4.com to compare reviews. While I will admit to obvious bias in mine and the Aussie prez cases, but you sure can find a ton of Spartan failure stories on line and they are much newer then Aussies. 

I am not brand loyal to nothing. Not even my jeep. May the best product win in my opinion

Honestly, I am not being careful with this spartan at all. I will drive on dry pavement. I will abuse the locker, and I will report back.
If it breaks then everyone will know. I will not use a product if I have to be on pins and needles. so consider this review VALID! LOL
And so far its taken the dry pavement, and my offroading. That and its a damaged spartan from where my carrier came apart. The cross pin is a stock cross pin from the spider gears.

And just for clarity. Can you run part time 4wd on dry rocks?
